Description
|
Used to treat allergic conjunctivitis (itching eyes), olopatadine inhibits the release of histamine from mast cells. It is 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. |
| Indication |
For the treatment of ocular itching associated with allergic conjunctivitis. |

| Affected Organisms |
| • |
Humans and other mammals |
|
| Biotransformation |
The mono-desmethyl and the N-oxide metabolites have been detected at low concentrations in the urine. |
| Absorption |
Ophthalmic use of olopatadine usually does not produce measurable plasma concentrations. |
| Half Life |
3 hours |
| Elimination |
Elimination was predominantly through renal excretion. |
