Abrégé
(EN)
The present invention relates to controlled release pharmaceutical compositions of tamsulosin or its pharmaceutically acceptable salts thereof. More particularly, the invention relates to a controlled release individual unit or multiple unit formulation comprising a spherical core obtained by adding release controlling agent to a mixture of tamsulosin and spheronizing agent.
(FR)
La présente invention concerne des compositions pharmaceutiques de tamsulosine, ou de sels acceptables d'un point de vue pharmaceutique de celle-ci, à libération contrôlée. L'invention concerne, plus particulièrement, une formulation à libération contrôlée unitaire ou à multiples unités, comprenant un noyau sphérique, et obtenue par addition d'un agent de contrôle de libération à un mélange de tamsulosine et d'un agent de sphéronisation.
