The primary application for phentolamine is for the control of hypertensive emergencies, most notably due to pheochromocytoma. [5]It also has usefulness in the treatment of cocaine-induced cardiovascular complications, where one would generally avoid β-blockers (e.g. metoprolol), as they can cause unopposed α-adrenergic mediated coronary vasoconstriction, worsening myocardial ischemia and ...
Trimix is a combination of three drugs: alprostadil, papaverine, and phentolamine. These medications work in combination to increase blood flow to the penis, resulting in an erection. [1] [2] [3] Alprostadil is a prostaglandin vasodilator that allows more blood to flow into the area by relaxing the smooth muscle in the blood vessels of the penis.
Nonselective alpha blockers, such as phenoxybenzamine or phentolamine, can be used to mitigate this disease. Pheochromocytoma is a disease in which a catecholamine secreting tumor develops. [ 2 ] [ 20 ] Specifically, norepinephrine and epinephrine are secreted by these tumors, either continuously or intermittently. [ 21 ]
Common examples of alpha 1 blockers are Tamsulosin, Prazosin, Phentolamine, and Phenoxybenzamine. [1] Each agent has its own off-label uses, some examples include Tamsulosin for urinary disorders, Prazosin for post-traumatic stress disorder -related nightmares and Raynaud phenomenon , Phentolamine for hypertensive crisis and extravasation of ...

Trichocereus macrogonus var. pachanoi, syn. Echinopsis pachanoi contain several phenethylamines.. Naturally occurring phenethylamines are organic compounds which may be thought of as being derived from phenethylamine itself that are found in living organisms.
Phenoxybenzamine is used as an anti-hypertensive due to its efficacy in reducing the vasoconstriction caused by epinephrine (adrenaline) and norepinephrine.Phenoxybenzamine forms a permanent covalent bond with adrenergic receptors.
