Overview

Oxymetazoline hydrochloride, an imidazoline-derivative sympathomimetic amine, is a vasoconstrictor.

Oxymetazoline hydrochloride, an imidazoline derivative sympathomimetic amine, is a vasoconstrictor. Oxymetazoline hydrochloride is a highly selective alpha1A-adrenergic agonist and partially selective alpha2A-adrenergic agonist. Topical application of oxymetazoline cream appears to reduce erythema through direct vasoconstriction.

Oxymetazoline is thought to act by targeting alpha-adrenergic receptors present in the smooth muscle sheath encasing the vessel wall of superficial cutaneous blood vessels.

Following topical administration of oxymetazoline (approximately 0.3 g of cream containing 3 mg of oxymetazoline hydrochloride to the entire face) to adults with erythema associated with rosacea, plasma concentrations of the drug were measurable in most patients. Following application of the first dose, the mean peak plasma concentration of oxymetazoline was 60.5 pg/mL. Following once daily application of the drug for 28 days in these patients, the mean peak plasma concentration was 66.4 pg/mL.

In vitro data show that oxymetazoline is 56.7-57.5% bound to plasma proteins. In vitro studies indicate that oxymetazoline is minimally metabolized by hepatic microsomal enzymes. The excretion of oxymetazoline following topical application has not been determined in humans.

USES: This medication is used to treat a certain skin disorder known as rosacea. It works by narrowing the blood vessels in the face. Oxymetazoline belongs to a class of drugs known as a sympathomimetic (alpha receptor agonist).

It may help to decrease facial redness caused by rosacea.
