Researchers at WSU’s College of Veterinary Medicine are seeking 13 healthy cats to help study whether the antacid, omeprazole, reduces the effectiveness of clopidogrel (Plavix®).  Clopidogrel is commonly used in both human and animal medicine to prevent blood clots. Recent studies in both humans show that omeprazole reduced the blood-thinning effects of clopidogrel, increasing the risk for heart attacks. Since it is not uncommon for cats with heart disease to have coexisting conditions that require treatment with omeprazole, the purpose of this study is to determine if there is an interaction between the two medications in cats.

Cats must be: healthy, 2-8 years of age, and weigh at least 9 pounds.

Owners need to: give their cat medications on a prescribed schedule, fill out a medication log, and transport their cat to WSU Veterinary Teaching Hospital for blood draws and physical examinations on seven separate occasions.
