Naphazoline

Pharmacological properties

naphazoline has a pronounced vasoconstrictor effect on peripheral vessels due to its effect on α-adrenergic receptors. when applied to the mucous membranes it reduces edema, hyperemia, exudation, which helps to facilitate nasal breathing in rhinitis. nafazolin promotes the opening and expansion of the excretory ducts of the sinuses and Eustachian tubes, which improves the outflow of secretion and prevents the sedimentation of bacteria.

The therapeutic effect occurs within 5 minutes and lasts 4-6 hours with intranasal use.
