P2Y12 receptor inhibitor therapy in 7 days before HCR surgery.\n22. Nonselective non-steroidal anti-inflammatory drugs (NSAIDs) and prostacyclins (PGI2) therapy that cannot be stopped\n23. Increased risk of bradycardic events (eg, no pacemaker and known sick sinus syndrome, second degree atrioventricular block, third degree atrioventricular block or previous documented syncope suspected to be due to bradycardia).\n24. Concomitant oral or intravenous therapy (see examples below) with strong CYP3A inhibitors, CYP3A substrates with narrow therapeutic indices, or strong CYP3A inducers within 14 days of study treatment or cannot be stopped for the course of the study.\n\n Strong inhibitors: ketoconazole, itraconazole, voriconazole, telithromycin, clarithromycin, nefazadone, ritonavir, saquinavir, nelfinavir, indinavir, atanazavir, over 1 litre daily of grapefruit juice.\n\n Substrates with narrow therapeutic index: cyclosporine, quinidine. Strong inducers: rifampin/rifampicin, phenytoin, carbamazepine.
