Etilefrine

Etilefrine is a cardiovascular drug, specifically a cardiac stimulant used in the treatment of hypotension. It is classified as a sympathomimetic amine, a type of drug that mimics the actions of the sympathetic nervous system.

Pharmacology

Etilefrine acts primarily on alpha-1 and beta adrenergic receptors, leading to an increase in blood pressure and heart rate. It is a direct-acting sympathomimetic, meaning it directly stimulates these receptors without the need for the body's natural neurotransmitter, norepinephrine.

Medical Uses

Etilefrine is used in the treatment of hypotension, a condition characterized by abnormally low blood pressure. It can be used in both acute and chronic cases, and is particularly useful in treating orthostatic hypotension, a type of low blood pressure that occurs when standing up from a sitting or lying position.

Side Effects

As with all medications, etilefrine can cause side effects. These may include palpitations, tachycardia (rapid heart rate), hypertension (high blood pressure), and angina pectoris (chest pain).

Contraindications

Etilefrine should not be used in patients with hypertrophic cardiomyopathy, a condition characterized by thickening of the heart muscle, as it can exacerbate the symptoms. It is also contraindicated in patients with pheochromocytoma, a rare tumor of the adrenal glands that can cause high blood pressure.
