Formulation and evaluation of rifampicin sustained release tablets using juice of Citrus limetta as bio-retardant

Abstract

The advantages of biopolymers over synthetic polymers are low cost, natural origin, free from side effects, biocompatible, bio-acceptable, environmental friendly processing, local availability, better patient tolerance as well as public acceptance. Sustained release tablets containing rifampicin was prepared by adding 100 mg polymer and 50 mg Drug and Granules. Same procedure was followed with 3% and 5% of polymer for preparation of sustained release tablets. Additional Tablets of 100 mg, 200 mg and 400 mg were prepared using 5% of the polymer. The results indicated that the selected biopolymer had a good release retardant property thus it can be concluded that the selected biopolymer can be utilized as low cost natural biocompatible and biodegradable agent.
