Abstract
Boswellia seratta (BS) is the best herbal medicine to treat Rheumatoid Arthritis (RA), due to its anti-inflammatory and anti-arthritic activity. Delivering BS through an oral drug delivery system has been in effective, because of its enzymatic degradation within the Gastro-Intestinal (GI) tract. In this paper, we develop a gastro retentive approach for delivering BS to avoid high hepatic first pass metabolism and optimized buccal patch based on the drug delivery characteristics. There are seven different formulated buccal films of BS that were prepared by the solvent casting method, using mucoadhesive polymers, Poly Vinyl Alcohol (PVA), and Sodium Carboxy Methyl Cellulose (SCMC). These with drug formulation can be represented as PCB. The prepared films were evaluated by various physicochemical properties and characterization studies. Results obtained from physico-chemical properties, in-vitro and ex-vivo studies among all seven patches, PCB5 shows better drug-releasing characteristics. This was further confirmed by FT-IR and XRD characterization studies. Also, the data was statistically analysed using Analysis of Variance (ANOVA).
