Summary

Lorlatinib induces CYP3A4 and may lower sufentanil exposure. Reduced analgesia may result, and in opioid-dependent patients withdrawal symptoms may appear. If lorlatinib is later stopped, sufentanil levels may rise and increase the risk of opioid toxicity.

What this interaction means in plain words

Lorlatinib and Sufentanil sl 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.

Evidence level: Moderate

Why it happens

Lorlatinib induces CYP3A4, increasing the metabolism of sufentanil.

What to do

Monitor analgesic response and withdrawal signs while both drugs are used, and titrate sufentanil as needed. After lorlatinib is discontinued, watch for sedation and respiratory depression and reduce the opioid dose if required.
