Antiplatelet that is effective and inexpensive treatment for suppressing platelet aggregation- has low dose therapy of 81mg or baby - action: inhibit cyclooxygenase, an enzyme needed by platelets to synthesize thromboxane A2 (TxA2)- use: Prevention of MI and thromboembolism, prevention and treatment of stroke Source link
