Pharmacology

Olopatadine is a histamine H1antagonist that reduces the type 1 acute hypersensitivity reaction in vivo and in vitro, including reduction of histamine produced effects on human conjunctival epithelial cells. The alpha adrenergic, dopamine, and muscarinic type 1 and 2 receptors are all unaffected by olopatadine.

Interactions

May result in additive CNS depression with CNS depressants.

Contraindications

Side-Effects

Headache has been reported at an incidence of 7%. The following adverse experiences have been reported in less than 5% of patients: asthenia, blurred vision, burning or stinging, cold syndrome, dry eye, foreign body sensation, hyperemia, hypersensitivity, keratitis, lid edema, nausea, pharyngitis, pruritus, rhinitis, sinusitis and taste perversion.

Pregnancy & Lactation

There were 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 embryo or 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 ophthalmic solution is administered to a nursing mother.
