Use
Olopatadine hydrochloride is a potent, selective antagonist of the H1 histamine receptor (Ki = 16-41.1 nM), with much lower affinities for the H2 and H3 receptors (Ki = 43.4 and 172 μM, respectively). It blocks histamine-induced phosphoinositide turnover in isolated cells (IC50 = 9.5-39.9 nM) and prevents passive cutaneous anaphylaxis in rats (ED50 = 49 μg/kg) and anaphylactic bronchoconstriction in guinea pigs (ID50 = 30 μg/kg). Olopatadine is effective in treating allergic rhinitis and conjunctivitis. It also suppresses itch in patients with well-controlled chronic urticaria. In humans, this antihistamine does not cause cognitive or psychomotor impairment at therapeutic doses.[Cayman Chemical]
