Abstract: Described herein is an improved, commercially viable and industrially advantageous process for the preparation of Repaglinide intermediate, ethyl (S)-2-ethoxy-4-[N-(1-(2-piperidino-phenyl)-3-methyl-1-butyl)-aminocarbonylmethyl]-benzoate. The process provides the Repaglinide intermediate in higher yield and purity compared to the previously disclosed processes, thereby providing for production of Repaglinide and its pharmaceutically acceptable salts in high purity and in high yield.

Abstract: Controlled-release galantamine formulations, including controlled-release particles, pellets, granules, and spheres are described. Controlled-release particles, pellets, granules, and spheres with immediate release top-coat are also described. Method of preparing such formulations and method of treating a variety of disorders are also disclosed.

Abstract: Disclosed herein are methods and compositions suitable for providing zero-order release of active agents. Disclosed herein is a multiparticulate oral dosage form comprising a plurality of pulsed-release pellets, wherein the dosage form releases the active agent at a substantially constant rate following a lag time. The dosage form comprises a combination ensemble of pellets produced by combining 2 to 8 individual ensembles of pulsed-release pellets having a particular T50 and dissolution profile.

Abstract: A multi-particulate oral dosage form, comprising a plurality of pellets, the pellets comprising a core having disposed thereon a core composition layer, the core composition layer comprising an active agent, and a sustained-release coating disposed on the core composition layer, wherein the sustained-release coating comprises a first polymer comprising a copolymer of acrylic and methacrylic esters comprising quaternary ammonium groups and having a ratio of quaternary ammonium groups to neutral meth(acrylic) esters of 1:40 and optionally a second polymer comprising a copolymer of acrylic and methacrylic esters comprising quaternary ammonium groups and having a ratio of quaternary ammonium groups to neutral meth(acrylic) esters of 1:20, wherein the ratio of the first polymer to the second polymer is about 50:50 to about 100:0, and wherein the first and second polymer comprise about 20 wt % to about 90 wt % of the total weight of the sustained-release coating; and about 10 wt % to about 50 wt % of colloidal sili

Abstract: A method of optimizing a dissolution profile for a selected active agent dosage form, comprises combining a first amount of a first ensemble of pulsed-release pellets having a first dissolution profile with a first T50 and a second amount of a second ensemble of pulsed-release pellets having a second dissolution profile with a second T50 to produce a combination ensemble of pellets having a combination dissolution profile of a combination slope, wherein the combination slope corresponds to a single phase release, and wherein the combination slope is greater than 10% lower than the slope of the first dissolution profile and greater than 10% lower than the slope of the second dissolution profile, and wherein the first ensemble of pellets and the second ensemble of pellets comprise a core having disposed thereon a core composition layer, the core composition layer comprising the active agent, and a pulsed-release coating disposed on the core composition layer.
