| Hazard Information | Back Directory | [Chemical Properties]
Phentolamine mesylate (65-28-1) is a white, odourless powder which is soluble in water and alcohol. | [Uses]
An adrenergic blocking agent. An antihypertensive. Used for the treatment of pheochromocytoma. | [Uses]
Phentolamine Mesylate is a nonselective alpha-adrenergic antagonist with IC50 of 0.1 μM | [Brand name]
Regitine
(Novartis) [Name previously used: Phentolamine Methanesulfonate.]. | [General Description]
Phentolamine Mesylate(65-28-1) belongs to the class of alpha adrenergic antagonist drugs. It is used in the treatment of pheochromocytoma-related hypertension, erectile dysfunction and in the diagnosis of pheochromocytoma and norepinephrine-related dermal necrosis. | [Biochem/physiol Actions]
α-Adrenergic receptor antagonist; peripheral vasodilator. | [Clinical Use]
Alpha-adrenoceptor blocker:
Hypertensive crisis | [Safety Profile]
Poison by intravenous and subcutaneous routes. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of SOx and NOx. | [Drug interactions]
Potentially hazardous interactions with other drugs
Anaesthetics: enhanced hypotensive effect.
Antidepressants: additive hypotensive effect with
MAOIs - avoid.
Antihypertensives: enhanced hypotensive effect.
Avanafil, vardenafil, sildenafil and tadalafil: enhanced
hypotensive effect - avoid concomitant use.
Diuretics: enhanced hypotensive effect.
Linezolid: additive hypotensive effect.
Moxisylyte: possibly severe postural hypotension. | [Metabolism]
Phentolamine is extensively metabolised.
Only about 10-13% of an intravenous dose is excreted
unchanged in the urine, and the fate of the remainder of
the drug is unknown. | [storage]
Store at +4°C | [Mode of action]
Phentolamine Mesylate is the mesylate salt of a synthetic imidazoline with alpha-adrenergic antagonist activity. As a competitive alpha-adrenergic antagonist, phentolamine binds to alpha-1 and alpha-2 receptors, resulting in a decrease in peripheral vascular resistance and vasodilatation. This agent also may block 5-hydroxytryptamine (5-HT) receptors and stimulate release of histamine from mast cells. |
