Olopatadine Hydrochloride

Indications

Olopatadine Nasal Spray is an H1 receptor antagonist used to treat the symptoms of seasonal allergic rhinitis in adults and children aged 6 and above.

Pharmacology

Olopatadine, an antihistamine, decreases allergy symptoms by inhibiting the activity of histamine in the body. Olopatadine Hydrochloride is used to treat allergy symptoms such as sneezing, itching, runny nose, and other nasal symptoms. Olopatadine Nasal Spray is made up of 0.6 percent w/v Olopatadine (base) in a nonsterile aqueous solution with a pH of around 3.7. Following the first priming (5 sprays), each metered spray from the nasal applicator provides 100 microliters of aqueous solution containing 665 mcg of olopatadine Hydrochloride, which is comparable to 600 mcg of Olopatadine (base). In addition to benzalkonium chloride (0.01 percent), dibasic sodium phosphate, edetate disodium, sodium chloride, hydrochloric acid and/or sodium hydroxide (to adjust pH), and filtered water, Olopatadine Nasal Spray includes.
