摘要
Erythromycin raises pitavastatin exposure, which increases the risk of statin-related myopathy and, rarely, rhabdomyolysis. The effect is clinically relevant mainly in patients with renal impairment or other risk factors.
用白話說明這項交互作用的意義
Erythromycin and Pitavastatin 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.
Erythromycin belongs to Anti Bacterial; Pitavastatin belongs to Cardiovascular.
為什麼會發生
Inhibition of OATP1B1-mediated hepatic uptake of pitavastatin by erythromycin, increasing systemic statin concentrations.
處置方式
Limit pitavastatin to the labeled maximum dose with erythromycin, or use a non-interacting antibiotic or temporarily hold the statin. Advise patients to report unexplained muscle pain or weakness and check CK if symptoms occur.
