概要
Pyrimethamine is reported to inhibit CYP2D6, which could raise eliglustat exposure. Eliglustat can prolong PR, QTc and QRS intervals at high concentrations, so increased exposure raises arrhythmia risk.
この相互作用をわかりやすく説明すると
Eliglustat and Pyrimethamine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Eliglustat belongs to Miscellaneous; Pyrimethamine belongs to Anti Parasitic.
なぜ起こるのか
Possible CYP2D6 inhibition by pyrimethamine reduces eliglustat clearance.
対処法
Avoid if possible; otherwise reduce the eliglustat dose per labeling for CYP2D6 inhibitors and monitor the ECG. Do not combine with any CYP3A inhibitor.
