The main objective of work was to develop pharmaceutically elegant and stable enteric coated tablet formulation for highly unstable drug in acidic environment using pH dependent polymer. Development of Enteric coated tablets were done for Controlled Release of drug. Coating was done by using methacrylic acid copolymer (Eudragit L 100). Characterization of Drug and Excipients was carried out including compatibility studies of drug and excipients. Solid dispersion of glimepiride was formulated using carrier PEG20000 was prepared by the Fusion method. Evaluation of Solid was carried out using suitable parameters like solubility, percentage yield, drug content, in-vitro drug release, FTIR and SEM. Further granules were formulated from the optimized batch of formulated SDs. Pre-compression studies of granules were carried out like Tapped density, Bulk density, Angle of repose, etc. of Granules. Four different batches were formulated of tablets. The tablets were evaluated for various parameters like weight variation, hardness, friability, thickness, disintegration and in-vitro drug release. For Dissolution studies, 7.4 phosphate buffer media was used. The optimized batch of tablets was further subjected to enteric coating using pan coating. Eudragit L100 was used as coating polymer and isopropyl alcohol, acetone and triethyl citrate were used as vehicle in solution. Eosine was used as colorant. The coating solution was prepared in three different concentrations viz., 1%, 2%, and 3%. The coating solution was sprayed on tablets using spray gun and after drying the tablets were evaluated for different parameters like in-vitro drug release and disintegration, Hardness, thickness, friability, drug content and weight variation. Here, as the tablet was enteric coated, 2 dissolution medias were used 7.4 phosphate buffer and 0.1 N HCl. Further Stability studies were carried out of optimized batch. Results obtained after the stability studies confirmed that prepared enteric coated tablets were stable at applied conditions and were complied with the initial results.Keywords

A major challenge in the drug development and delivery process is improving aqueous solubility and rate of dissolution of drugs, which ultimately improves absorption of the drug. Bicalutamide is most useful drug in prostate cancer treatment it is a non-steroidal antiandrogen. It comes under class of poorly water-soluble drug. Poor water-solubility of drugs leads to slow drug absorption, and low bioavailability, for which its solubility is to be enhanced to improve the oral bioavailability of the. One of the possible way to overcome this outcome is to use formulate solid dispersion by using spray drying technique. Spray-drying is a unit operation by which a liquid product is atomized in a hot gas current to instantaneously obtain a powder. The purpose of this research was to improve the solubility profile of Bicalutamide by spray drying technique using Methanol and Polyvinyl pyrolidone-K30. Prepared solid dispersions were evaluated for drug release profile. The compatibility was studied by Fourier Transforms Infrared spectroscopy (FTIR). Prepared Microspheres were subjected to various physicochemical evaluations and in-vitro dissolution profile. The effects of different concentrations of polymer on Solubility enhancement were studied.Keywords

The aim of the present study was to enhance the dissolution rate of poorly water soluble drug, Bicalutamide. Bicalutamide is an antiandrogen agent used in the treatment of prostate cancer. To improve the dissolution rate of the drug, hydrophilic carriers like povidone K30 was and methanol was used for preparing microspheres. Microspheres of Bicalutamide were prepared by spray drying technique by using povidone K 30 at different concentrations. The microspheres were evaluated for drug release profile. The compatibility was studied by Fourier Transforms Infrared spectroscopy (FTIR). Prepared Microspheres were subjected to various physicochemical evaluations and in-vitro dissolution profile. The effects of different concentrations of polymer on Solubility enhancement were studied. The microspheres were compressed into tablets, and different tableting parameters were investigated. The dissolution profile of the tablets was also evaluated and compared with the marketed product. From the dissolution profile, it was observed that the carrier ratio of 3:1 of magnesium aluminum silicate to povidone K 30 exhibited higher dissolution rate than the other formulations.Keywords
