Xylometazoline
Xylometazoline is an imidazoline derivative with sympathomimetic and nasal decongestant activity. Xylometazoline works by binding to alpha (α)-adrenergic receptors to cause vasoconstriction of nasal blood vessels.  Xylometazoline is available in over-the-counter (OTC) nasal sprays or drops to temporarily relieve nasal congestion due to cold, hay fever or other respiratory allergies. In some countries, it is available as combination products with [ipratropium], [domiphen], or [dexpanthenol].
