Summary

Lorlatinib is a moderate CYP3A inducer and may lower oxycodone exposure, potentially reducing analgesia. If lorlatinib is stopped, oxycodone levels may rise again and increase opioid adverse effects.

What this interaction means in plain words

Lorlatinib and Oxycodone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Lorlatinib belongs to Oncology; Oxycodone belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

Lorlatinib induces CYP3A4, increasing oxycodone's metabolism to noroxycodone.

What to do

Monitor pain control and titrate the oxycodone dose upward if needed. Reassess for sedation and respiratory depression when lorlatinib is discontinued.
