CELECOXIB LOADED MICROBEADS: A TARGETED DRUG DELIVERY FOR COLORECTAL CANCER

Abstract

Celecoxib is a nonsteroidal anti‐inflammatory drug that exhibits anti‐inflammatory, analgesic, and antipyretic activities. Recently, considerable interest has been focused on t he use of biodegradable polymers for specialized applications such as targeted release of drug formulations; meanwhile, microbeads drug delivery systems using various kinds of biodegradable polymers have been studied extensively during the past two decades. In the present investigation, it was aimed to prepare microbead formulations of celecoxib inclusion complex using sodium alginate and eudragit FS 30‐D as a carrier for colonic administration to extend the retention of the drug in order to treat colorectal cancer. Microbead formulations were evaluated for entrapment efficiency, FT‐IR, DSC, SEM, In vitro drug release, In vitro cell line study, Cytotoxicity Screening. Formulation F5 showed 91.99 ± 1.45% entrapment, which was uniformly dispersed and having smooth surface texture in formulation,  F5 shown 92.11±2.32% drug release up to 8 hr. Coated Celecoxib microbeads (1:1ratio) showed cytotoxicity against HT‐29 cells. DNA Fragmentation study confirms the better anti cancer activity of celecoxib microbeads against human colorectal adenocarcinoma cell line HT‐29. Hence the formulations can be effectively tested for its anticancer activity.
