摘要
Ritonavir substantially increases colchicine exposure, and life-threatening or fatal colchicine toxicity has been reported. Toxicity may include severe gastrointestinal illness, rhabdomyolysis, pancytopenia and multiorgan failure. The combination is contraindicated in patients with renal or hepatic impairment and requires major dose reduction in others.
用白話說明這項交互作用的意義
Colchicine 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.
Colchicine belongs to Genitourinary; Ritonavir belongs to Anti Virals.
為什麼會發生
Ritonavir is a potent CYP3A4 and P-glycoprotein inhibitor, which markedly reduces colchicine clearance.
處置方式
Do not combine in patients with renal or hepatic impairment. In patients with normal organ function where co-administration cannot be avoided, follow the labeled markedly reduced colchicine dosing and avoid repeating flare treatment for several days.
