Uses
- •
- For patients with non-ST-segment elevation ACS [unstable angina (UA)/non-ST-elevation myocardial infarction (NSTEMI)], including patients who are to be managed medically and those who are to be managed with coronary revascularization, clopidogrel bisulfate has been shown to decrease the rate of a combined endpoint of cardiovascular death, myocardial infarction (MI), or stroke as well as the rate of a combined endpoint of cardiovascular death, MI, stroke, or refractory ischemia.
- •
- For patients with ST-elevation myocardial infarction (STEMI), clopidogrel bisulfate has been shown to reduce the rate of death from any cause and the rate of a combined endpoint of death, re-infarction, or stroke. The benefit for patients who undergo primary percutaneous coronary intervention is unknown.
The optimal duration of clopidogrel bisulfate therapy in ACS is unknown.
For patients with a history of recent myocardial infarction (MI), recent stroke, or established peripheral arterial disease, clopidogrel bisulfate has been shown to reduce the rate of a combined endpoint of new ischemic stroke (fatal or not), new MI (fatal or not), and other vascular death.

Other Information
Clopidogrel bisulfate is an inhibitor of ADP-induced platelet aggregation acting by direct inhibition of adenosine diphosphate (ADP) binding to its receptor and of the subsequent ADP-mediated activation of the glycoprotein GPIIb/IIIa complex. Chemically it is methyl (+)-(S)-α-(2-chlorophenyl)-6,7-dihydrothieno[3,2-c]pyridine-5(4H)-acetate sulfate (1:1). The empirical formula of clopidogrel bisulfate is C16H16ClNO2S•H2SO4 and its molecular weight is 419.9.
The structural formula is as follows:
Clopidogrel bisulfate is a white to off-white powder. It is practically insoluble in water at neutral pH but freely soluble at pH 1. It also dissolves freely in methanol, dissolves sparingly in methylene chloride, and is practically insoluble in ethyl ether. It has a specific optical rotation of about +56°.
Clopidogrel tablets, USP 75 mg for oral administration are provided as pink, round, biconvex, film coated tablets, engraved “APO” on one side, “CL” over “75” on the other side. The tablets contain 97.875 mg of clopidogrel bisulfate, which is the molar equivalent of 75 mg of clopidogrel base.
Each tablet contains anhydrous lactose, colloidal silicon dioxide, crospovidone, methylcellulose and zinc stearate as inactive ingredients. The pink film coating contains hydroxypropyl cellulose, hypromellose, polyethylene glycol, red ferric oxide and titanium dioxide.

2.1 Acute Coronary SyndromeClopidogrel tablets can be administered with or without food [see Clinical Pharmacology (12.3)].
• For patients with non-ST-elevation ACS (UA/NSTEMI), initiate clopidogrel tablets with a single 300 mg oral loading dose and then continue at 75 mg once daily. Initiate aspirin (75 to 325 mg once daily) and continue in combination with clopidogrel tablets [see Clinical Studies (14.1)]. • For patients with STEMI, the recommended dose of clopidogrel is 75 mg once daily orally, administered in combination with aspirin (75 to 325 mg once daily), with or without thrombolytics. Clopidogrel may be initiated with or without a loading dose [see Clinical Studies (14.1)]. 2.2 Recent MI, Recent Stroke, or Established Peripheral Arterial DiseaseThe recommended daily dose of clopidogrel is 75 mg once daily orally, with or without food [see Clinical Pharmacology (12.3)].
2.3 CYP2C19 Poor MetabolizersCYP2C19 poor metabolizer status is associated with diminished antiplatelet response to clopidogrel. Although a higher dose regimen in poor metabolizers increases antiplatelet response [see Clinical Pharmacology (12.5)], an appropriate dose regimen for this patient population has not been established.
2.4 Use with Proton Pump Inhibitors (PPI)Avoid using omeprazole or esomeprazole with clopidogrel. Omeprazole and esomeprazole significantly reduce the antiplatelet activity of clopidogrel. When concomitant administration of a PPI is required, consider using another acid-reducing agent with minimal or no CYP2C19 inhibitory effect on the formation of clopidogrel active metabolite [see Warnings and Precautions (5.1), Drug Interactions (7.1) and Clinical Pharmacology (12.3)].
