Administration

The recommended oral dose is one tablet daily.

Effects

This combination is generally well tolerated.

Clopidogrel overdose may lead to bleeding complications. Based on biological plausibility, platelet transfusion may restore clotting ability. In moderate aspirin intoxication dizziness, headache, tinnitus, confusion, and gastrointestinal symptoms may occur which can be treated by inducing vomiting followed by gastric lavage if needed. In severe Aspirin intoxication respiratory alkalosis respiratory acidosis, metabolic acidosis, hyperthermia, perspiration, dehydration can occur. It can be treated with haemodialysis and other symptomatic treatment.

Indications

Acute Coronary Syndrome (ACS): It is indicated to reduce the rate of Myocardial Infarction (MI) and Stroke in patients with non-ST-segment elevation ACS [unstable angina (UA)/non-ST-elevation Myocardial Infarction (NSTEMI)] and acute ST-segment elevation ACS [ST-elevation Myocardial Infarction (STEMI)].

Recent MI, recent Stroke, or established Peripheral Arterial Disease: In patients with established peripheral arterial disease or with a history of recent Myocardial Infarction (MI) or recent Stroke it is indicated to reduce the rate of MI and Stroke.

Pharmacology

Clopidogrel is a prodrug. It inhibits platelet activation and aggregation through the irreversible binding of its active metabolite to the P2Y12 class of ADP receptors on platelets. Dose-dependent inhibition of platelet aggregation can be seen at 2 hours after single oral doses. Repeated doses of 75 mg per day inhibit ADP-induced platelet aggregation on the first day, and inhibition reaches steady state between Day 3 and Day 7.

Aspirin inhibits platelet aggregation by irreversible inhibition of platelet cyclooxygenase and thus inhibiting the generation of thromboxane A2 a powerful inducer of platelet aggregation and vasoconstriction.

Precautions

This combination may prolongs the bleeding time.
Thrombotic thrombocytopenic purpura (TTP): TTP has been reported rarely following use of this combination.
Reye's syndrome: Reye's syndrome may develop in individuals who have chicken pox, influenza or flu symptoms. Hypersensitivity including rash, angioedema or hematologic reaction has been reported in patients receiving this combination or history of hypersensitivity to other thienopyridines
