Introduction
3. Why Transdermal Drug Delivery System ?
Transdermal drug delivery system is recognized as one of the most important
and reliable alternative to the oral and parenteral drug delivery system. Skin act
as reservoir system for drug.
TDDS includes the patches, gels, microemulsion, nanoparticles, liposomes,
niosomes, emulgel etc.
The NSAID’s, antifungals, antivirals drugs can be given through the TDDS.
Advantages of TDDS:
Avoidance of first pass metabolism.
Convenient and easy to apply.
Avoidance of gastro-intestinal incompatibility.
A relatively large area of application in comparison with buccal or nasal
cavity.

Human skin consist of three layers,
(1) Epidermis
Epidermis has five layers,
Stratum corneum (horny layer)
Stratum lucidum
Stratum granulosum (granular cell layer)
Stratum spinosum (spinous or prickle cell layer)
Stratum basale (basale or germinativum cell layer)
(2) Dermis
(3) Hypodermis
6. Skin as Permeability Barrier
An important element in transdermal drug delivery system is the skin itself. It act as permeability
barrier against the transdermal absorption of various chemicals and biologicals agents. Like all other
epithelium systems of the body, the prime function of the skin is to keep water and other vital
substances in the skin and restricted the entry of foreign substances.
The permeability barrier of skin is constituted of three major layers that include:
Stratum corneum ( 10 µm thick)
Viable epidermis (100 µm thick)
Papillary epidermis (100-200 µm thick)
Components of stratum corneum:

Components % Gross biochemical
compositions
Cell membranes 5 Lipids and nonfibrous proteins
Cell contents 85 Lipids ( 20%)
α – proteins (50%)
β – proteins (20%)
Nonfibrous proteins (10%)
Intercellular materials 10 Lipids and nonfibrous proteins
8. Methods of Drug Penetration

Eg. Sulfoxides, Azone, Fatty acids,
Alcohols.
Physical enhancement :-
- Ultrasound

9. Physiological factors
- Skin thickness
- Lipid content
- Density of hair follicles
- Density of sweat glands
- Skin pH
- Blood flow
- Hydration of skin
- Inflammation of skin
Physicochemical factors
- Partition coefficient
- Molecular wt. ( < 400 dalton )
- Degree of ionization
- Effect of vehicles.
9 Factors Affecting Topical Absorption
10. Rheumatoid Arthritis
Inflammation is an important nonspecific defence reaction to tissue injury caused
by pathogen or wound.
The five cardinal signs of inflammation are redness, swelling, heat, pain, loss of
function.
Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation
of the joints.
10
12. The use of transparent gel has expanded both in cosmetics and in pharmaceutical
preparations. Gels are relatively newer class of dosage form created by entrapment of
large amount of aqueous liquids in a network of colloidal solid particle.
In spite of many advantages of gels a major limitation is in the delivery of
hydrophobic drugs. So to overcome this limitation emulgels are prepared and with
their use the hydrophobic drugs are delivered.
The presence of gelling agent in the water phase converts a classical emulsion into an
emulgel.
Both o/w and w/o emulsions are used as vehicles to deliver various drugs to the skin.
Emulsion itself is a controlled release system where entrapped drug particles in
internal phase pass through the external phase to the skin and slowly get absorbed.
Internal phases act as reservoir of drug and slowly release drug in a controlled way
through the external phase to the skin. Gel forms cross linked network where it
captures small drug particles and provides its release in a controlled manner.
12
13. Due to its bioadhesive property it prolongs the contact period of medication
over the skin. Since emulgel possesses the property of both emulsions and gel,
it acts as dual control release system.
Depending on the type of emulsion used to prepare emulgel, they are referred
as macroemulgel, microemulgel, nanoemulgel.
Various categories of drug such as NSAIDS, antifungal, antibacterial, antiviral
etc. are used for preparation of emulgel.
13
14. Ideal Properties of Emulgel
being greaseless,
easily spreadable,
easily removable,
emollient,
non-staining,
longer shelf life, bio-friendly,
pleasing appearance.
14
15. Advantages15
Hydrophobic drugs can be easily incorporated into gels using emulsions.
Better stability.
Better drug loading capacity.
No intensive sonication.
Controlled release, medication can be terminated when needed.
Avoidance of first pass metabolism.
16. Disadvantages16
Drug of large particle size not easy to absorb through the skin.
Skin irritation or allergic reaction on contact dermatitis.
Occurrence of bubble during formation of emulgel.
17. Rational
Because, many widely used topical agents like ointments, creams,
lotions have many disadvantages. They are sticky in nature causing
uneasiness to the patient when applied, have lesser spreading coefficient
so applied by rubbing and they also exhibit the problem of stability.
17
18. Need for Study
Flurbiprofen belongs to the class II of the BCS system of drugs and oral
administration of Flurbiprofen is associated with severe gastric irritation
therefore to overcome this problem emulsion based gel form was formulated.
Flurbiprofen is hydrophobic in nature therefore it reports a problem of
solubility in water this can be solved by adding drug in oil phase of emulsion.
Emulgel overcomes the problems associated with emulsion (i.e. stability) and
gel (i.e. syneresis) alone.
Emulgel are alternative to the solid dispersion gel.
18
19. 19
To overcome the limitation of conventional oral and parenteral route of
drug administration.
To improve the patient compliance..
To formulate Emulgel of Flurbiprofen for topical drug delivery system.
To eliminate the drawbacks of emulsion and gel
by formulating in an Emulgel.
In-vitro drug release permeation studies through the suitable membrane
models using modified Franz-Diffusion cell.
To predict stability of the formulation by
conducting stability studies.

81. Conclusion
Following conclusions can be came forward after performing present study:
1) Amongst all formulations, emulgel prepared with Transcutol-P (2.5%), Sepineo P600 (0.25%) was
better with respect to overall product qualities.
2) Emulsion system provides solubalization of hydrophobic drug, thus imparts in enhancing availability of drug in
the formulation.
3) When emulgel was compared with the marketed gel, drug release from the emulgel was found to be increased
and prolonged. Additionally its permeation and appearance was found to be more acceptable.
4) The formulation followed Korsmeyer-Peppas kinetic model of drug release.
5) In-vitro diffusion studies showed good percent drug release for more than 8 hrs.
6) The formulated emulgel showed no irritation after performing skin irritation study using wistar albino female
rat is model.
Thus, results of the current study clearly indicate that Flurbiprofen emulgel can be a good alternative to the
conventional dosage form. However, further clinical studies are needed to assess the utility of this system. By
considering all above points it was concluded that, the objective of the present research study were achieved
successfully.
81
82. Future Outcomes
The future trends in innovations of drug delivery systems will continue to bring together different
technological disciplines and formulation aspects to create novel technologies.
The futuristic disciplines for emulgel may be,
Use of natural polymers as gelling agents for emulgel preparation.
Accessing the stability study for natural polymers.
Emulgels can be used in case of drugs which are having short half-life.
The use of nanosponges, microemulsion and nanoemulsion in emulgel for enhancing the
performance of emulgels.
Selection of packaging material for emulgels.
