A nasal vasoconstricting decongestant drug which acts by binding to the same receptors as adrenaline. It is applied as a spray or as drops into the nose to ease inflammation and congestion of the nasal passageways. It binds alpha-adrenergic receptors to activate the adrenal system which causes systemic vasoconstriction, thereby easing nasal congestion. |

indication
It is used for treating nasal congestion and minor inflammation due to allergies or colds.
pharmacology
Xylometazoline is a direct acting sympathomimetic adrenergic alpha-agonist used to induce systemic vasoconstriction, thereby decreasing nasal congestion. The sympathomimetic action of xylometazoline constricts the smaller arterioles of the nasal passages, producing a prolonged (8-12 hours) decongesting effect.
mechanism of action
Xylometazoline is a direct acting sympathomimetic drug, which acts on alpha-adrenergic receptors in the arterioles of the nasal mucosa. This activates the adrenal system to yield systemic vasoconstrction. In producing vasoconstriction, the result is a decrease in blood flow in the nasal passages and consequently decreased nasal congestion.
