概要
Berotralstat inhibits P-gp and CYP3A4, both involved in quinidine disposition, and can increase quinidine levels. Quinidine may also raise berotralstat via P-gp inhibition. Elevated quinidine exposure increases the risk of QT prolongation and arrhythmia, and berotralstat itself prolongs QT at higher doses.
この相互作用をわかりやすく説明すると
Berotralstat and Quinidine 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.
Berotralstat belongs to Miscellaneous; Quinidine belongs to Anti Parasitic.
なぜ起こるのか
Berotralstat inhibits P-gp and CYP3A4, reducing quinidine clearance, while quinidine inhibits P-gp efflux of berotralstat.
対処法
Monitor ECG QTc and quinidine concentrations, and reduce the quinidine dose if levels or QTc rise; consider an alternative antiarrhythmic.
