Bamethan (butyl-sympatol or vasculat) is an adrenaline derivative developed by C. H. Boehringer Sohn. Bamethan shows a depressor action on peripheral blood vessels as a result of the peripheral vasodilating action caused by stimulation of adrenergic beta-receptor. Bamethan has been used abroad in the treatment of certain peripheral vascular and circulatory disturbances, such as vasospastic conditions, arteriosclerotic peripheral vascular disease, Raynaud's syndrome, occlusive vascular disease of the legs, the post-thrombotic syndrome, degenerative muscular disorders, and other conditions involving peripheral vascular insuffciency.
