Cerdelga Disease Interactions

The use of drugs eliglustat should be avoided in patients with end-stage renal disease (estimated creatinine clearance (eCrCl) less than 15 mL/min not on dialysis or requiring dialysis). No dosage adjustment is recommended in patients with mild, moderate, or severe renal impairment (eCrCl at least 15 mL/min). In the case of CYP450 2D6 intermediate metabolizers, or poor metabolizers, eliglustat should be avoided in those patients with any degree of renal impairment.

The use of drugs eliglustat is contraindicated in patients with moderate or severe hepatic impairment and in those patients, who are CYP450 2D6 extensive metabolizers with mild hepatic impairment and taking a strong or moderate CYP450 2D6 inhibitor due to the risk of cardiac arrhythmias from prolongation of the PR, QTc, and/or QRS cardiac intervals. This agent is contraindicated in patients who are CYP450 2D6 extensive metabolizers, intermediate metabolizers and taking a strong or moderate CYP450 2D6 inhibitor concomitantly with a strong or moderate CYP450 3A inhibitor. In the case of CYP450 2D6 intermediate metabolizers, or poor metabolizers, eliglustat is contraindicated in those patients with any degree of hepatic impairment or those taking a strong CYP450 3A inhibitor.

The use of eliglustat is contraindicated in patients who are CYP2D6 extensive metabolizers or intermediate metabolizers taking a strong or moderate CYP2D6 inhibitor concomitantly with a strong or moderate CYP3A inhibitor or those who are intermediate metabolizers or poor metabolizers taking a strong CYP3A inhibitor due to the risk of a significant increase in drug plasma concentrations. Eliglustat is predicted to cause increases in EKG intervals (PR, QTc, and QRS) at high plasma concentrations and could result in arrhythmias; therefore, its use is not recommended in patients with preexisting cardiac disease (congestive heart failure, recent myocardial infarction, heart block, arrhythmias), or long QT syndrome.
