Ketotifen Ophthalmic Solution With Emedastine in Patients With Seasonal Allergic Conjunctivitis
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Medications available for the treatment of seasonal allergic conjunctivitis include antihistamines. These medicines block the release of histamine, a substance in the body that is released when an allergic reaction occurs. Novartis (NVS) has developed an eye drop formulation of a well tried antihistamine called ketotifen. This study will compare the efficacy and the tolerability of ketotifen eye drops with emedastine, which is a popular treatment for seasonal allergic conjunctivitis in China.
