Abstract

The colonic region of GIT has become an increasingly important site for drug delivery and absorption. This site specific delivery of drug to lower parts of the GIT is advantage for localized treatment of several colonic disease like colon cancer, crohn’s disease, ulceratice colitis, IBD, diarrhea etc. colon targeted drug delivery system (CTDDS) ensure direct treatment at the disease site and avoiding the systemic side effects. It is suitable for absorption site for protein and peptide drugs. Cytochrome P450 3A class of drug metabolizing enzyme, have lower activity in colon.  This review, mainly compares the primary approaches for (CTDDS) Colon targeted Drug Delivery system namely prodrugs, pH and time dependent systems, and microbially triggered systems, which achieved limited success and had limitations as compared with newer CDDS namely pressure controlled colonic delivery capsules, CODESTM, and osmotic controlled drug delivery which are unique in terms of achieving in vivo site specificity, and feasibility of manufacturing process.

Abstract

Matrix tablets of Prednisolone were prepared by wet granulation method using various proportions of Sterculia gum with Carbopol 934P and Sterculia gum with Ethyl cellulose at 1:1, 1: .5 and 1:2 ratio. Coating was carried out by using 1:1 ratio of Eudragit L100 and Eudragit S100. All the preparation were evaluated for Pre compressional properties, Post compressional properties and in-vitro Dissolution study in different pH buffer of 0.1N HCL ,pH 7.4 , pH 6.8 in order to mimic GIT condition. Formulation shows good results with good percentage yield.
