Phentolamine mesylate

Phentolamine Mesylate

Phentolamine Mesylate (pronunciation: fen-TOLE-a-meen MES-i-late) is a nonselective alpha-adrenergic antagonist used in the treatment of hypertension and pheochromocytoma, as well as in the diagnosis of pheochromocytoma. It is also used to prevent or control hypertensive episodes in patients with catecholamine-secreting tumors.

Etymology

The term "Phentolamine" is derived from the Greek words "phentos" meaning "visible" and "lamine" meaning "layer". "Mesylate" is derived from "mesyl", an abbreviation for methanesulfonic acid, and "-ate", a suffix used in chemistry to denote a salt or ester of an acid.

Usage

Phentolamine Mesylate is used to control blood pressure in certain adrenal gland tumor (pheochromocytoma) patients. It is also used to reverse the effects of excessive catecholamines (hormones produced by the adrenal glands) in the body.
