Comment: the addition of drugs that induce this enzyme (such as rifampin, phenobarbital, and phenytoin) or inhibit this enzyme (such as ketoconazole, erythromycin, and saquinavir) could increase the levels of parent drug or its active metabolites in a patient that was previously at steady-state, and this could potentially precipitate serious arrhythmias, including torsade de pointes
