Abstract
A sustained release tamsulosin formulation contains tamsulosin, a hydrophobic polymer, a microsphere forming agent and a diluent. The hydrophobic polymers include pH-dependent and pH-independent polymers are used as the release-modulating agent to control the dissolution profile of tamsulosin formulation so that the formulation releases tamsulosin slowly and continuously as the formulation passed through the stomach and gastrointestinal tract. The present invention further relates to a method for preparing the sustained release tamsulosin formulation.
