The first candidates are PA32540, containing 325 mg of aspirin, and PA8140, containing 81 mg of aspirin. Both products are a coordinated-delivery tablet combining immediate-release omeprazole (40 mg), a proton pump inhibitor, layered around a pH-sensitive coating of an aspirin core. This novel, patented product is administered orally once a day and an indication will be sought for use for the secondary prevention of cardiovascular disease in patients at risk for aspirin-induced gastric ulcers.
Proposed PA Indications and Usage (Pending FDA Review and Approval)
PA8140/PA32540 Tablets contain 81 mg or 325 mg delayed release aspirin and 40 mg immediate-release omeprazole and are indicated for patients who require aspirin (1) to reduce the combined risk of death and nonfatal stroke in patients who have had ischemic stroke or transient ischemia of the brain due to fibrin platelet emboli, (2) to reduce the combined risk of death and nonfatal MI in patients with a previous MI or unstable angina pectoris, (3) to reduce the combined risk of MI and sudden death in patients with chronic stable angina pectoris, (4) in patients who have undergone revascularization procedures (CABG, PTCA) when there is a pre-existing condition for which aspirin is already indicated, and to decrease the risk of developing gastric ulcers in patients at risk for developing aspirin-associated gastric ulcers.
Controlled studies with PA8140/PA32540 Tablets do not extend beyond 6 months.
About Cardiovascular Disease
Patients with established coronary heart disease or cerebrovascular disease have a high risk of a subsequent cardiovascular event including myocardial infarction (MI), stroke and death from cardiovascular disease. For such patients, lifestyle changes and drug therapy are of proven benefit and will improve outcomes. Coronary artery disease is caused by atherosclerosis and often develops into angina pectoris and MI. The condition caused about 445,000 deaths in 2005 and remains the leading single cause of death in America today. Roughly 16.8 million people have a history of MI and/or angina. An estimated 24 million have been identified as secondary prevention patients (post-event). It is estimated that cardiovascular disease causes one in every three deaths in the United States. Every 25 seconds, someone in the United States will suffer a coronary event. About every minute, someone will die from one.
