Sintesi

Benzhydrocodone is a prodrug of hydrocodone, which is metabolized by CYP3A4. Chloramphenicol may inhibit this pathway, raising hydrocodone levels and risking sedation and potentially fatal respiratory depression.

Cosa significa questa interazione in parole semplici

Benzhydrocodone / acetaminophen and Chloramphenicol 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.

Livello di evidenza: Moderate

Perché avviene

Inhibition of CYP3A4-mediated metabolism of hydrocodone, increasing its plasma concentrations.

Cosa fare

Avoid if possible or use a lower opioid dose and monitor closely for sedation and respiratory depression. Reassess the dose if chloramphenicol is stopped, since opioid levels will fall.

Cosa chiedere al farmacista
