Summary

Mifepristone can increase oliceridine concentrations through CYP3A4 inhibition. This may cause deeper sedation and respiratory depression, and stopping the inhibitor may lead to reduced analgesia.

What this interaction means in plain words

Mifepristone and Oliceridine 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.

Mifepristone belongs to Endocrine; Oliceridine belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

Inhibition of CYP3A4-mediated oliceridine metabolism by mifepristone.

What to do
