Sintesi
Ketoconazole substantially increases eliglustat exposure, which can prolong the PR, QTc and QRS intervals and cause arrhythmias. Labeling contraindicates or restricts the combination depending on CYP2D6 metabolizer status.
Cosa significa questa interazione in parole semplici
Eliglustat and Ketoconazole are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Eliglustat belongs to Miscellaneous; Ketoconazole belongs to Anti Fungals.
Perché avviene
Ketoconazole inhibits CYP3A4 and, to a lesser extent, CYP2D6, the two main pathways for eliglustat clearance.
Cosa fare
Avoid in intermediate and poor CYP2D6 metabolizers and when combined with a CYP2D6 inhibitor. In extensive metabolizers, eliglustat dose reduction is required, with ECG monitoring.
