Xylometazoline is a local vasoconstrictor (decongestant) with an alpha2-adrenomimetic effect, which manifests itself:
- narrowing of the blood vessels of the nasal mucosa;
- reduces blood flow in the venous sinuses, thus eliminating the edema and hyperemia of the nasal mucosa and nasopharynx;
- reduces the amount of secreted secretion and restores patency of the nasal passages;
- facilitates nasal breathing in rhinitis;
The action comes in a few minutes and lasts for several hours.
