Formulation and Evaluation of Mucoadhesive Buccal Tablets of Carvedilol
Abstract
The aim of the study was to formulate and evaluate the carvedilol buccal tablets using HPMC K4M and xanthan gum as polymer. Buccal tablets of carvedilol were prepared by direct compression technique by using polymer in combination at different concentration. Drug excipient compatibility study indicates that there is no interaction between the excipient and the drug. Total seven batches were prepared and subjected to evaluation parameters. Pre-compression parameters for all batches showed excellent flow propertied of powder bled. Prepared buccal tablets were evaluated for various post compression parameters like hardness, thickness, weight variation, drug content, and friability, % swelling index, muco-adhesive strength and in vitro drug release. The harness of all batches was optimum showed good mechanical strength; thickness of tablets was uniform in all formulations the weight variation test of all the formulation was found to be within the limits of pharmacopoeial standard. % swelling index for all the batch formulation was optimum and seen to increase with increase in polymer concentration. Mucoadhesive strength was also showed acceptable results for all batch formulations which satisfy the need of mucoadhesive tablets. The in vitro dissolution profile of all the formulation showed sustained release of drug, for extended periods of time. The optimized formulation of F4 prepared with was consider as the optimized formulation with respect to drug content, % swelling index, Mucoadhesive strength and in vitro drug release pattern for 8 hrs. Formulation F4 showed highest 98.32±1.55 % drug release at the end of 8 hrs. Optimized formulation F4 was found to be stable during the stability studies for 3 month indicating good stability of the formulation.
