Abstract
Background: At present, pharmaceutical researchers are focusing on instantaneous intraoral dispersible technologies as novel drug delivery systems because of their outstanding advantages over the traditional oral and parenteral routes of drug administration. Most essential natural drugs have low oral bioavailability due to extensive first pass metabolism and pre systemic degradation in the GIT. Purpose of Study: This research intends to addresses these problems by formulating a cheap, intraoral rice paper Intraoral Dispersible Film (IDF). IDFs are potent and could improve bioavailability of natural drugs. Methods: In this study, formulation was optimized using the experimental factorial design. The IDFs were loaded with model natural anticancer drugs Resveratrol and Curcumin with low oral bioavailability. They were evaluated for thickness, folding endurance, swelling behavior because these relate to drug release properties. Permeation was also evaluated using the pig mucosal membrane mounted on a Franz diffusion cell, and taste testing was done to determine acceptability using a taste panel. Results: Sixteen formulations showed variations in disintegration time, thickness, tensile strength and permeation profiles. My key finding is, ex vivo release profiles of the optimized formulation revealed first order release and later zero order. Conclusions: Therefore, it is evident that rice paper IDF could efficiently deliver natural drugs into the blood.
