概要
Ritonavir is a potent CYP3A4 inhibitor that markedly increases salmeterol exposure, leading to QT prolongation, tachycardia and arrhythmias. It also substantially raises systemic fluticasone levels, and cases of Cushing's syndrome and adrenal suppression have been reported.
この相互作用をわかりやすく説明すると
Fluticasone-salmeterol and Ritonavir 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.
Fluticasone-salmeterol belongs to Respiratory; Ritonavir belongs to Anti Virals.
なぜ起こるのか
Potent CYP3A4 inhibition by ritonavir reduces clearance of salmeterol and fluticasone.
対処法
Avoid the combination and use an alternative such as beclomethasone or another non-CYP3A4-dependent regimen. If unavoidable, monitor ECG, potassium and adrenal function.
