Documented Uses

• Pharmaceuticals -> Animal Drugs -> Approved in Taiwan
• Naphazoline is indicated for use as OTC eyedrops for ocular vasoconstriction or as a nasal preparation for nasal congestion.
• Drugs that selectively bind to and activate alpha adrenergic receptors.
• Drugs designed to treat inflammation of the nasal passages, generally the result of an infection (more often than not the common cold) or an allergy related condition, e.g., hay fever. The inflammation involves swelling of the mucous membrane that lines the nasal passages and results in inordinate mucus production. The primary class of nasal decongestants are vasoconstrictor agents. (From PharmAssist, The Family Guide to Health and Medicine, 1993)
• S01G - Decongestants and antiallergics
• S01GA - Sympathomimetics used as decongestants
