Pharmacology :

Xylometazoline is used for its vasoconstrictor properties, acting as a ?2-agonist.  It produces a rapid and prolonged vasoconstriction lasting for up to 8-12h. It is used as a topical agent on the nasal mucosa, to produce nasal decongestion. Prolonged use of xylometazoline on the nasal mucosa may produce rebound vasodilatation (drug-induced rhinitis). This may be due to inhibition of the release of norepinephrine from vasomotor adrenergic nerve endings through an action on the presynaptic ?-receptors. Given topically in small doses, xylometazoline has no systemic effects in adults, although it is note worthy that the hypotensive effect of clonidine, which has a similar action, was first noted when the drug was under trail as a nasal decongestant.

Pharmacokinetic Actions

Little information is available concerning the absorption, distribution, metabolism and elimination of xylometazoline in humans. Absorption into the nasal mucosal tissues is rapid.

However, because of the low dose required and the local application site, other systemic side effects are minimal. Systemic absorption may occur following nasal application of xylometazoline hydrochloride solutions. It is not used systemically.


Xylometazoline is used for the temporary relief of congestion or stuffiness in the nose caused by hay fever or other allergies, colds, or sinus trouble.
