Sintesi
Conivaptan is a CYP3A4 substrate and clarithromycin markedly increases its exposure. This may lead to excessive aquaresis, overly rapid sodium correction, and a risk of osmotic demyelination. Labeling contraindicates strong CYP3A4 inhibitors.
Cosa significa questa interazione in parole semplici
Clarithromycin and Conivaptan 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.
Perché avviene
Clarithromycin inhibits CYP3A4 and reduces conivaptan clearance.
Cosa fare
Do not coadminister; use an alternative antibiotic and monitor serum sodium closely during conivaptan therapy.
Cosa chiedere al farmacista
