Oxymetazoline is an imidazoline derivative acting as a selective alpha-1 adrenergic receptor agonist and partial alpha-2 agonist, used primarily as a topical decongestant for nasal congestion and, more recently, in topical creams for rosacea and eye drops for redness. It is approved for current clinical use as a nasal spray, ophthalmic solution, and topical dermatological preparation.
Pharmacokinetics
Pharmacokinetic parameters estimated for a typical adult after topical (cutaneous) administration; no specific published human PK data found for this cutaneous route. Values are estimated from related nasal/ophthalmic human data and animal data, extrapolated for cutaneous application.
