Résumé
Clarithromycin markedly increases colchicine exposure, and fatal colchicine toxicity has been reported with this combination. Presentations include severe gastrointestinal symptoms, myopathy, bone marrow suppression, multiorgan failure and death. Patients with renal or hepatic impairment and older adults are at greatest risk, but toxicity can occur even at standard colchicine doses.
Ce que signifie cette interaction, en termes simples
Clarithromycin and Colchicine 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; Colchicine belongs to Genitourinary.
Pourquoi elle survient
Clarithromycin inhibits both CYP3A4 and P-glycoprotein, reducing colchicine metabolism and efflux and raising systemic levels with a narrow therapeutic index.
Conduite à tenir
Avoid the combination, and choose a non-interacting antibiotic such as azithromycin or doxycycline where clinically appropriate. If a macrolide course is essential, withhold colchicine for the duration of treatment, and in patients with renal or hepatic impairment the combination should not be used at all.
