Patanase
® (
olopatadine nasal spray) is a prescription medication approved to treat sneezing, runny or stuffy nose, and nasal itching (known medically as rhinitis) caused by seasonal
allergies in adults and children ages 12 years and older.
Patanase is made by Alcon Laboratories, Inc.
Allergies occur when the immune system reacts to a normally harmless substance -- one that does not bother most people. This reaction is partly caused by the release of histamine from certain cells, known as mast cells. Patanase is an antihistamine nasal spray that works by preventing histamine from binding to histamine receptors. Since histamine is responsible for many of the symptoms of allergies, blocking histamine can be very helpful.
Patanase has been evaluated in studies for treating nasal allergies. In these studies, the medicine helped decrease nasal
allergy symptoms more than a placebo nasal spray (a spray without the active ingredient). Studies have shown that, unlike most steroid nasal sprays, it begins to work very quickly, as soon as within 30 minutes.
