Abstract
A sustained release system for Sumatriptan designed to increase its residence time in the stomach without contact with the Microspheres was achieved through the preparation of floating Microspheres by the Modified Emulsion solvent Diffusion method. In the present study attempt has been made to develop sustained released drug delivery system by formulating the floating Microspheres of Sumatriptan using White Rice Flour powder as a natural polymer which is biodegradable, biocompatible, nontoxic, economically cheap cost, devoid of adverse and side effects and easily availability. Sumatriptan Succinate is the succinate salt form of sumatriptan, a member of the triptan class of compounds with anti-migraine property. Sumatriptan succinate selectively binds to and activates serotonin 5-HT1 receptors. The 12 batches of floating Microspheres (MF1 to MF12) were formulated by Modified Emulsion solvent Diffusion method using different ratio of polymers like White Rice Flour power, HPMC K4M and Carbopol. The formulated Microspheres were evaluated by means of different parameters like shape and density of Microsphere, drug content uniformity, In-vitro buoyancy, swelling Index, In-vitro dissolution studies. The formulation MF6 has better sustained release when compared other formulations, hence we conclude that the combination of White Rice Flour powder, HPMC K4M shows better Gastric retention time which sustains the release of the dosage form.
