Pharmacodynamic properties

Alpha-given tool for local application. It has a vasoconstrictive effect. Oxymetazoline causes vasoconstriction of the mucous membranes of the nose, paranasal sinuses and Eustachian tube, which leads to a decrease in their edema and the release of nasal breathing in allergic and / or infectious-inflammatory rhinitis (runny nose).

Due to the presence of excipients in the composition of the drug (MCC, sodium carmellose and povidone K29–32) Afrin® nasal spray does not flow out of the nose and does not flow down the throat, because after being injected into the nasal passages, the spray becomes more viscous and is held on the nasal mucosa more effectively than a standard aqueous solution.

According to clinical studies, the drug begins to act within 1 min, and the action lasts up to 12 hours.

Pharmacokinetic properties

When used as a nasal spray, oxymetazoline is practically not detected in the blood plasma.
