摘要
Ritonavir is a strong CYP3A4 inhibitor, and paritaprevir adds to this effect, which reduces lidocaine clearance. Systemic lidocaine concentrations can rise, causing CNS toxicity and arrhythmia. The label advises caution with antiarrhythmics given with this regimen.
用白話說明這項交互作用的意義
Lidocaine and Ombitasvir / paritaprevir / ritonavir and dasabuvir 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.
為什麼會發生
