Summary

Ketoconazole inhibits CYP3A4 and may impair CYP2D6 clearance routes of oliceridine, increasing opioid exposure. This may lead to respiratory depression and sedation, and stopping the inhibitor later can reduce opioid effect.

What this interaction means in plain words

Ketoconazole 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.

Ketoconazole belongs to Anti Fungals; Oliceridine belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

Inhibition of CYP3A4 (and possibly CYP2D6) reduces oliceridine metabolism.

What to do

Monitor closely for respiratory depression and sedation, dose less often and titrate carefully; reassess the dose when the inhibitor is stopped.
