Solid dispersion is one of the vastly accepted and practically economical processes in bioavailability enhancement study. The present investigation deals mostly with increase in solubility and dissolution rate of BCS class 4 drugs for enhancement of oral bioavailability. For the same solid dispersion were prepared and analyzed for appropriate concentration of drug polymer ratio by phase solubility analysis. The solvent evaporation study widely accepted due to its efficient solid dispersion in lesser efforts. The study designs were prepared with specific concentration of drug and polymer ratio with the help of high throughput model i.e. Central Composite Design (by Design Expert trial copy) by specific design of experiment with full factorial design (DOE). The fixed variables were concentration of polymers and dependant variables were dissolution and permeability across bio-membrane in in-vitro model.

The solubility behavior of drugs remains one of the most exigent aspects in formulation development. With the advent of combinatorial chemistry and high throughput screening, the number of poorly water soluble compounds has dramatically increased. Among all the newly discovered chemical entities, about 40 45 drugs fail to reach market due to their poor water solubility. Because of solubility problem, bioavailability of drugs gets affected and hence solubility enhancement becomes necessary. In present study the attempts have been made to increase the dissolution of BCS class 2 drug Piroxicam using hydrophilic polymers namely polyethylene glycol PEG 6000 and sodium lauryl sulphate as a surfactant by using solid dispersion technique. In solid dispersion microwave induced solid dispersion and conventional fusion method is compared. Drug polymer complex was prepared using batch method. Maximum dissolution rate was obtained of the complex prepared from Piroxicam PEG6000 SLS . A successful solubility enhancement of drug complex was confirmed by taking drug release in phosphate buffer pH 6.8. The drug was characterized according to different compendial methods, on the basis of identification by UV spectroscopy, organoleptic properties and other tests. After that among the all formulation batches, solid dispersion F16 was selected for further tablet formulation batches, nine formulations were developed and studied. The values of pre compression parameters was evaluated, results were within prescribed limits and indicated good free flowing properties. The data obtained of post compression parameters such as weight variation, hardness, friability, wetting time, water absorption ratio, content uniformity, disintegration time and dissolution was found to superior over conventional formulation. The F9 batch with disintegrating time 10 ± 0.52 second and dissolution 93.20 ± 0.61 was selected as optimized formulation and was found superior over other formulation. Batch F9 was also subjected to stability studies for three months and was tested for its disintegrating time, drug contents and dissolution behavior monthly. F9 formulation after stability study was found to be stable.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

3. PREFORMULATION
Pre-formulation is a group of studies that focus on the physicochemical properties of a new drug candidate
that could affect drug performance and the development of a dosage form.
This could provide important information for formulation design or support the need for molecular modification.
Every drug has intrinsic chemical and physical properties which have been considered before development of
pharmaceutical formulation.
This property provides the framework for drugs in combination with pharmaceutical ingredients in the
fabrication of dosage forms.
The overall objective of pre formulation testing is to generate information useful to the formulator in developing
stable and bioavailable dosage forms which can be mass-produced.
POONA COLLEGE OF PHARMACY, PUNE 3
5. OBJECTIVES
To establish the Physicochemical parameters of a new drug entity.
To determine its kinetics and stability.
To establish its compatibility with common excipients.
It provides insights into how products should be processed and stored to ensure their quality.

7. Organoleptic properties of the drug:
Organoleptic properties are the aspects that can be experienced through ones senses like taste, smell, sight, and
touch.
Thus, it includes a recording of the colour,odour, and taste of the drug.
Bulk characters of the drug:
Crystallinity-Crystallinity refers to the outer appearance and internal structure of the drug molecule and can
affect its physicochemical properties.
Polymorphism is the ability of a compound to crystallize in different shapes with different internal structure.
Hygroscopicity-It is the measure of the tendency to adsorb atmospheric moisture by the drug substance. It
characterizes the drug stability with respect to the environmental humidity.
Fine particle characterization- The size of the drug particle can influence its dissolution rate, suspend ability
and other properties. Thus, it becomes important to classify the drug substances as coarse, moderately coarse,
very coarse, fine, and very fine.
Powder flow properties- Since the majority of active pharmaceutical ingredients are delivered as powders,
either as a pill or for dissolution, understanding and controlling the powder behavior of drugs are extremely
important. Powder flow properties help you understand the ease with which the drug powder will flow under a
set of specific conditions like humidity, pressure.

8. Solubility analysis
Ionization constant- pKa is the measurement of the acidity of the compound. Its determination helps in understanding the
solubility, protein binding, and permeability of the drug substance to characterize its properties like absorption, distribution,
metabolism and excretion from the body.
pH solubility profile helps to understand the influence of pH on drug solubility, stability, and absorption.
Common ion effect (Ksp) determines the solubility of the drug substance when a soluble compound having a common ion
with the drug is added to the test solution.
Thermal effects help to evaluate the drug solubility with respect to the changes in the temperature of the solvent.
Solubilization is the method of increasing the solubility of sparingly soluble drug substance by various techniques like
adding a co-solvent, changing the pH and temperature, adding a surfactant, reducing the particle size etc.
Partition co-efficient is the measurement of the drug lipophilicity or ability to cross a cell membrane.
Dissolution is the process of resolving the drug substance into its individual components and characterizing their properties.
Stability analysis
The stability of the drug is studied with respect to various factors like-
Solution stability
pH-rate profile
Solid state stability
Bulk stability
Compatibility

14. SeDeM diagram is based on the quality by design (QBD) described in ICH Q8 .since it evaluates
critical quality attributes that have impact on the final product quality.
The SeDeM diagram expert system provides the profile of excipients and API in powder form
with the respect to their suitability for direct compression.
Three numerical forms are
• IGCB –Index for good compressibility and bucCo dispersibility.
• IP – Index Parameter
• IPP – Index Profile Parameter
Index parameter (IP) = NP≥5/ NPt
where , NP≥5 = number of parameters with a value equal or higher than 5.
NPt = Total number of parameters studied.
The acceptability limit would correspond to IP ≥5
SEDEM STUDIES
POONA COLLEGE OF PHARMACY, PUNE 14
15. Index Profile Parameter (IPP) = mean r of all parameters studied.
The acceptance limit is IPP = Mean r ≥ 5.
Index of Good Compressibility and Bucco dispersibility (IGCB) is calculated as follows i.e.,
IGCB =IPP *f
where , f- reliability factor and is calculated by
f= polygon area / circle area
The acceptance limit is IGCB ≥ 5
NOTE that IGC and IGCB are not same

20. SeDeM – ODT expert system for CBD and co processed excipients :
21. SeDeM – ODT expert system for disintegrants:
22. Taking into consideration the results obtained using the SeDeM-ODT diagrams, the API and possible excipients
that could be used for developing orodispersible tablets were evaluated.
IGCB showed us that the best excipients that could be used to obtain orodispersible tablets were PODTG2 and
PETsp, also LCT and CELMC presented good IGCB values.
From the two co-processed excipients PODTG2 needs just one improvement represented by the taste, while if
PETsp is used to obtain ODT, a sweetener and a flavour should be added to the composition.
Fast disintegration represents another critical parameter. The possibility of using a mixture of super disintegrants
could improve this property.
In the end, we can conclude that from an analytical point of view each excipient could be used to obtain ODTs but
from a pharmacotechnical point of view, some of the excipients need improvement.
