Acute Coronary Syndrome (ACS)
: Anclog Plus 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.

Dosage & Administration

The recommended dose of Clopidogrel is 75 mg once daily with or without food. No dosage adjustment is necessary for elderly patients or patients with renal patients. For patients with acute coronary syndrome (unstable angina/non-Q-wave MI), Clopidogrel should be initiated with a single 300 mg loading dose and then continued at 75 mg once daily. Aspirin (75 mg-325 mg once daily) should be initiated and continued in combination with Clopidogrel. In studies it was found that most patients with acute coronary syndrome also received heparin acutely.

Anclog Plus is generally well tolerated.

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.
Pharmacokinetics
: After repeated 75-mg oral doses of Clopidogrel (base), plasma concentrations of the parent compound, which has no platelet inhibiting effect, are very low and are generally below the quantification limit (0.00025 mg/L) beyond 2 hours after dosing. Clopidogrel is extensively metabolized by the liver. The main circulating metabolite is the carboxylic acid derivative, and it has no effect on platelet aggregation. It represents about 85% of the circulating drug-related compounds in plasma. Following an oral dose of 14C-labeled Clopidogrel in humans, approximately 50% is excreted in the urine and approximately 46% in the faeces in the 5 days after dosing. The elimination half-life of the main circulating metabolite is 8 hours after single and repeated administration. Administration of Clopidogrel with meals did not significantly modify the bioavailability of Clopidogrel as assessed by the pharmacokinetics of the main circulating metabolite.
Absorption and Distribution
: Clopidogrel is rapidly absorbed after oral administration of repeated doses
of 75 mg Clopidogrel (base), with peak plasma levels (3 mg/L) of the main circulating metabolite occurring approximately 1 hour after dosing. The pharmacokinetics of the main circulating metabolite are linear (plasma concentrations increased in proportion to dose) in the dose range of 50 to 150 mg of Clopidogrel.
Absorption is at least 50% based on urinary excretion of Clopidogrel-related metabolites. Clopidogrel and the main circulating metabolite bind reversibly in vitro to human plasma proteins (98% and 94%, respectively). The binding is nonsaturable in vitro up to a concentration of 100 g/mL.
Metabolism and Elimination
: In vitro and in vivo, Clopidogrel undergoes rapid hydrolysis into its carboxylic acid derivative. In plasma and urine, the glucuronide of the carboxylic acid derivative is also observed.
