摘要
Chloramphenicol can inhibit CYP3A4 and may increase conivaptan concentrations, raising the risk of overly rapid sodium correction and osmotic demyelination. Conivaptan is contraindicated with strong CYP3A inhibitors, but chloramphenicol's inhibition is less well characterized.
用白話說明這項交互作用的意義
Chloramphenicol and Conivaptan 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.
為什麼會發生
Inhibition of CYP3A4 by chloramphenicol decreases conivaptan metabolism.
處置方式
Avoid the combination where possible; if used, monitor serum sodium frequently and watch for overcorrection.
