3-Aminoalkyl derivatives of thieno[2,3-b][1,4]thiazine-6-sulfonamide were prepared for evaluation as topically active ocular hypotensive agents. The compounds described were found to be excellent in vitro inhibitors of carbonic anhydrase II and in vivo to lower intraocular pressure in three rabbit models
