AFRIN

Oximetazoline is an imidazoline derivative. It exhibits sympathomimetic activity and specifically stimulates the α-adrenergic receptors of the sympathetic system. When administered topically to the nose it causes vasoconstriction of the expansed arterioles of the mucosal nose and a concurrent reduction in blood flow. It also reduces the hypersecretion of the nasal mucosa, ultimately contributing to the decongestion of the nasal mucosa.
