Apperance:white powderOlopatadine hydrochloride is an antihistamine (as well as anticholinergic and mast cell stabilizer), sold as a prescription eye drop manufactured by Alcon in one of three strengths: 0.7% solution or Pazeo in the US, 0.2% solution or Pataday (also called Patanol S in some countries), and 0.1% or Patanol (also called Opatanol in some countries). It is used to treat itching associated with allergic conjunctivitis (eye allergies). A decongestant nasal spray formulation is sold as Patanase, which was approved by the FDA on April 15, 2008. It is also available as an oral tablet;

It should not be used to treat irritation caused by contact lenses. The usual dose for Patanol is 1 drop in each affected eye 2 times per day, with 6 to 8 hours between doses. Both Pazeo and Pataday are dosed 1 drop in each eye daily.

There is potential for Olopatadine as a treatment modality for steroid rebound (red skin syndrome).</sub>

Application

_{Olopatadine 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.}
