PHENOTOLAMINE

Phenotolamine is a non-selective alpha-adrenergic antagonist used to manage conditions like pheochromocytoma (a type of tumor that causes high blood pressure) and to treat severe hypertension during surgical procedures. It works by blocking alpha-adrenergic receptors, which helps to lower blood pressure and improve blood flow. Phenotolamine is typically administered intravenously and requires close monitoring to manage potential side effects, such as tachycardia or orthostatic hypotension.
