Olopatadine eye drops are a medication used to relieve symptoms associated with allergic conjunctivitis, a condition characterized by inflammation of the conjunctiva (the thin, transparent layer covering the white part of the eye and the inner surface of the eyelids) due to an allergic reaction. Here’s some information about olopatadine eye drops:

Active Ingredient: Olopatadine is the active ingredient in olopatadine eye drops. It belongs to a class of medications known as antihistamines. Olopatadine works by blocking the action of histamine, a substance in the body that is released during an allergic reaction and causes symptoms such as itching, redness, swelling, and tearing of the eyes.

Mechanism of Action: Olopatadine blocks the effects of histamine at histamine receptor sites in the eyes, thereby reducing the allergic response and alleviating symptoms of allergic conjunctivitis.
