Bethanidine
Bethanidine
Bethanidine (pronunciation: be-tha-ni-dine) is a pharmacological agent primarily used in the treatment of hypertension. It is classified as a sympatholytic drug, which means it inhibits the postganglionic functioning of the sympathetic nervous system.
Etymology
The term "Bethanidine" is derived from the Greek words "bethane" meaning life and "idine" meaning like. This is in reference to its life-saving properties in the treatment of hypertension.
Pharmacology
Bethanidine works by blocking the transmission of nerve impulses in the sympathetic nervous system. This results in a decrease in blood pressure by reducing the amount of norepinephrine available to stimulate the adrenergic receptors.
