phentolamine has been researched along with Hemorrhage, Subarachnoid in 17 studies
Phentolamine: A nonselective alpha-adrenergic antagonist. It is used in the treatment of hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of RAYNAUD DISEASE and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.
phentolamine : A substituted aniline that is 3-aminophenol in which the hydrogens of the amino group are replaced by 4-methylphenyl and 4,5-dihydro-1H-imidazol-2-ylmethyl groups respectively. An alpha-adrenergic antagonist, it is used for the treatment of hypertension.
