Phentolamine CAS 50-60-2

Phentolamine is an alpha adrenergic receptor blocker. Clinically used for vascular spasticity diseases, such as acroarterial spasm (i.e., Raynaud's disease), cyanosis of hands and feet, infection toxic shock and pheochromocytoma diagnostic tests, for ventricular premature beat is also effective.
Physical and chemical properties
White or white like crystalline powder; Odorless, bitter taste. Soluble in water or ethanol, slightly soluble in trichloromethane.

The α-receptor is selectively blocked and the α-type effect of epinephrine is antagonized, but the effect is weak.

1. Blood vessels: Intravenous injection can reduce blood vessel dilation, blood pressure, pulmonary artery pressure and peripheral vascular resistance. Its mechanism is mainly the direct relaxation of blood vessels, and large doses also appear to block the α receptor.
2. 2. Heart: has an exciting effect on the heart, strengthens the cardiac contractility, accelerates the cardiac Chemicalbook rate, and increases the output. This excitatory effect is partly caused by vasodilation, blood pressure drop, reflex; It is partly the result of blocking the α2 receptor in the presynaptic membrane of nerve endings, thereby promoting the release of norepinephrine. It can occasionally induce arrhythmia.
3. 3. Others: It has a cholinergic effect and excites gastrointestinal smooth muscle. With histamine-like effect, increase gastric acid secretion, skin flushing and so on.
