Olanzapine for Opioid Craving and Misuse in Cancer Pain

This study is testing whether a medication called olanzapine can help reduce opioid craving and misuse in people who are taking opioids for cancer pain. Olanzapine is a drug already used for other conditions. You might be able to join if you are 18 or older, have cancer pain, are currently taking opioids, and show signs of opioid misuse. The main goal is to see if olanzapine helps lower opioid craving. Researchers will also look at how it affects opioid misuse, the amount of opioids used, pain levels, and overall symptoms. The study aims to enroll 87 participants.

Study design
