Indication
Oxymetazoline Hydrochlorid is indicated for the treatment of nasal congestion associated with acute or chronic rhinitis, common cold, sinusitis, upper respiratory allergies, epistaxis and hay fever. It is also used as nasal decongestant in otitis media.
Pharmacology
Oxymetazoline Hydrochloride is an imidazoline derivative sympathomimetic amine. It is a direct agonist at ?ñ-adrenoceptors but has no action on ?ý- adrenoceptors. It is used as a topical agent on the nasal mucosa, produces a rapid and long acting vasoconstriction of the arterioles, thus reducing the blood flow and diminishing swelling of the mucosa. This results in improved potency of the airway and better drainage of the nasal sinus.
