MedKoo Cat#: 329873 | Name: Antazoline HCl
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Antazoline is a 1st generation antihistamine with also anticholinergic properties used to relieve nasal congestion and in eye drops, usually in combination with naphazoline, to relieve the symptoms of allergic conjunctivitis. Antazoline is an ethylenediamine derivative with histamine H1 antagonistic and sedative properties. Antazoline antagonizes histamine H1 receptor and prevents the typical allergic symptoms caused by histamine activities on capillaries, skin, mucous membranes, and gastrointestinal and bronchial smooth muscles.
