Silostazol ve Omeprazol etkileşimi

CYP2C19 Substrates (e.g., clopidogrel, citalopram, cilostazol, phenytoin, diazepam) Clopidogrel Clinical Impact: Concomitant use of omeprazole 80 mg results in reduced plasma concentrations of the active metabolite of clopidogrel and a reduction in platelet inhibition [see Clinical Pharmacology ( 12.3 )].

Cilostazol Clinical Impact: Increased exposure of one of the active metabolites of cilostazol (3,4-dihydro-cilostazol) [see Clinical Pharmacology ( 12.3 )] .

Intervention: Reduce the dose of cilostazol to 50 mg twice daily.

See prescribing information for cilostazol.

Strong and moderate CYP3A4 and CYP2C19 inhibitors: Increase exposure to cilostazol.

Inhibitors of CYP3A4 or CYP2C19 Inhibitors of CYP3A4 Coadministration of strong (e.g., ketoconazole) and moderate (e.g., erythromycin, diltiazem and grapefruit juice) CYP3A4 inhibitors can increase exposure to cilostazol.

Inhibitors of CYP2C19 Coadministration with CYP2C19 inhibitors (e.g., omeprazole) increases systemic exposure of cilostazol active metabolites.

Reduce cilostazol dose to 50 mg twice daily when coadministered with strong or moderate inhibitors of CYP2C19 [see Dosage and Administration ( 2.2 ) and Clinical Pharmacology ( 12.3 )].
