Design and Development of Buccal Mucoadhesive Drug Delivery System for Perindopril
Jordan Journal of Pharmaceutical Sciences(2015)
Abstract
The main objective of present study was to develop a buccal mucoadhesive drug delivery system for perindopril. Perindopril buccal mucoadhesive patches were developed by solvent casting technique using hydroxy propyl methylcellulose (HPMC), polycarbophil, sodium carboxymethylcellulose (SCMC) and sodium alginate as polymers for extended release of perindopril. Glycerine and DMSO were used as plasticizer and penetration enhancer respectively. Ethanol, methanol and dichloromethane were used as solvents. FTIR and DSC studies revealed no interaction between drug and polymers. The drug content in the perindopril patches was found to be uniform. The films exhibited good physical and mechanical properties. The surface pH of all the patches was within salivary pH range. Residual solvent content in patches are below the tolerated limits. The patches were found to have an extended release of the drug upto a period of 12 hours during ex vivo permeation studies with non-Fickian diffusion mechanism. The present study demonstrated the possibility of designing a buccal drug delivery system for perindopril.
