Phentolamine Chemical Properties,Uses,Production

Uses

Anti-adrenergic.

Definition

ChEBI: 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 fo the treatment of hypertension.

Indications

Human erectile tissue has a population of membrane receptors that are predominantly of the -adrenoceptor subtype. Phentolamine (Vasomax) is a nonselective - adrenoceptor blocking agent (see Chapter 11), and like other such agents, it has been used to treat ED. Nonselective adrenoceptor antagonists may provoke a reflex that increases both sympathetic outflow and the release of norepinephrine.

brand name

Regitine (Novartis) [Name previously used: Phentolamine Methanesulfonate.].

General Description

Phentolamine isthe more effectiveα -blocker.

Clinical Use

Phentolamine isused to prevent or control hypertensive episodes that occurin patients with pheochromocytoma. It also has been used incombination with papaverine to treat impotence.

Clinical Use

Phentolamine has been used orally and intracavernosally in the treatment of ED. Following oral administration, phentolamine has a plasma half-life of about 30 minutes and a duration of action of 2 to 4 hours. An intracavernosal injection of phentolamine results in the drug reaching maximum serum levels in about 20 to 30 minutes. It is rapidly metabolized. Phentolamine has been used in combination with papaverine, chlorpromazine, and vasoactive peptides in the treatment of ED.

Side effects

Side effects of phentolamine are dose related. It may cause orthostatic hypotension, reflex tachycardia, cardiac arrhythmias, and rarely, myocardial infarction. Phentolamine also may reduce sperm motility in vitro.

Enzyme inhibitor

This versatile nonselective a-adrenergic receptor antagonist (FWfree-base = 281.36 g/mol; CAS 50-60-2 (free base), 65-28-1 (mesylate salt), and 73-05- 2 (mono-HCl salt, which is slightly soluble in water (1 g/ 50 mL water) ), known systematically as 3-[4,5-dihydro-1H-imidazol-2-ylmethyl- (4- methylphenyl) amino]phenol, has been used to treat hypertension, hypertensive emergencies, pheochromocytoma, vasospasm associated with Reynaud’s Disorder and frostbite. The methanesulfonate salt is also known as Regitine?. Note: Aqueous solutions are unstable and must be freshly prepared and cannot be stored. Target (s) : a-adrenergic receptor; K+- channels, ATP-sensitive, or KATP channels); and protein kinase C.
