Patients will undergo a complete history including a medication history for intake of ASA/NSAIDs/anticoagulants/antiplatelet agents, physical examination, complete blood count, complete metabolic profile, ECG's and chest x-rays which rule out an exclusionary illness. Female subjects will have a urine pregnancy test performed. They will then sign an informed consent to participate in this randomized, double-blind study protocol. Patients will be excluded if they are currently using acid suppressive therapy or if they have a history of gastric/duodenal ulcers or gastroesophageal reflux disease that has required acid suppressive therapy.
