Olopatadine hydrochloride
Olopatadine hydrochloride (/ˌɒləˈpætədiːn ˈhaɪdrəˌklaɪd/) is a type of antihistamine and mast cell stabilizer used in the treatment of allergic conjunctivitis and allergic rhinitis (hay fever). It is available in two forms: as an ophthalmic solution and a nasal spray.
Etymology
The name "Olopatadine" is derived from its chemical structure, which is a derivative of the benzocycloheptene class of antihistamines. The suffix "-dine" is common in drugs that have antihistamine properties. The term "hydrochloride" refers to the hydrochloride salt form of the drug, which is commonly used in pharmaceuticals to improve the drug's stability and absorption.
Pharmacology
Olopatadine hydrochloride works by blocking the action of histamine, a substance in the body that causes allergic symptoms. It also stabilizes mast cells, which are cells that release histamine and other substances during an allergic reaction.
Uses
Olopatadine hydrochloride is used to relieve symptoms of allergic conjunctivitis such as redness, itching, and watering of the eyes. It is also used to relieve symptoms of allergic rhinitis such as sneezing, runny nose, and nasal itching.
