Olpadin 5ml Ophthalmic Solution

Indication
Olopatadine is indicated for the treatment of ocular itching associated with allergic conjunctivitis.

Pharmacology
Olopatadine is an inhibitor of the release of histamine from the mast cell and a relatively selective histamine H1?antagonist that inhibits the in vivo and in vitro type 1 immediate hypersensitivity reaction including inhibition of histamine induced effects on human conjunctival epithelial cells. Olopatadine is devoid of effects on alpha adrenergic, dopamine and muscarinic type 1 and 2 receptors. Following topical ocular administration in human, olopatadine was shown to have low systemic exposure.

Dosage
0.1% Sterile Eye Drops: One drop in each affected eye two times per day at an interval of 6 to 8 hours. 0.2% Sterile Eye Drops: One drop in the affected eye once a day.0.7% Sterile Eye Drops: One drop in each affected eye once a day.

Pregnancy
There are no adequate and well controlled studies in pregnant women. Because animal studies are not always predictive of human responses, this drug should be used in pregnant women only if the potential benefit to the mother justifies the potential risk to the fetus.It is not known whether topical ocular administration could result in sufficient systemic absorption to produce detectable quantities in the human breast milk. Nevertheless, caution should be exercised when Olopatadine Hydrochloride ophthalmic solution is administered to a nursing mother.
