Abstract
A tamsulosin controlled release tablet is formed using a water-swellable matrix-forming composition as a release controlling mechanism. The matrix forming composition comprises (i) a pH-sensitive swellable hydrophilic polymer, which is a cross-linked polyacrylic acid polymer, and (ii) a pH-insensitive swellable hydrophilic polymer. The tablet optionally contains a water insoluble binder as well.
