Resumo
Clarithromycin is a strong CYP3A4 inhibitor, and lovastatin depends almost entirely on CYP3A4 for clearance. Exposure rises many-fold, leading to myopathy and rhabdomyolysis.
O que esta interação significa em palavras simples
Clarithromycin and Lovastatin 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.
Clarithromycin belongs to Anti Bacterial; Lovastatin belongs to Cardiovascular.
Por que acontece
CYP3A4 inhibition by clarithromycin reduces first-pass and systemic clearance of lovastatin
O que fazer
Do not combine; choose an alternative to clarithromycin or a statin that is not CYP3A4-dependent such as pravastatin or rosuvastatin, withholding the statin if the macrolide is essential.
