Formulation and evaluation of verapamil hydrochloride transmucosal drug delivery system

چکیده
Verapamil hydrochloride is an antihypertensive agent which undergoes extensive first pass metabolism making it a possible candidate for buccal delivery. Verapamil mucoadhesive buccal patches were prepared using hydroxypropyl methylcellulose, Eudragit RL 100, sodium carboxymethyl cellulose and carbopol. The physicochemical interactions between verapamil and physical mixture were investigated by Fourier transform infrared spectroscopy and differential scanning calorimetry. Results revealed no interaction between drug and polymers. The patches were evaluated for various physicochemical parameters, in vitro release studies and ex vivo permeation through porcine buccal mucosa. Residual solvent content in patches was determined by gas chromatography and are largely below the tolerated limits. The formulations showed an extended release of the drug upto period of 12 hours during ex vivo permeation studies and showed non-Fickian drug release. Stability of the optimized formulation was investigated as per ICH guidelines and was found to be stable with respect to drug content and ex vivo permeation.
