SUSTAINED-RELEASE BUPROPION AND BUPROPION/MECAMYLAMINE TABLETS

摘要

Sustained-release bupropion hydrochloride pharmaceutical tablets and combination sustained-release bupropion hydrochloride/mecamylamine hydrochloride pharmaceutical tablets are obtained by granulating the bupropion hydrochloride with a hydroxyalkylcelluose, and blending the resulting granules within an extragranular phase composed of a particulate material that provides a sustained-release matrix, and compressing the blend into a tablet form, which then is coated, with a means to provide delayed release, such as with an enteric coating composition. The mecamylamine hydrochloride can be contained in a second granule comprising a hydroxyalkylcellulose.
