Abstract

Objective: The present study is to achieve colon-specific targeted delivery of oxaliplatin for the treatment of colon cancer and also to assess the use of Guar Gum, Locust Bean Gum, Chitosan alone and also with combination of Hydroxy propyl methyl cellulose (HPMC) in the form of a compression-coating on oxaliplatin core tablet.

Methods: The core tablet of 20 mg of Oxaliplatin was coated with various proportions of Guar Gum (GG), Locust Bean Gum (LBG), Chitosan (CS) and HPMC K-100 as a compression coating material. The effects of these polysaccharides, its level and the coat thickness were evaluated. All the batches were subjected for its potential in colon-specific drug delivery by conducting drug release studies in simulated gastric and intestinal fluids. The amount of oxaliplatin released from the compressed coated tablets at different time intervals was estimated by a UV Spectroscopy method.

Results: From the experimental studies the tablets coated with above mentioned coating materials alone with combination of polysaccharides have showed sustained drug release in the colonic environment. In vitro drug release studies was known to follow super case transport- II.

Conclusion: This study indicated that the use of polysaccharides that are biodegraded by colonic microflora could result in comparatively safer and more effective delivery of drugs to the colon and also a new means to achieve colon-specific drug delivery. This study also revealed that this approach prevents the oxaliplatin drug release in the upper gastrointestinal environment.
