Objective: The objective of this research was to formulate the captopril as mucoadhesive buccal films for hypertension treatment and studying the effect of different variables on the physical and mechanical behavior of the prepared films.

Methods: The bucco-adhesive patches were prepared using hydroxyl propyl methyl cellulose K4 (HPMC) as film forming a polymer with secondary polymer included carbopol 934 and eudragit RL100. The patches were prepared by a solvent casting method and evaluated for the weight variation, surface pH, mechanical properties, content, uniformity, ex-vivo mucoadhesive strength, ex-vivo permeation study and drug release study.

Results: Formula F5 containing HPMC as primary polymer with carbopol 934 as secondary polymer was chosen to be the best formulation for the following parameters: surface pH6.44, tensile strength (16.06), percentage elongation at break (34.14), swelling index(18.85), mucoadhesive strength(26.2 gm) and the folding endurance was>300 with an in vitro drug release about 94.73% during 6 h.

Fourier transforms infrared spectroscopy (FT-IR) and differential scanning calorimetric studies (DSC) showed no interaction between the drug and polymers.

Conclusion: It can be concluded that oral mucoadhesive buccal film of captopril, an antihypertensive agent can be prepared utilizing HPMC as a film forming a polymer with carbopol as a secondary polymer which extended the drug release through the buccal mucosa for 6 h.

Keywords: Captopril, Buccal patches, Hydroxyl propyl methyl cellulose and carbopol
