ABSTRACT
The use of the nasal route for the delivery of challenging drugs such
as small polar molecules, vaccines, hormones, peptides and proteins
has created much interest in nowadays. Due to the high permeability,
high vasculature, low enzymatic environment of nasal cavity and
avoidance of hepatic first pass metabolism are well suitable for
Systemic delivery of drug molecule via nose Many drug delivery
devices for nasal application of liquid, semisolid and solid
formulation are investigated to deliver the drugs to the treat most
crisis CNS diseases (i.e., Parkinson’s dis-ease, Alzheimer’s disease)
because it requires rapid and/or specific targeting of drugs to the
brain. It is well suitable for the delivery of biotechnological products
like proteins, peptides, hormones, DNA plasmids for DNA vaccines
to give enhanced bioavailability. This review sets out to discuss some
factors affecting nasal absorption, bioavailability barriers, strategies
to improve nasal absorption, new developments in nasal dosage form
design and applications of nasal drug delivery system.

INTRODUCTION
Nasal mucosa has been considered as a potential ad-
ministration route to achieve faster and higher level of
drug absorption because it is permeable to more com-
pounds than the gastrointestinal tract due to lack of
pancreatic and gastric enzymatic activity, neutral pH
of the nasal mucus and less dilution by
gastrointestinal contents . In recent years many drugs
have been shown to achieve better systemic
bioavailability through nasal route than by oral
administration. Nasal therapy, has been recognized
form of treatment in the Ayurvedic systems of Indian
medicine, it is also called “NASAYA KARMA”
(Chien YW et al., 1989).
This review article provides a brief overview of the
ad-vantages and limitations of nasal drug delivery
system and anatomy of nasal cavity, mechanism of
nasal ab-sorption, barriers to nasal absorption,
strategies to improve nasal absorption, nasal drug
delivery formulation issues and applications of nasal
drug delivery systems.
Anatomy and physiology of Nasal Cavity:
The nasal cavity is divided into two halves by the
nasal septum and extends posterior to the
nasopharynx, while the most anterior part of the nasal
cavity, the nasal vestibule, opens to the face through
the nostril. The nasal cavity consists three main
regions are nasal vestibule, olfactory region and

respiratory region. The surface area in the nose can be
enlarges about 150cm2 by the lateral walls of the
nasal cavity includes a folded structure, it is a very
high surface area compared to its small volume. This
folded structure consists of three turbinate’s the
superior, the median and the inferior (Michael et al.,
2005).The main nasal airway having the narrow
passages, usually it has 1-3mm wide and these
narrows structures are useful to nose to carryout its
main functions. The nasal cavity is covered with a
mucous membrane which can be divided into two
areas; nonolfactory and olfactory epithelium, in this
non-olfactory area includes the nasal vestibule which
is covered with skin-like stratified squamous
epithelium cells, where as respiratory region, which
has a typical airways epithelium covered with
numerous microvilli, resulting in a large surface area
available for drug absorption and transport (Sarkar
MA, 1992).In this way the mucus layer is propelled in
a direction from the anterior to-wards the posterior
part of the nasal cavity. The goblet cells are present in
the mucus membrane which covers the nasal turbinate
and the atrium; it secretes the mucus as mucus
granules which are swelling in the nasal fluid to
contribute to the mucus layer. The mucus secretion is
composed of about 95% water, 2 % mucin, 1% salts,
1% of other proteins such asal-bumin,
immunoglobulin s, lysozyme and lactoferrin, and b
1% lipids (Kaliner M et al.,1984).The mucus
secretion gives immune protection against inhaled
bacteria and viruses. It also performs a number of
physiological functions. (1) It covers the mucosa,and
physically and enzymatically protects it. (2) The
mucus has water-holding capacity. (3) It exhibits
surface electrical activity. (4) It permits efficient heat
transfer. (5) It acts as adhesive and transport s
particulate matter towards the nasopharynx(Bernstein
JM et al., 1997).
Advantages:
1. Drug degradation that is observed in
gastrointestinal tract is absent.
2. Hepatic first pass metabolism is absent.
3. Rapid drug absorption and quick onset of action
can be achieved.
4. Bioavailability of the large drug molecules can be
improved by means of absorption enhancer or
other approach.
5. Availability for the smaller a drug molecule is
good.
6. Drugs that cannot be morally absorb can be
reached to the systemic circulation by the nasl
route.
7. Convenient for the patients those who are on
long-term therapy when compared with parental
medication.
8. Large nasal mucosal surface area for drug
absorption.
9. Rapid drug absorption via highly vascularized
mucosa.
Limitations:
1. The histological toxicity of absorption enhancers
used in nasal drug delivery system is not yet
clearly established.
2. Relatively inconvenient to patients when
Compared to oral delivery systems since there is a
Possibility of nasal irritation.
3. Nasal cavity provides smaller absorption surface
Area when compared to GIT.
Mechanism of Action:
1. The first mechanism involves an aqueous route of
transport, which is also known as paracellular
route. This route is slow and passive. There is an
inverse log-log correlation between intranasal
absorption and the molecular weight of water
soluble compounds. Poor bioavailability was
observed for drug with a molecular weight greater
than 1000 Daltons.
2. The second mechanism involves transport
through a lipoidal route is also known as the
transcellular process and is responsible for the
transport of lipophilic drugs that show a rate
dependency on their lipophilicity
3. Drug also cross cell membranes by an active
transport route via carrier-mediated means or
transport through the opening of tight junctions.
For examples, chitosan, a natural biopolymer
from shellfish, opens tight junctions between
epithelial cells to facilitate drug transport.
Factors Affecting Drug absorption: Factors affect
the systemic bioavailability of nasally administered
drugs. The factors can be attributed to the
physicochemical properties of the drugs and the
characteristics of other ingredient of delivery system
has been discussed in relevant section i.e. dosage.
Forms and type and characteristics of selected nasal
drugs delivery system. These play significant role for
most of the drugs in order to reach therapeutically
effective blood levels after nasal administration. The
factors influencing nasal drug absorption are as
follows.
1. Physicochemical properties of drug:
Chemical form of the drug
Polymorphism
Properties of the drug
Molecular weight
Particle size
Solubility and dissolution rate

2. Nasal effect:
Membrane permeability
Environmental PH
Cold, Rhinitis
Mucociliary clearance.
3. Delivery Effects:
Drugs distribution and deposition.
Formulation effect on mucociliary clearance.
effect on ciliary function and epithelial
Membranes
Pharmacokinetics of Nasal Absorption: Factors
reported to affect the pharmacokinetic parameters
following intranasal administration are:
1. Physiology-related factors, such as
A. speed of mucus flow
B. presence of infection
C. atmospheric conditions
2. Dosage form related factors such as
A. concentration of active drug
B. physicochemical properties of active drug
C. density/ viscosity properties of formulations
D. pH/toxicity of dosage form
E. pharmaceutical excipients used
3. Administration related factors such as
A. size of droplet
B. size of deposition
C. mechanical loss into the oesophagus
D. mechanical loss into other regions in the nose
E. mechanical loss anteriorly from nose
Safety and efficacy of absorption enhancers:
1. Mucociliary transport rate:
It is measured using a Frog palate model to test
potential toxicity of Absorption enhancers L-α-
lysophosphatidylcholine, Sodium deoxycholate and
taurocholate, laureth-s and Sodium
taurodihydrofusidate irreversibly halted the Mucus
transport rate.
2. Nasal morphology:
This was studied by differing the contact times with
the nasal epithelium using Scanning electron
microscope to detect gross Structural and cellular
changes, ciliary identity as well As prevalence or
extra-cellular debris. Morphological
Damage caused by enhancers in the increasing order
is: GC<<STDHF<<LAURETH-9<DC=TDC.
3. ciliary beat frequency:
chicken embryo Tracheal tissue and human adenoid
tissue were used to Measure the in vitro reduction of
the ciliary beat Frequency caused by various
enhancers ranging from Laureth-9=DC =GC=TDC
(fast and irreversible ciliostasis, Brought about by
preservatives like BAK and Mercury Compounds).
Excipients used in nasal formulation:
Commonly used excipients that are frequently added
to nasl preparations can be listed below
1. Bioadhesive polymers: it can be defined as a
compound that is capable of interacting with
biological materials through interfacial forces and
being retained on search material for prolonged
period of time if the biological material is a
mucous membrane the Bioadhesive material is
term as a mucoadhesive on molecular level muco
edition can be explained on the basis of attraction
molecular interactions involving forces such as
Van der Waals, electrostatic interactions,
hydrogen bonding and hydrophobic interactions.
The bioadhesive material of a polymer material is
dependent on the nature of polymer the
surrounding medium pH swelling and
physiological factors such as mucin turnover
disease state.
Examples of some bioadhesive polymers employed
for nasal drug delivery systems:
A. Carbopol
B. Sodium carboxymethyl cellulose
C. Hydroxypropyl cellulose
D. Hydroxypropyl methyl cellulose
E. Hydroxyethyl cellulose
F. Methyl cellulose
G. Guar gum
H. Sodium alginate
I. Starch
J. Dextran
K. Chitosan.
2. Gelling agent: according to a studyof pennington
increasing solution viscosity may provide a
means of prolonging the therapeutic effect of
nasal preparation show that a drug carrier such as
hydroxypropyl cellulose was effective for
improving the absorption of the low molecular
weight drugs but did not produce the same effect
for high molecular weight peptides use of a
combination of a carriers is often recommended
from a safety point of view.
3. Penetratration enhancer: chemical penetration
enhancers are widely used in a national Drug
delivery classification of chemical penetretion
includes the following
A. Solvents
B. Alkyl dimethyl sulfoxide
C. Pyrrolidones
D. Surfactants
Mechanism of penetration enhancers is as follows:
Increasing cell membrane permeability

Opening tight junction and formation of
intracellular aqueous channels
Increasing lipophilicity of the charge drug by
forming iron pair
Inhibiting proteolytic activity
4. Buffers: Nasal formulations are generally
administered in small volumes ranging from 25 to
200 microliter with hundred microliter being the
most common dose volume.
Hans Nasir secretions may alter the pH of the
administered dose. This can affect the
concentration of an ionized drug available for
absorption. For an adequate formulation buffer
capacity may be required to maintain the pH in
situ.
5. Solubilizers: aqueous solubility of a drug is
always a limitation for nasal drug delivery in a
solution. Convectional solvents for co solvent
such as glycols small quantities of alcohol
transcutol glycol monoethyl ether medium chain
triglycerides and labrasol can be used to enhance
the solubility of the drugs. Other options includes
the use of surfactants or cyclodextrin such as HP
beta cyclodextrin that serve as a biocompatible
solubilizer and stabilizer in combination with the
lipophilic Absorption enhancers.
6. Preservatives: most nasal formulations are
equispaced and need preservatives to prevent
microbial growth parabens benzalkonium chloride
phenyl ethyl alcohol and benzyl alcohol are some
of the commonly used preservatives in another
formulations have shown that the Mercury
containing preservatives have a fast and
irreversible effect on the ciliary movement and
should not be used in nasal system.
7. Antioxidants: a small quantity of antioxidants
may be required to prevent drug oxidation.
Commonly used antioxidants are sodium
metabisulfite Sodium bisulfite butylated
hydroxytoluene and tocopherol.
8. Humectants: many allergic and chronic
diseases are often connected with crossed and drying
of mucous membrane. Certain preservatives
antioxidants among other excipients are also likely to
cause nasal irritation especially when used in higher
quantity. Adequate internal moisture is essential for
preventing the hydration. Therefore humic terms can
be added especially in a gel based Nasal products.
Human things avoid nasal irritation are not likely to
infect drug absorption examples include glycerine
sorbitol and mannitol.
9. Surfactants: incorporation of surfactant into
nasal dosage form could modify the permeability of
nasal membranes which may facilitate the nasal
absorption of drug..
Enhancement of nasal absorption: several
methods have been used to facilitate the nasal
absorption of drugs:
Structure modification: The chemical
modification of a drug molecule has been
commonly used to modify the physicochemical
properties of drug and could also be utilized to
improve the nasal absorption of the drug.
Salt or Easter formulation: the drug could be
converted to form of a salt or an Easter for better
transnasal permeability. For example, nasal
absorption could be improved significantly by
forming a salt with increase solubility in measure
fluid for an Easter with enhanced uptake by nasal
epithelium.
Formulation design: proper selection of
Pharmaceutical excipients in the development of
national formulation could enhance the
formulation stability for the nasal bioavailability
of the drug.
Surfactants: incorporation of surfactant into
nasal dosage form could modify the permeability
of national membranes which may facilitate the
national absorption of drug survey of the
literature indicates that surfactants have been
extensively evaluated for the possibility of
enhancing the nasal absorption of drugs including
peptide and protein drugs a number of surfactant
has been reported to enhance the absorption of
drugs through the nasal mucosa to a level
sufficient achieve their systemic effect.
Research and development in nasal drug delivery:
Most of the over the counter nasal preparation are
Formulated as solution, to treat the nasal symptoms of
Allergic rhinitis and common cold. A simple drug
solution is adequate for this purpose as it produces
better dispersion over greater surface area. The nasal
residence time of such formulation is short (3-20 min)
and exhibit high inter individual variability. This
route provides fast peak levels in circulation 15 Large
number of drugs has been evaluated for Systemic
bioavailability after transnasal administration In
experimental animal models. Transnasal
Administration of drugs in diverse dosage forms such
As sprays, powders, and microspheres has been
Attempted for improved residence and bioavailability.
The nasal delivery is receiving attention for
management of postoperative pain; mucosal
administration requires only a 1.1-1.5 time higher

dose of fentanyl than i.v. dose. The nasal delivery of
vaccines is a very attractive route of administration in
terms of efficacy.
Various Dosage Forms used: There are several
delivery systems which have been used for the
delivery of drugs through the nasal cavity. The
selection of delivery system depends upon the drug
being used, proposed indication, patient population
and last but Not least, marketing preferences. Some of
these delivery systems and their important features
are
Summarized below:
Nasal drops
Nasal sprays
Nasal gels
Nasal powders
Nasal drops: Nasal drops are one of the most simple
and convenient systems developed for nasal delivery.
The main disadvantage of this system is the lack of
the dose precision and therefore nasal drops may not
be suitable for prescription products. It has been
reported that nasal drops deposit human serum
albumin in the nostrils more efficiently than nasal
sprays. Technetium -99m- labeled human serum
albumin was administered into the human nose by
nasal spray or nasal drops. The results showed that
about 40%of the dose cleared rapidly with average
halftimes ranging from 6 to 9.
Nasal sprays: Both solution and suspension
Formulations can be formulated into nasal sprays.
Due to the availability of metered dose pumps and
Actuators, a nasal spray can deliver an exact dose
from 25 to 200 µm. The particles size and
morphology (for suspensions) of the drug and
viscosity of the formulation determine the choice of
pump and actuator assembly.
Various nasal spray systems: A current trend is to
Develop preservative free formulations. In a
traditional Formulation basically the preservative
takes care of a posssible contamination issue. An
unpreserved formulation has to rely on the integrity of
the primary packaging.
This means in detail that the responsibility is shifted
towards the manufacturer and supplier of the
dispersing system. A typical example of a nasal spray
system designed to administer sterile formulation. A
spring loaded mechanical scaling system, which is
located directly behind the small orifice in the nasal
actuator, prevents through its fast opening and closing
profile a possible contamination from entering the
primary packaging. When dispensing out of an
airtight container a vaccum will built up. In the pump
system, integrated microbiological filter holds back
any contamination and allows the ventilation of the
package.
Nasal gels: Nasal gels are high-viscosity thickened
Solutions or suspensions. Until the recent
development of precise dosing device, there was not
much interest In this system. The advantages of a
nasal gel includes The reduction of post-nasal drip
due to high viscosity, reduction of taste impact due to
reduced swallowing, reduction of of anterior leakage
of the formulation, reduction of irritation by using
soothing/emollient excipients and target to mucosa
for better absorption.
Entsol nasal gel: Entsol nasal gel is a drug free
Hypertonic saline gel with aloe and vitamin E. It
Provides soothing, moisturizing relief to dry, stuffy,
irritated nasal passages. Entsol nasal gel also helps
relieve nasal congestion by reducing edema and
swelling, fast and effectively. It is ideal for people
using CPAP machines for sleep apnea since the
constant flow of air teds to dry out nasal passages. It
is also very useful in dry climates of low humidity
such as indoors During the winter, some of the dry
western states and for individuals with nasal allergies
or sinusitis.
Nasal powder: This dosage form may be developed
if solution and suspension dosage forms cannot be
developed e.g., due to lack of drug stability. The
advantages to the nasal powder dosage form are the
absence of preservative and superior stability of the
formulation. However, the suitability of the powder
formulation is dependent on the solubility, particles
size, aerodynamic properties and nasal irritancy of the
active drug and/or excipients. Local application of
Drug is another advantage of this system. But nasal
mucosa irritancy and metered dose delivery are some
of the challenges for formulation scientists and device
manufacturers
Evaluation of Nasal Drugs:
A. vitro nasal permeation studies: Various aproaches
used to determine the drug diffusion through nasal
mucosa from the formulation. The two important
methodologies to study the diffusion profile of the
drug are discussed here,
In vitro diffusion studies: The nasal diffusion cell is
fabricated in glass. The water jacketed recipient
chamber has total capacity of 60 ml and a flanged top
of about 3mm; the lid has 3 opening, each for
sampling, Thermometer, and a donor tube chamber.
The 10 cm long donor chamber, and a donor tube
chamber has total capacity of 60 ml and a flanged top
of about 3mm; the lid has 3 openings, each for
sampling, thermometer, and A donor tube chamber

diameter of 1.13 cm. The nasal mucosa of sheep was
separated from sub layer bony tissues and stoned in
distilled water containing few drops at genatamycin
injection.
After the complete removal of blood from muscosal
surface, is attached to donor chamber tube. The donor
chamber tube is placed such a way that it just touches
the diffusion medium in recipient chamber. At
predetermined intervals, samples (0.5 ml) from
recipient chamber are with draw and transferred to
amber colored ampoules. The samples withdrawn are
suitably replaced. The samples are estimated for drug
content by suitable analytical technique.
Throughout the experiment the temperature is
Maintained at 37oC.
A) Vivo Nasal Absorption studies Animal
models for nasal absorption studies: The Animal
models employed for nasal absorption studies can be
of two types, viz., whole animal or in vivo model and
an isolated organ perfusion or ex vivo model. These
models are discussed in detail below:
Rat Model: The surgical preparation of rat for in vivo
Nasal absorption study is carried out as follows: The
rat Is anaesthetized by intraperitoneal injection of
sodium
Pentobarbital. An incision is made in the neck and the
Trachea is cannulated with a polyethylene tube.
Another tube is inserted through the oesophagus
towards the posterior region of the nasal cavity. The
passage of the nasopalatine tract is sealed so that the
drug solution is not drained from the nasal cavity
through the mouth. The drug solution is delivered to
the nasal cavity through the nostril or through the
cannulation tubing. The blood samples are collected
from the femoral vein. As all the probable outlets of
drainage are blocked, the drug can be only absorbed
and transported into the systemic circulation by
Penetration and/or diffusion through nasal mucosa.
Rabbit Model: The rabbit offers several advantages
As an animal model for nasal absorption studies:
1. It is relatively cheap, readily available and easily
Maintained in laboratory settings
2. It permits pharmacokinetic studies as with large
Animals (like monkey)
3. The blood volume is large enough (approx.
300ml)
4. To allow frequent blood sampling (l-2ml)
Thus it permits full characterization of the absorption
and determination of the pharmacokinetic profile of a
drug. Rabbits (approx. 3 kg) are either anaesthetized
or maintained in the conscious state depending on the
purpose of study. In the anaesthetized model, the
Rabbit is anaesthetized by an intramuscular injection
of A combination of ketamine and xylazine. The
rabbit’s Head is held in an upright position and the
drug Solution is administered by nasal spray into each
Nostril. During the experiment the body temperature
of the rabbit is maintained at 37°C with the help of a
heating pad. The blood samples are collected by an
Indwelling catheter in the marginal ear vein or artery.
Dog Model: The dog is either anaesthetized or
retained hi the conscious condition depending on the
drug characteristics and the purpose of experiment.
The dog is anaesthetized by intravenous injection of
sodium thiopental and the anesthesia is maintained
wiith sodium Phenobarbital. A positive pressure
pump through a cuffed endotracheal tube gives the
Ventilation. The body temperature is maintained at
37-38°C by a heating pad. The blood sampling is
carried out from the jugular vein.
Ex vivo Nasal Perfusion Models:
Surgical Preparation is the same as that is for in vivo
rat model. During the perfusion studies, a funnel is
placed Between the nose and reservoir to minimize
the loss of Drug solution. The drug solution is placed
in a reservoir maintained at 37°C and is circulated
through the nasal cavity of the rat with a peristaltic
pump. The perfusion Solution passes out from the
nostrils (through the Funnel) and runs again into the
reservoir. The drug Solution in the reservoir is
continuously stirred. The Amount of drug absorbed is
estimated by measuring The residual drug
concentration in the perfusing Solution. The drug
activity due to stability problems May be lost during
the course of experiment. This is Especially true for
peptide and protein drugs that may Undergo
proteolysis and aggregation. Rabbit can also be used
as the animal model for ex vivo Nasal perfusion
studies. The rabbit is anaesthetized With parenteral
uretliane-acepromazine. A midline Incision is made
in the neck and the trachea is Cannulated with a
polyethylene neonatal endotracheal Tube. The
oesophagus is isolated and ligated. The distal End of
the oesophagus is closed with suture and Flexible
tygon tubing is inserted into the proximal end And
advanced to the posterior part of the nasal cavity. The
nasopalatine tract (that connects nasal cavity to The
mouth) is closed with an adhesive to avoid Drainage
of drug solution from the nasal cavity. The Drug in
isotonic buffer solution is recirculated using a
Peristaltic pump
Scintigraphic evaluation in rabbits of nasal drug

colloidal albumin in Rabbit nasal cavity was
evaluated by gamma Scintigraphy. This technique
was used to compare the Nasal clearance of
preparations based either on Carbopol 971P^® or
lactose (control), each with and Without
apomorphine, or carboxymethylcellulose with
Apomorphine. The planar 1-min images showed an
excipient dependent progressive migration of
radioactivity with time from the nasal cavity to the
stomach and intestine. Thirty minutes post
insufflation, the Percentages of the formulations
cleared from the nasal Cavity were 47% for lactose,
26% for Lactose/apomorphine, 10% for Carbopol
971P^®, and 3% for both Carbopol
971P^®/apomorphine and Carboxymethylcellulose
/apomorphine. Three hours post insufflation, the
percentages of the Formulations cleared from the
nasal cavity were 70% For lactose, 58% for
lactose/apomorphine, 24% for Carbopol 971P^®,
12% for Carbopol971P^®/Apomorphine, and27 For
Carboxymethylcellulose/ apomorphine. Apomorphine
inhibited Nasal mucociliary clearance since migration
of the radioactivity administered with apomorphine
containing preparations was in all cases slower than
that of the corresponding powder without
Apomorphine. The peak plasma concentration of
apomorphine was attained while all the formulations
were still within the Nasal cavity. The use of
mucoadhesive polymers such as carbopol 971P^® or
carboxymethylcellulose in nasal dosage forms
increases their residence time within the nasal cavity
and provides the opportunity for sustained nasal drug
delivery.

  • 1. International Journal of Trend in Scientific Research and Development (IJTSRD) Volume 5 Issue 5, July-August 2021 Available Online: www.ijtsrd.com e-ISSN: 2456 – 6470 @ IJTSRD | Unique Paper ID – IJTSRD43868 | Volume – 5 | Issue – 5 | Jul-Aug 2021 Page 572 Nasal Drug Delivery System: A Review Aarti C. Nangare, Sujit Kakade, Ashok Bhosale Shankarrao Ursal College of Pharmaceutical Sciences and Research Centre, Pune, Maharashtra, India ABSTRACT The use of the nasal route for the delivery of challenging drugs such as small polar molecules, vaccines, hormones, peptides and proteins has created much interest in nowadays. Due to the high permeability, high vasculature, low enzymatic environment of nasal cavity and avoidance of hepatic first pass metabolism are well suitable for Systemic delivery of drug molecule via nose Many drug delivery devices for nasal application of liquid, semisolid and solid formulation are investigated to deliver the drugs to the treat most crisis CNS diseases (i.e., Parkinson’s dis-ease, Alzheimer’s disease) because it requires rapid and/or specific targeting of drugs to the brain. It is well suitable for the delivery of biotechnological products like proteins, peptides, hormones, DNA plasmids for DNA vaccines to give enhanced bioavailability. This review sets out to discuss some factors affecting nasal absorption, bioavailability barriers, strategies to improve nasal absorption, new developments in nasal dosage form design and applications of nasal drug delivery system. KEYWORDS: Bioavailability, Patient Compliance, First pass effect, absorption Enhancers How to cite this paper: Aarti C.

In recent years many drugs have been shown to achieve better systemic bioavailability through nasal route than by oral administration. Nasal therapy, has been recognized form of treatment in the Ayurvedic systems of Indian medicine, it is also called “NASAYA KARMA” (Chien YW et al., 1989). This review article provides a brief overview of the ad-vantages and limitations of nasal drug delivery system and anatomy of nasal cavity, mechanism of nasal ab-sorption, barriers to nasal absorption, strategies to improve nasal absorption, nasal drug delivery formulation issues and applications of nasal drug delivery systems. Anatomy and physiology of Nasal Cavity: The nasal cavity is divided into two halves by the nasal septum and extends posterior to the nasopharynx, while the most anterior part of the nasal cavity, the nasal vestibule, opens to the face through the nostril. The nasal cavity consists three main regions are nasal vestibule, olfactory region and IJTSRD43868

International Journal of Trend in Scientific Research and Development @ www.ijtsrd.com eISSN: 2456-6470 @ IJTSRD | Unique Paper ID – IJTSRD43868 | Volume – 5 | Issue – 5 | Jul-Aug 2021 Page 573 respiratory region. The surface area in the nose can be enlarges about 150cm2 by the lateral walls of the nasal cavity includes a folded structure, it is a very high surface area compared to its small volume. This folded structure consists of three turbinate’s the superior, the median and the inferior (Michael et al., 2005).The main nasal airway having the narrow passages, usually it has 1-3mm wide and these narrows structures are useful to nose to carryout its main functions. The nasal cavity is covered with a mucous membrane which can be divided into two areas; nonolfactory and olfactory epithelium, in this non-olfactory area includes the nasal vestibule which is covered with skin-like stratified squamous epithelium cells, where as respiratory region, which has a typical airways epithelium covered with numerous microvilli, resulting in a large surface area available for drug absorption and transport (Sarkar MA, 1992).In this way the mucus layer is propelled in a direction from the anterior to-wards the posterior part of the nasal cavity. The goblet cells are present in the mucus membrane which covers the nasal turbinate and the atrium; it secretes the mucus as mucus granules which are swelling in the nasal fluid to contribute to the mucus layer. The mucus secretion is composed of about 95% water, 2 % mucin, 1% salts, 1% of other proteins such asal-bumin, immunoglobulin s, lysozyme and lactoferrin, and b 1% lipids (Kaliner M et al.,1984).The mucus secretion gives immune protection against inhaled bacteria and viruses. It also performs a number of physiological functions. (1) It covers the mucosa,and physically and enzymatically protects it. (2) The mucus has water-holding capacity. (3) It exhibits surface electrical activity. (4) It permits efficient heat transfer. (5) It acts as adhesive and transport s particulate matter towards the nasopharynx(Bernstein JM et al., 1997). Advantages: 1. Drug degradation that is observed in gastrointestinal tract is absent. 2. Hepatic first pass metabolism is absent. 3. Rapid drug absorption and quick onset of action can be achieved. 4. Bioavailability of the large drug molecules can be improved by means of absorption enhancer or other approach. 5. Availability for the smaller a drug molecule is good. 6. Drugs that cannot be morally absorb can be reached to the systemic circulation by the nasl route. 7. Convenient for the patients those who are on long-term therapy when compared with parental medication. 8. Large nasal mucosal surface area for drug absorption. 9. Rapid drug absorption via highly vascularized mucosa. Limitations: 1. The histological toxicity of absorption enhancers used in nasal drug delivery system is not yet clearly established. 2. Relatively inconvenient to patients when Compared to oral delivery systems since there is a Possibility of nasal irritation. 3. Nasal cavity provides smaller absorption surface Area when compared to GIT. Mechanism of Action: 1. The first mechanism involves an aqueous route of transport, which is also known as paracellular route. This route is slow and passive. There is an inverse log-log correlation between intranasal absorption and the molecular weight of water soluble compounds. Poor bioavailability was observed for drug with a molecular weight greater than 1000 Daltons. 2. The second mechanism involves transport through a lipoidal route is also known as the transcellular process and is responsible for the transport of lipophilic drugs that show a rate dependency on their lipophilicity 3. Drug also cross cell membranes by an active transport route via carrier-mediated means or transport through the opening of tight junctions. For examples, chitosan, a natural biopolymer from shellfish, opens tight junctions between epithelial cells to facilitate drug transport. Factors Affecting Drug absorption: Factors affect the systemic bioavailability of nasally administered drugs. The factors can be attributed to the physicochemical properties of the drugs and the characteristics of other ingredient of delivery system has been discussed in relevant section i.e. dosage. Forms and type and characteristics of selected nasal drugs delivery system. These play significant role for most of the drugs in order to reach therapeutically effective blood levels after nasal administration. The factors influencing nasal drug absorption are as follows. 1. Physicochemical properties of drug: Chemical form of the drug Polymorphism Properties of the drug Molecular weight Particle size Solubility and dissolution rate

Nasal effect: Membrane permeability Environmental PH Cold, Rhinitis Mucociliary clearance. 3. Delivery Effects: Drugs distribution and deposition. Formulation effect on mucociliary clearance. effect on ciliary function and epithelial Membranes Pharmacokinetics of Nasal Absorption: Factors reported to affect the pharmacokinetic parameters following intranasal administration are: 1. Physiology-related factors, such as A. speed of mucus flow B. presence of infection C. atmospheric conditions 2. Dosage form related factors such as A. concentration of active drug B. physicochemical properties of active drug C. density/ viscosity properties of formulations D. pH/toxicity of dosage form E. pharmaceutical excipients used 3. Administration related factors such as A. size of droplet B. size of deposition C. mechanical loss into the oesophagus D. mechanical loss into other regions in the nose E. mechanical loss anteriorly from nose Safety and efficacy of absorption enhancers: 1. Mucociliary transport rate: It is measured using a Frog palate model to test potential toxicity of Absorption enhancers L-α- lysophosphatidylcholine, Sodium deoxycholate and taurocholate, laureth-s and Sodium taurodihydrofusidate irreversibly halted the Mucus transport rate. 2. Nasal morphology: This was studied by differing the contact times with the nasal epithelium using Scanning electron microscope to detect gross Structural and cellular changes, ciliary identity as well As prevalence or extra-cellular debris. Morphological Damage caused by enhancers in the increasing order is: GC<<STDHF<<LAURETH-9<DC=TDC. 3. ciliary beat frequency: chicken embryo Tracheal tissue and human adenoid tissue were used to Measure the in vitro reduction of the ciliary beat Frequency caused by various enhancers ranging from Laureth-9=DC =GC=TDC (fast and irreversible ciliostasis, Brought about by preservatives like BAK and Mercury Compounds). Excipients used in nasal formulation: Commonly used excipients that are frequently added to nasl preparations can be listed below 1. Bioadhesive polymers: it can be defined as a compound that is capable of interacting with biological materials through interfacial forces and being retained on search material for prolonged period of time if the biological material is a mucous membrane the Bioadhesive material is term as a mucoadhesive on molecular level muco edition can be explained on the basis of attraction molecular interactions involving forces such as Van der Waals, electrostatic interactions, hydrogen bonding and hydrophobic interactions. The bioadhesive material of a polymer material is dependent on the nature of polymer the surrounding medium pH swelling and physiological factors such as mucin turnover disease state. Examples of some bioadhesive polymers employed for nasal drug delivery systems: A. Carbopol B. Sodium carboxymethyl cellulose C. Hydroxypropyl cellulose D. Hydroxypropyl methyl cellulose E. Hydroxyethyl cellulose F. Methyl cellulose G. Guar gum H. Sodium alginate I. Starch J. Dextran K. Chitosan. 2. Gelling agent: according to a studyof pennington increasing solution viscosity may provide a means of prolonging the therapeutic effect of nasal preparation show that a drug carrier such as hydroxypropyl cellulose was effective for improving the absorption of the low molecular weight drugs but did not produce the same effect for high molecular weight peptides use of a combination of a carriers is often recommended from a safety point of view. 3. Penetratration enhancer: chemical penetration enhancers are widely used in a national Drug delivery classification of chemical penetretion includes the following A. Solvents B. Alkyl dimethyl sulfoxide C. Pyrrolidones D. Surfactants Mechanism of penetration enhancers is as follows: Increasing cell membrane permeability

Buffers: Nasal formulations are generally administered in small volumes ranging from 25 to 200 microliter with hundred microliter being the most common dose volume. Hans Nasir secretions may alter the pH of the administered dose. This can affect the concentration of an ionized drug available for absorption. For an adequate formulation buffer capacity may be required to maintain the pH in situ. 5. Solubilizers: aqueous solubility of a drug is always a limitation for nasal drug delivery in a solution. Convectional solvents for co solvent such as glycols small quantities of alcohol transcutol glycol monoethyl ether medium chain triglycerides and labrasol can be used to enhance the solubility of the drugs. Other options includes the use of surfactants or cyclodextrin such as HP beta cyclodextrin that serve as a biocompatible solubilizer and stabilizer in combination with the lipophilic Absorption enhancers. 6. Preservatives: most nasal formulations are equispaced and need preservatives to prevent microbial growth parabens benzalkonium chloride phenyl ethyl alcohol and benzyl alcohol are some of the commonly used preservatives in another formulations have shown that the Mercury containing preservatives have a fast and irreversible effect on the ciliary movement and should not be used in nasal system. 7. Antioxidants: a small quantity of antioxidants may be required to prevent drug oxidation. Commonly used antioxidants are sodium metabisulfite Sodium bisulfite butylated hydroxytoluene and tocopherol. 8. Humectants: many allergic and chronic diseases are often connected with crossed and drying of mucous membrane. Certain preservatives antioxidants among other excipients are also likely to cause nasal irritation especially when used in higher quantity. Adequate internal moisture is essential for preventing the hydration. Therefore humic terms can be added especially in a gel based Nasal products. Human things avoid nasal irritation are not likely to infect drug absorption examples include glycerine sorbitol and mannitol. 9. Surfactants: incorporation of surfactant into nasal dosage form could modify the permeability of nasal membranes which may facilitate the nasal absorption of drug.. Enhancement of nasal absorption: several methods have been used to facilitate the nasal absorption of drugs: Structure modification: The chemical modification of a drug molecule has been commonly used to modify the physicochemical properties of drug and could also be utilized to improve the nasal absorption of the drug. Salt or Easter formulation: the drug could be converted to form of a salt or an Easter for better transnasal permeability. For example, nasal absorption could be improved significantly by forming a salt with increase solubility in measure fluid for an Easter with enhanced uptake by nasal epithelium. Formulation design: proper selection of Pharmaceutical excipients in the development of national formulation could enhance the formulation stability for the nasal bioavailability of the drug. Surfactants: incorporation of surfactant into nasal dosage form could modify the permeability of national membranes which may facilitate the national absorption of drug survey of the literature indicates that surfactants have been extensively evaluated for the possibility of enhancing the nasal absorption of drugs including peptide and protein drugs a number of surfactant has been reported to enhance the absorption of drugs through the nasal mucosa to a level sufficient achieve their systemic effect. Research and development in nasal drug delivery: Most of the over the counter nasal preparation are Formulated as solution, to treat the nasal symptoms of Allergic rhinitis and common cold. A simple drug solution is adequate for this purpose as it produces better dispersion over greater surface area. The nasal residence time of such formulation is short (3-20 min) and exhibit high inter individual variability. This route provides fast peak levels in circulation 15 Large number of drugs has been evaluated for Systemic bioavailability after transnasal administration In experimental animal models. Transnasal Administration of drugs in diverse dosage forms such As sprays, powders, and microspheres has been Attempted for improved residence and bioavailability. The nasal delivery is receiving attention for management of postoperative pain; mucosal administration requires only a 1.1-1.5 time higher

International Journal of Trend in Scientific Research and Development @ www.ijtsrd.com eISSN: 2456-6470 @ IJTSRD | Unique Paper ID – IJTSRD43868 | Volume – 5 | Issue – 5 | Jul-Aug 2021 Page 576 dose of fentanyl than i.v. dose. The nasal delivery of vaccines is a very attractive route of administration in terms of efficacy. Various Dosage Forms used: There are several delivery systems which have been used for the delivery of drugs through the nasal cavity. The selection of delivery system depends upon the drug being used, proposed indication, patient population and last but Not least, marketing preferences. Some of these delivery systems and their important features are Summarized below: Nasal drops Nasal sprays Nasal gels Nasal powders Nasal drops: Nasal drops are one of the most simple and convenient systems developed for nasal delivery. The main disadvantage of this system is the lack of the dose precision and therefore nasal drops may not be suitable for prescription products. It has been reported that nasal drops deposit human serum albumin in the nostrils more efficiently than nasal sprays. Technetium -99m- labeled human serum albumin was administered into the human nose by nasal spray or nasal drops. The results showed that about 40%of the dose cleared rapidly with average halftimes ranging from 6 to 9. Nasal sprays: Both solution and suspension Formulations can be formulated into nasal sprays. Due to the availability of metered dose pumps and Actuators, a nasal spray can deliver an exact dose from 25 to 200 µm. The particles size and morphology (for suspensions) of the drug and viscosity of the formulation determine the choice of pump and actuator assembly. Various nasal spray systems: A current trend is to Develop preservative free formulations. In a traditional Formulation basically the preservative takes care of a posssible contamination issue. An unpreserved formulation has to rely on the integrity of the primary packaging. This means in detail that the responsibility is shifted towards the manufacturer and supplier of the dispersing system. A typical example of a nasal spray system designed to administer sterile formulation. A spring loaded mechanical scaling system, which is located directly behind the small orifice in the nasal actuator, prevents through its fast opening and closing profile a possible contamination from entering the primary packaging. When dispensing out of an airtight container a vaccum will built up. In the pump system, integrated microbiological filter holds back any contamination and allows the ventilation of the package. Nasal gels: Nasal gels are high-viscosity thickened Solutions or suspensions. Until the recent development of precise dosing device, there was not much interest In this system. The advantages of a nasal gel includes The reduction of post-nasal drip due to high viscosity, reduction of taste impact due to reduced swallowing, reduction of of anterior leakage of the formulation, reduction of irritation by using soothing/emollient excipients and target to mucosa for better absorption. Entsol nasal gel: Entsol nasal gel is a drug free Hypertonic saline gel with aloe and vitamin E. It Provides soothing, moisturizing relief to dry, stuffy, irritated nasal passages. Entsol nasal gel also helps relieve nasal congestion by reducing edema and swelling, fast and effectively. It is ideal for people using CPAP machines for sleep apnea since the constant flow of air teds to dry out nasal passages. It is also very useful in dry climates of low humidity such as indoors During the winter, some of the dry western states and for individuals with nasal allergies or sinusitis. Nasal powder: This dosage form may be developed if solution and suspension dosage forms cannot be developed e.g., due to lack of drug stability. The advantages to the nasal powder dosage form are the absence of preservative and superior stability of the formulation. However, the suitability of the powder formulation is dependent on the solubility, particles size, aerodynamic properties and nasal irritancy of the active drug and/or excipients. Local application of Drug is another advantage of this system. But nasal mucosa irritancy and metered dose delivery are some of the challenges for formulation scientists and device manufacturers Evaluation of Nasal Drugs: A. vitro nasal permeation studies: Various aproaches used to determine the drug diffusion through nasal mucosa from the formulation. The two important methodologies to study the diffusion profile of the drug are discussed here, In vitro diffusion studies: The nasal diffusion cell is fabricated in glass. The water jacketed recipient chamber has total capacity of 60 ml and a flanged top of about 3mm; the lid has 3 opening, each for sampling, Thermometer, and a donor tube chamber. The 10 cm long donor chamber, and a donor tube chamber has total capacity of 60 ml and a flanged top of about 3mm; the lid has 3 openings, each for sampling, thermometer, and A donor tube chamber the 10 cm long donor chamber tube has internal

The nasal mucosa of sheep was separated from sub layer bony tissues and stoned in distilled water containing few drops at genatamycin injection. After the complete removal of blood from muscosal surface, is attached to donor chamber tube. The donor chamber tube is placed such a way that it just touches the diffusion medium in recipient chamber. At predetermined intervals, samples (0.5 ml) from recipient chamber are with draw and transferred to amber colored ampoules. The samples withdrawn are suitably replaced. The samples are estimated for drug content by suitable analytical technique. Throughout the experiment the temperature is Maintained at 37oC. A) Vivo Nasal Absorption studies Animal models for nasal absorption studies: The Animal models employed for nasal absorption studies can be of two types, viz., whole animal or in vivo model and an isolated organ perfusion or ex vivo model. These models are discussed in detail below: Rat Model: The surgical preparation of rat for in vivo Nasal absorption study is carried out as follows: The rat Is anaesthetized by intraperitoneal injection of sodium Pentobarbital. An incision is made in the neck and the Trachea is cannulated with a polyethylene tube. Another tube is inserted through the oesophagus towards the posterior region of the nasal cavity. The passage of the nasopalatine tract is sealed so that the drug solution is not drained from the nasal cavity through the mouth. The drug solution is delivered to the nasal cavity through the nostril or through the cannulation tubing. The blood samples are collected from the femoral vein. As all the probable outlets of drainage are blocked, the drug can be only absorbed and transported into the systemic circulation by Penetration and/or diffusion through nasal mucosa. Rabbit Model: The rabbit offers several advantages As an animal model for nasal absorption studies: 1. It is relatively cheap, readily available and easily Maintained in laboratory settings 2. It permits pharmacokinetic studies as with large Animals (like monkey) 3. The blood volume is large enough (approx. 300ml) 4. To allow frequent blood sampling (l-2ml) Thus it permits full characterization of the absorption and determination of the pharmacokinetic profile of a drug. Rabbits (approx. 3 kg) are either anaesthetized or maintained in the conscious state depending on the purpose of study. In the anaesthetized model, the Rabbit is anaesthetized by an intramuscular injection of A combination of ketamine and xylazine. The rabbit’s Head is held in an upright position and the drug Solution is administered by nasal spray into each Nostril. During the experiment the body temperature of the rabbit is maintained at 37°C with the help of a heating pad. The blood samples are collected by an Indwelling catheter in the marginal ear vein or artery. Dog Model: The dog is either anaesthetized or retained hi the conscious condition depending on the drug characteristics and the purpose of experiment. The dog is anaesthetized by intravenous injection of sodium thiopental and the anesthesia is maintained wiith sodium Phenobarbital. A positive pressure pump through a cuffed endotracheal tube gives the Ventilation. The body temperature is maintained at 37-38°C by a heating pad. The blood sampling is carried out from the jugular vein. Ex vivo Nasal Perfusion Models: Surgical Preparation is the same as that is for in vivo rat model. During the perfusion studies, a funnel is placed Between the nose and reservoir to minimize the loss of Drug solution. The drug solution is placed in a reservoir maintained at 37°C and is circulated through the nasal cavity of the rat with a peristaltic pump. The perfusion Solution passes out from the nostrils (through the Funnel) and runs again into the reservoir. The drug Solution in the reservoir is continuously stirred. The Amount of drug absorbed is estimated by measuring The residual drug concentration in the perfusing Solution. The drug activity due to stability problems May be lost during the course of experiment. This is Especially true for peptide and protein drugs that may Undergo proteolysis and aggregation. Rabbit can also be used as the animal model for ex vivo Nasal perfusion studies. The rabbit is anaesthetized With parenteral uretliane-acepromazine. A midline Incision is made in the neck and the trachea is Cannulated with a polyethylene neonatal endotracheal Tube. The oesophagus is isolated and ligated. The distal End of the oesophagus is closed with suture and Flexible tygon tubing is inserted into the proximal end And advanced to the posterior part of the nasal cavity. The nasopalatine tract (that connects nasal cavity to The mouth) is closed with an adhesive to avoid Drainage of drug solution from the nasal cavity. The Drug in isotonic buffer solution is recirculated using a Peristaltic pump Scintigraphic evaluation in rabbits of nasal drug Delivery systems based on carbopol 971p^® and Carboxymethylcellulose: The residence time of Apomorphine mucoadhesive preparations Incorporating ^9^9^mTc labeled

This technique was used to compare the Nasal clearance of preparations based either on Carbopol 971P^® or lactose (control), each with and Without apomorphine, or carboxymethylcellulose with Apomorphine. The planar 1-min images showed an excipient dependent progressive migration of radioactivity with time from the nasal cavity to the stomach and intestine. Thirty minutes post insufflation, the Percentages of the formulations cleared from the nasal Cavity were 47% for lactose, 26% for Lactose/apomorphine, 10% for Carbopol 971P^®, and 3% for both Carbopol 971P^®/apomorphine and Carboxymethylcellulose /apomorphine. Three hours post insufflation, the percentages of the Formulations cleared from the nasal cavity were 70% For lactose, 58% for lactose/apomorphine, 24% for Carbopol 971P^®, 12% for Carbopol971P^®/Apomorphine, and27 For Carboxymethylcellulose/ apomorphine. Apomorphine inhibited Nasal mucociliary clearance since migration of the radioactivity administered with apomorphine containing preparations was in all cases slower than that of the corresponding powder without Apomorphine. The peak plasma concentration of apomorphine was attained while all the formulations were still within the Nasal cavity. The use of mucoadhesive polymers such as carbopol 971P^® or carboxymethylcellulose in nasal dosage forms increases their residence time within the nasal cavity and provides the opportunity for sustained nasal drug delivery.
