Inclusion complexes of glipizide and a nonionic surfactant with cyclodextrin and cyclodextrin derivatives. A method of preparing the inclusion complexes of glipizide and a nonionic surfactant with cyclodextrin and cyclodextrin derivatives, by wetting cyclodextrin or a derivative thereof with a nonionic surfactant, and mixing the resulting mixture with glipizide. A pharmaceutical composition containing an inclusion complex of glipizide and a nonionic surfactant with cyclodextrin and cyclodextrin derivatives, in combination with pharmaceutically acceptable excipients.

Glipizide-cyclodextrin inclusion complexes and their pharmaceutical composition

An inclusion complex of bupropion hydrochloride with beta cyclodextrin that stabilizes the bupropion hydrochloride against degradation. A method of preparing an inclusion complex of bupropion hydrochloride with beta cyclodextrin that stabilizes the bupropion hydrochloride against degradation. A novel stabilized sustained-release pharmaceutical composition of bupropion hydrochloride containing an inclusion complex of bupropion hydrochloride with beta cyclodextrin. A method of preparing a novel stabilized sustained-release pharmaceutical composition containing an inclusion complex of bupropion hydrochloride with beta cyclodextrin.

Cyclodextrin stabilized pharmaceutical compositions of bupropion hydrochloride

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.
