Oral route of drug administration is the most preferred and convenient method of drug administration, but due to the poor solubility of drug is the major drawback for the dissolution and bioavailability of that drug. Absorption, distribution, metabolism and excretion of the drug depends on the solubility of the drug molecule. Solid dispersion is defined as dispersion of one or more active pharmaceutical ingredient in water soluble carriers at solid state to increase the dissolution of poorly water soluble drugs. Solid dispersion technique improves the dissolution rate of highly lipophilic drugs by enhancing bioavailability by means of decreasing particle size of drug, improving its wettability and forming amorphous particles of crystalline drugs. For preparation of solid dispersion carriers such as hydrophilic and hydrophobic are used. Nowadays the use of natural carriers is prepared over the synthetic carriers. Solid dispersion techniques are very effective and promising than conventional dosage forms. In this review we have mainly focused on historical background, introduction to solid dispersion, advantages and disadvantages, characterization of solid dispersion, method of preparation, applications, types of solid dispersion, carriers used in solid dispersion.

Formulation and Evaluation of Liquisolid Compacts of CarvedilolIOSR Journals
The purpose of this study is to develop a novel liquisolid technique to enhance the dissolution rate of
poorly water soluble drug Carvedilol, a BCS class II drug, which is a β-blocker, by using different excipients.
The main components of a liquisolid system are a non volatile solvent, carrier and coating materials and a
disintegrant. Liquisolid system refers to the formulations that are formed by conversion of liquid drugs, drug
suspensions or drug solution in non-volatile solvents into dry, non adherent, free flowing and compressible
powder mixture by blending with suitable carrier and coating materials. Hence the dissolution step, a prerequisite
for drug absorption, is by passed and better bioavailability of poorly soluble drug is achieved.
Liquisolid tablets of carvedilol are prepared by using PEG, PG, glycerine as non volatile liquid vehicles and
Avicel PH 101 and 102, Aerosil as carrier and coating materials respectively. Optimized formulation containing
20% drug in PEG 400, with Avicel 101 as carrier and Aerosil as coating material has shown 98.4% drug
release within 20 min which is better than marketed product (CARCA 12.5mg, Intas). The DSC and X-RD
studies are performed to investigate the physicochemical properties of formulation and drug excipient
interactions. The results are found to be satisfactory

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

Comparative Analysis of Total Corporate Disclosure of Selected IT Companies o...ijtsrd
Disclosure is a process through which a business enterprise communicates with external parties. A corporate disclosure is communication of financial and non financial information of the activities of a business enterprise to the interested entities. Corporate disclosure is done through publishing annual reports. So corporate disclosure through annual reports plays a vital role in the life of all the companies and provides valuable information to investors. The basic objectives of corporate disclosure is to give a true and fair view of companies to the parties related either directly or indirectly like owner, government, creditors, shareholders etc. in the companies act, provisions have been made about mandatory and voluntary disclosure. The IT sector in India is rapidly growing, the trend to invest in the IT sector is rising and employment opportunities in IT sectors are also increasing. Therefore the IT sector is expected to have fair, full and adequate disclosure of all information. Unfair and incomplete disclosure may adversely affect the entire economy. A research study on disclosure practices of IT companies could play an important role in this regard. Hence, the present research study has been done to study and review comparative analysis of total corporate disclosure of selected IT companies of India and to put forward overall findings and suggestions with a view to increase disclosure score of these companies. The researcher hopes that the present research study will be helpful to all selected Companies for improving level of corporate disclosure through annual reports as well as the government, creditors, investors, all business organizations and upcoming researcher for comparative analyses of level of corporate disclosure with special reference to selected IT companies.

A Study on the Effective Teaching Learning Process in English Curriculum at t...ijtsrd
“One Language sets you in a corridor for life. Two languages open every door along the way” Frank Smith English as a foreign language or as a second language has been ruling in India since the period of Lord Macaulay. But the question is how much we teach or learn English properly in our culture. Is there any scope to use English as a language rather than a subject How much we learn or teach English without any interference of mother language specially in the classroom teaching learning scenario in West Bengal By considering all these issues the researcher has attempted in this article to focus on the effective teaching learning process comparing to other traditional strategies in the field of English curriculum at the secondary level to investigate whether they fulfill the present teaching learning requirements or not by examining the validity of the present curriculum of English. The purpose of this study is to focus on the effectiveness of the systematic, scientific, sequential and logical transaction of the course between the teachers and the learners in the perspective of the 5Es programme that is engage, explore, explain, extend and evaluate.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

Design Simulation and Hardware Construction of an Arduino Microcontroller Bas...ijtsrd
This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

Disadvantages of solid dispersion
1. Due to solid dispersion the amorphous state may
undergo crystallization in commercial products
due to stress and storage conditions.
2. When solid dispersion formulation comes in
contact with moisture it tends to decrease its
storage stability thus promoting crystallization.
3. It is found that wen solid dispersion comes in
contact with the moisture it absorbs the moisture
and causes phase separation of solid dispersion,
eventually decrease it solubility and effects on
pharmacokinetic properties.
Classification of solid dispersion
Solid dispersion can be classified based on their
molecular arrangement as follows;
1. Eutectic mixture
2. Amorphous Precipitation In crystalline matrix
3. Solid solution
a. Continues solid solution
b. Discontinuous solid solution
c. Substitutional solid solution
d. Interfacial solid solution
4. Glass solution and suspension
1. Eutectic mixture: -
This mixture consists of two compound’s which are
soluble in the liquid state but has limited extent in the
solid state. This mixture is prepared by solidification
of fused melt of two compounds that are completely
miscible but negligible in solid solution.
2. Amorphous Precipitation In crystalline matrix: -
This method is same as eutectic mixture, but the drug
is precipitated out in amorphous form.
3. Solid Solution: -
Solid solution is same as liquid solution, it consists of
only one phase without considering the number of
component’s present in it. In solid solution the
particle size is reduced and hence it increases the
surface area. Solid solutions are further classified
depending on the solubility.
A. Continuous solid solution - In continuous solid
solution the components are soluble completely.
The strength between two components is stronger
than the strength between the molecule.
B. Discontinuous solid solution - In discontinuous
solid solution the miscibility of either of
component is low.
C. Substitutional solid solution - This is only
possible when the size of the molecule is less than
15 percent then the solvent molecule. Solid
solution has crystalline structure in which the
solute molecule can fit into the crystal lattice of
the solvent molecule.
D. Interstitial solid solution - The molecules fit
in to the interstitial species Within the solvent
molecule. In this, solute molecule should be
0.95 times less in diameter then that of
solvent molecular diameter.
4. Glass solution and suspension.
Glass solution are homogenous in nature that has
glassy system in which the solute dissolves in glass
carriers. Glass suspension consist of particle that are
precipitated and are suspended in glass solvent. The
lattice energy is less in suspension and glass
suspension.
Selection of carriers for solid dispersion
The dissolution rate of drug can be enhanced by
incorporating of carriers during preparation of solid
dispersion. A carrier should have followed criteria.
1. Freely water soluble, increased dissolution
properties.
2. It must be non-toxic inert
3. International Journal of Trend in Scientific Research and Development @ www.ijtsrd.com eISSN: 2456-6470
@ IJTSRD | Unique Paper ID – IJTSRD50101 | Volume – 6 | Issue – 4 | May-June 2022 Page 809
3. Thermally stable with a low melting point it must
be miscible with solvents during solvent
evaporation method
4. It must be able to enhance the dissolution of drug
in aqueous media.
5. It must be compatible with the drug and should
not form complex
Types of carriers
A. First generation carriers (crystalline carrier) –
Urea sugar and organic acids.
B. Second generation carriers (polymeric carrier)-
PEG, HPMC, PVP.
C. Third generation (surfactant or polymers)- Poloxamer 408, Tween 80, SLS.
Polymers-
1. Polyethylene glycols (PEG)- Polyethylene glycols are derivatives of ethylene oxide and have molecular
weight of 200 to 300000. PEG which has mol. wt. of 1500 to 20000are used in production of solid dispersion
usage of polyethylene glycols in solid dispersion enhances solubility in organic solvents. Addition of peg
also increases compound wettability. Drawbacks associated with Peg there are few toxicity issues related to
peg associated with excipients. PEG is low molecular weighs shows high chances of toxicity than that of
high molecular Polyethylene glycols. Polyethylene glycols does not have confirm stabilityissues during hot
melt method.
2. Polyvinyl pyrrolidine when vinyl pyrrolidone undergoes polymerization process Polyvinyl pyrrolidine is
synthesized. It has molecular weigh about 2500 to 300000. Temperature of Polyvinyl pyrrolidine depends on
two paraments, its
3. Molecular weight and moisture contents. Polyvinyl pyrrolidine has high glass transition temperature and
hence has only limited application of production of solid dispersion by hot melt method. As Polyvinyl
pyrrolidine have high solubility in various organic solvent there mostly used in solvent method as the
increasing concentration of Polyvinyl pyrrolidine not only decreases aqueous solubility but also increases it
viscosity due to high molecular weight.

Cellulose derivatives-
1. Hydroxy propyl methyl cellulose - Hydroxy
propyl methyl cellulose (HPMC) is combination
of ethyl cellulose; in that around 16.5 to 30
percent; of hydroxyl group are methylated and
about 4 percent to 32 percent; are derivatized by
use of hydroxy propyl group. HPMC molecular
weight of around 10000 to 1500000. HPMC are
miscible in water and with ethanol with
dichloromethane methanol with dichloromethane
poorly soluble acids such as nilvadipine shows
quick release by use of HPMC in solid dispersion
2. Hydroxy propyl Cellulose - Hydroxy propyl
Cellulose (HPC) has good solubility in various
solvent for eq. water, chloroform, methanol the
molecular wight of Hydroxy propyl Cellulose is
around 37000 to 11. 5000.using low molecular
weight Hydroxy propyl Cellulose as carrier in
preparation of solid dispersion thus increasing the
releases rate.
3. Carboxymethyl ethyl cellulose – Carboxymethyl
ethyl cellulose (CMEC) this belongs to the class
of cellulose ether, but under gastric condition its
dissolution rate is hampered Carboxymethyl ethyl
cellulose are readily soluble in acetone mixture of
ethanol and dichloromethane.
4. Hydroxypropyl methyl cellulose phthalate
(HPMCP) - They are commonly used as enteric
coating polymer Hydroxypropyl methyl cellulose
phthalate molecular weight ranges from 20000 to
2000000. There are various grades are available
and they dissolve at Ph of 5 or 5.5. By using co-
evaporate of HPMCP by incorporating in
Griseofulvin at Ph 6.8 it is seen that the
dissolution rate is increased.
5. Polyacrylates and polymethacrylates - These are
formed by method of polymerization of acrylic
and methacrylic acid, and also the derivatives of
nitriles and ester amides. In the field of
pharmaceutical, they are commonly used as
coating polymers to restrict the release of drug.
Like eudragit e is commonly used because it
enhances the release rate and is soluble in buffer.
6. Urea- Urea is produced as end product of protein
metabolism in human it is nontoxic. It shows high
solubility in water and also organic solvents.
When urea was used with phenytoin the release
ate f drug is enhanced by twice over, but using
PEG 6000 in this technique gives more efficient
results.
7. Sugar- Sugars, polyols and polymers- sugars
shows high solubility in water, but there are less
harmful issues. And hence they are not commonly
used as carriers. As the melting point of sugars is
more hot melt method may cause issues during
preparations. Sugars are less soluble in organic
solvents and so it is difficult to produce co-
evaporates. mannitol has melting point of 1650
C;
1680
C and hence it is used to prepare solid
dispersion by hot melt technique as it degrades at
a temperature above 2500
C.
Method of preparation of solid dispersion-
There is main two process of preparing solod
dispersion melting and solvent evaporation
1. Melting method
2. Melt agglomeration method
3. Solvent evaporation method
4. Hot melt extrusion method
5. Fusion method
6. Spray drying
7. Supercritical fluid method
8. Freeze drying
9. Co precipitation method
10. Dropping method
1. Melting method – In melting method the drug is
added in a suitable liquid solvent. This solution is
then mixed with melted polyethylene glycol
which is obtained below 700
C. by using this
method 5 to 10 percent of the liquid sample must
be added to polyethylene glycol 6000. This
method is done by preparing a mixture of drug
and water-soluble carrier with help of heating
until its melt. Then the solid mass which is
obtained is crushed and sieved.
2. Melt agglomeration method – In this method a
conventional high shear mixture is used which
allows preparation of solid dispersion by melt
agglomeration in this the drug is added to molten
carrier along with heated excipient. the mixture of
drug, carrier and excipient low heated to
temperature more than the melting point of
carrier. This technique is used where the binder
act as carrier the melt in procedure gives a
homogenous distribution of the drug.
3. Solvent evaporation method – In this technique
the drug and carrier are solubilize in a volatile
solvent by using this technique the decomposition
of drugs and carrier by heat can be prevented,
because most of the organic solvent evaporate at
low temperature. In this the drug and carrier are
mixed and dissolved in solvent such as ethanol or
chloroform.
4. Hot melt extrusion method- In this process the
component is mixed with the help of extruder
with intense pressure. An extruder consists of
barrel, hopper, Screw for kneading, Heating
jacket and die. The drug and ca solid dispersion

can also be processed continuously so that large
scale production is possible due to various shape
the product can be convenient to handle. In
solubility of drug and carrier creates an issue. The
extruder generates heats during the production
and hence the thermos labile component can be
degraded.
5. Fusion method- This method is one of the oldest
methods for the production of solid dispersion.
Previously the solid dispersion used in the field of
pharmaceutical were produced by this method.
When the starting material are in the crystalline
state it is called as melt method.
6. Spray drying method - This technique Is most
commonly used for solid dispersion. This
procedure involves solvent evaporation. In this
method the drug is suspended in the carrier and
sprayed in to the heated air flow which evaporates
the solvent. Due to lesser particle size, the surface
area is increased due to which the solvent is
evaporated and the solid dispersion ins produced
7. Supercritical fluid extraction method - This
Supercritical fluid extraction (SCF) method uses
co2 as a supercritical fluid this method is also
called as micritization method. Application of co2
removes the polymeric component from the
process. SCF are also used to decreases the
temperature during the melt dispersion procedure.
8. Freeze drying method - In this process drug and
matrix are incorporated in liquid nitrogen and is
frozen completely. This frozen solution is then
lyophilized. In freeze drying the drug is not
degraded due to heat. The major benefit of freeze-
drying process is phase separation solid
dispersion is not possible.
9. Co-precipitation method - Co-precipitation
technique is most promising method for the drugs
which less solubility and thus solubility and
bioavailability in this technique non solvent is
incorporated in drug and carrier solution by
addition of non-solvent the drug and carrier are
further precipitated which has less particle size
finally this suspension is then filtered and dried.
10. Drooping method- This technique has major
application then other various methods in this
method spherical particle are generated from
fused solid dispersion. Generally fused drug
carrier complex Is pipetted out and solidified into
spherical particle various factor influence on
shape and size of particle.
Characterization techniques are used to distinguish
between Solid solution, physical mixtures of drug and
carriers. Analytical methods that are used to
characterize solid dispersion are as follow
A. Fourier Infrared spectroscopy
B. Differential scanning spectroscopy
C. Powder x ray diffraction
D. UV-vis spectrophotometry
A. Fourier transform infrared spectroscopy
Fourier transform infrared spectroscopy (FTIR) is a
technique is carried out for identification of
functional group and identification of unknown
compounds I in various field. FTIR Shows a infrared
spectra of compound and it is used for estimation of
functional group in the sample compound or mixture
of compound like solid, liquid and gases. FTIR
consist of a infrared source, fixed mirror, beam
splitter, moving mirror, laser diode, gas ample cell
and detector. FTIR is commonly used in
pharmaceutical filed, research field, forensic
investigation, food research and biochemical and
biomedical research industry.
B. UV-vis Spectrophotometry
UV-vis spectrophotometry is a quantitative technique
which is used in the field of biochemistry. It is used to
determine species and to study the biochemical
process. This method helps us to detect micro-molar
concentration in the sample. The absorption of UV or
visible light by chemicals compound gives us a
distinct spectrum. When a compound absorbs a v
radiation transition of electrons Whitin the molecule
occurs from ground state (low electronic level) to
excited state (high electronic energy level). The
components of UV visible spectrophotometer are
source, filter or monochromator, sample holders and
detector. UV spectroscopy is used to detect impurities
in the sample, identification of sample, it is also used
for structural elucidation of organic compounds.
Quantitative determination of compounds which
absorbs UV radiation. It also has wide range of
application in the field of inorganic species, organic
compounds and proteins.
C. X-ray Diffraction
X ray diffraction technique is mainly used for
identification of nature of compounds whether present
in crystalline or amorphous form. X-ray Diffraction is
also used for structural analysis of compounds like
crystal nature, crystal habit, strain and size. X-ray
Diffraction works on Braggs equation. X rays were
introduced by W.C. roentgen in 1895. X-ray
Diffraction technique is used for determination and
identification of crystal habit and structure of
compounds. It is also used in determination of
crystallite size. This technique for both crystallin and
non-crystalline material. in general, X-ray Diffraction
is an equipment used for study of crystalline
materials. X-ray Diffraction consist of x ray source
calorimeter and photographic film it is also used for

study of qualitative and quantitate parameter’s. X-ray
Diffraction technique is widely used in
pharmaceutical industry, paint industry, Geology and
minerology.
D. Differential Scanning Calorimetry
Differential Scanning Calorimetry (DSC) it is a
thermal analysis technique in which sample is
introduced to a controlled temperature program. DSC
is commonly used for indentation of compound,
compatibility of drug compounds with excipients and
carriers. In DSC sample and reference are heated
simultaneously and temperature is increased or
decreased linearly. DSC has wide application in
various fields such as identification, purity
determination of compounds, stability-compatibility
of compounds, detection of polymorphism, detection
of isomorphism and pharmaceutical industry.
Application of solid dispersion
1. To increase the bioavailability, dissolution rate,
solubility of poorly soluble drugs.
2. To sustain instability by hydrolysis, oxidation,
recrimination, isomerization, photo oxidation and
other decomposition procedures.
3. To reduce side effect of certain drugs.
4. To mask unpleasant taste and smell of drugs.
5. To enhance drug release from formulations such
as, ointments, creams and gels.
6. To reduce incompatibilities.
7. To gain equal distribution of a small amount of
drug in solid state.
8. To produce rapid release dose in a sustained
release dosage form.
9. To prepare sustained release formulation of drugs
by using poorly soluble carriers.
10. To decrease inactivation of drug that occurs pre
systemically.
