Abstract

Metoprolol succinate, β1- selective adrenergic receptor- blocking agent used in the management of hypertension, angina pectoris, cardiac arrthymias, myocardial infarction, heart failure, hyperthyroidism. In present investigation an attempt was made to reduce the frequency of dose administration to prevent nocturnal attack and to improve the patient compliance by developing to a sustained release formulation of Metoprolol succinate, the tablet was prepared by the direct compression method using different polymer with different concentration Ethyl Cellulose, HPMCK4M. Metoprolol Succinate and polymer compatibility interaction was investigated by using FTIR spectroscopy and DSC. The powder blends evaluated for precompression parameter, and tablet were subjected to post compression parameter. Also in vitro release studies upto the 12 hrs. Mathematical model in which Zero order, Higuchi model, First Order, Korsmeyer-peppas model. Formulation was optimized on the basis of acceptable tablet properties and in vitro drug release. The release kinetic of the optimized formulation F5 followed by Higuchi model and non fickian transport. Design the sustained release matrix tablet formulation of Metoprolol succinate and elucidate the release behaviour was most successful formulation of the study using direct compression process.
