Check result:
Clopidogrel Bisulfate <> PCE Dispertab
Relevance: 19.10.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Talk to your doctor before using erythromycin and clopidogrel. This combination may reduce the effects of clopidogrel. Call your doctor promptly if you have any signs of blood clots such as chest pain, shortness of breath, sudden loss of vision, or pain, redness or swelling in an extremity. You may need a dose adjustment or special test if you take both medications. It is important that you tell your healthcare provider about all other medications that you are using including vitamins and herbs. Do not stop using your medications without talking to your doctor first.

Professional:

MONITOR: The concomitant administration of some macrolide antibiotics may reduce the metabolic activation of the prodrug clopidogrel and its antiplatelet effects. The proposed mechanism is inhibition of CYP450 3A4 enzymatic activity, which is responsible for the conversion of clopidogrel to its active metabolite. After coadministration of erythromycin stearate 250 mg four times a day and clopidogrel 75 mg/day to healthy subjects (n=9), the percent platelet aggregation was 42% with clopidogrel alone, 55% with clopidogrel plus erythromycin, and 93% at baseline. After coadministration of single doses of troleandomycin 500 mg and clopidogrel 450 mg, the percent platelet aggregation was 45% with clopidogrel alone, 78% with clopidogrel plus troleandomycin, and 93% at baseline. Clarithromycin also inhibits CYP450 3A4 activity and is also expected to affect clopidogrel metabolism.

MANAGEMENT: Until more information is available, monitoring for altered efficacy of clopidogrel may be advisable if a macrolide is coadministered with clopidogrel. Azithromycin and dirithromycin do not inhibit CYP450 3A4 and are theoretically not expected to interact with clopidogrel.
