Abstract: One aspect of the invention resides in a monolithic sustained release composition of glipizide for patients with non-insulin dependent diabetes mellitus that exhibits a breakdown after ingestion by a patient in conformity with a zero-order kinetic. The present invention provides a composition of a glipizide and a hydrocolloid forming agent and optimally other auxiliary excipients for the sustained release of glipizide. It is preferable that the hydrophilic material comprises at least 50% by weight of the composition. The present invention is also directed to the process for producing the composition. One aspect of this process includes the steps of granulating glipizide, a hydrophilic material and a diluent, drying the granulated product and lubricating the product with a flow regulating agent and lubricant.
