Phentolamine mesylate(CAT: I004463) is a nonselective alpha-adrenergic antagonist. It works by blocking the alpha-adrenergic receptors, which are responsible for the constriction of blood vessels. By blocking these receptors, phentolamine mesylate causes relaxation of the smooth muscles in blood vessel walls, leading to vasodilation and increased blood flow. It is primarily used in the management of conditions such as hypertension, pheochromocytoma (a tumor of the adrenal gland), and certain types of erectile dysfunction.
