ABSTRACT

The main objective of the present study was to improve the bioavailability of naproxen and decrease the frequency of dosage form administration by mucoadhesive drug delivery system. Naproxen is an NSAIDS belonging to the class non selective cox-2 inhibitor, well known to cause gastrointestinal disorders and renal effects when given orally. A buccal patch for systemic administration of naproxen in oral cavity were developed using polymers chitosan, sodium alginate, Gelatin, in order to deliver the drug to the particular region of the body for extended period of time, maximizing the drug availability, minimize the adverse effects, avoiding the first pass metabolism and thereby improving patient compliance. The formulated patches were evaluated for Mass uniformity and thickness uniformity, folding endurance, Drug content uniformity, Measurement of surface PH, Swelling index, Tensile strength, bioadhesion test, In vitro residence time, In vitro membrane permeation studies. Drug polymer compatibility studies were carried out by FTIR. & shows drug is compatible with polymers. The in vitro drug releases and in-vitro drug permeation studies showed that drug was released from the patches and permeated through the porcine buccal mucosa and hence the formulated buccal patches possibly permeate through the human buccal membrane also.
