In this study, controlled release matrix tablets containing cephelexin were prepared using HPMC15 cps and Eudragit L100 in different concentration by Direct compression method. Tablets were evaluated for physical properties,Hardness, friability, weight variation and In vitro dissolution study was carried on USP II apparetus (peddle type). The best formulations selected based on above parameters were subjected for Extend release study with use of different ratio of polymer as Eudragit and HPMC .The tablets with Eudragit were found to release drug for longer duration of time as compared to formulations containing HPMC. The drug release from the tablets was sufficiently sustained.

The purpose of this research was to prepare and characterize Aceclofenac microsphere of guar gum polymer for the application of inflammation. Method: - The microsphere were prepared by using emulsification method using starch cross-linked agent and coating was done by solvent evaporation method with the pH sensitive eudragit S-100 polymers. Result:-The prepared microsphere were white, free flowing and spherical in shape. The drug-loaded microsphere showed entrapment efficiency and drug release was extended upto 6 to 8 h. The infrared spectra, differential scanning calorimetry thermographs spectra all showed the stable character of both the drugs in the drug-loaded microspheres and revealed the absence of drug-polymer interactions. Scanning electron microscopy study revealed that the microspheres were spherical and porous in nature. The stability study was conducted to conform the stability of prepared microsphere. In-vitro drug release study was performed in both simulated gastrointestinal fluid medium and rat cecal content of different pH. Conclusion:-The prepared Aceclofenac microsphere has the potential for delaying the release of drug.

This study was to investigate the effect of formulation variables like Microcrystalline cellulose (MCC), Lactose, Dicalcium phosphate dihydrate (DCPD), Starch 1500, Pearlitol 200sd etc. which are widely used tabeleting excipients. These diluents were used individually and in combination with MCC. Binders like Hydroxypropyl cellulose (HPC-sL), Polyvinylpyrrrolidone-K 30, were used to study their effect on pellet properties. The pellets prepared were analyzed for the properties like their shape (aspect ratio), size distribution, smoothness, bulk density, tapped density, car index, hausner ratio, Loss on drying and yield.

prepare and evaluate mucoadhesive drug delivery system of Ranitidine hydrochloride tablet using hydrophilic polymers in order to reduce dose frequency to match the initial release of the drug with the conventional dosage form. The formulation was designed adopting optimization technique, which helps in setting up experiments in such a manner that the information is obtained as efficiently and precisely as possible. Initially, considering buoyancy as the main criteria, blank tablets were compressed for different formulae with various polymers HPMC K 15 M, HPMC K 100 M, Carbopol 934. The tablets were prepared by direct compression method and evaluated for Ranitdine content, in vitro release profile and buoyancy. The dissolution study was carried out in simulated gastric fluid using USP dissolution test apparatus employing paddle stirrer.. This indicates the suitability of the technique chosen for the present dosage form.

Amlodipine used as an anti-hypertensive and in the treatment of angina. FDT of amlodipine besylate were prepared using different superdisintegrants by direct compression method. Mannitol was used as a diluent. Aspartame and Acesulfame Potassium were used for unpleasant taste masked from the amlodipine by cosifting and serial of blending with other excipients. The mixed final blend was then compressed into tablets. The formulations were evaluated for weight variation, hardness, friability, wetting time, disintegrating time, dissolution, taste evaluation study and in vitro dispersion time.

The Purpose of the Present study was to compare the action of glucose and scopolamine on the cognitive function using digital zero maze apparatus on albino rats.The present study 3 groups were taken and had given treatment glucose and scopolamine (buscopan)and Normal Saline.The digital zero maze was design to study animal behavior after supervised training given to the rats.glucose and scopolamine were shows that the glucose a have some sought of cognition enhancing activity inexperiment animals On the other hand the scopolamine slows down cognition activity of brain.

Metformin matrix and gastro retentive tablets formulations were prepared with different compositions. Finally, one optimized formula for each, matrix and gastro retentive, were selected and studied in detail. The effect of formulation variables namely, process of manufacturing, different excipients, different polymers, and concentration of polymer were studied. Metformin release was inversely proportional to the polymer concentration. Drug release from the developed formulations was independent of pH of the release medium but dependent on the agitational intensity, hardness of tablet, and surface area of tablet. Metformin release from both developed matrix and gastro retentive formulations follows first order. The manufacturing procedure was found to be reproducible and formulations were stable after one month of accelerated stability studies.

The objective of this research work was to formulate and evaluate the floating drug delivery system containing Albendazole, an anthelmintic drug, using different polymers and to optimize the best formulation. Different excipients were tested for their compatibility with Albendazole by the FTIR studies. Present study has demonstrated the successful utilization of technique of FT IR to assesst he compatibility of Albendazole with the excipients used in the development of floating drug delivery system of Albendazole. Based on the results of FT-IR studies, majority of the excipients were found to be compatible with Albendazole which were then used in the preparation of Albendazole floating tablets. Albendazole tablets were prepared by wet granulation technique using HPMC, HPMC K4M and chitosan as polymers, stearic acid, citric acid, lactose and gas generating agent such as sodium bicarbonate were taken as independent variables. It was then evaluated by using USP-II (Paddle) apparatus containing 0.1 N HCl as a dissolution media. The release mechanisms of Albendazole from floating tablet were evaluated by the n value of Krosmeyer Peppas model.
