OBJECTIVE：To provide reference for rational use of opioids analgesics. METHODS：1 882 prescriptions of opioids analgesics for cancer pain collected from our hospital in 2014 were analyzed by defined daily dose（DDD）and drug utilization index（DUI）. RESULTS：The diseases of opioids analgesics prescriptions for cancer pain in our hospital in 2014 were mainly lung cancer，accounting for 42.19％. Commonly used opioids analgesics included Morphine sulfate sustained-release tablets，Oxycodone Hydrochloride sustained-release tablets and so on，and their DUI were all below 1.0. Top one drug in the list of amount and consumption sum was Morphine sulfate sustained-release tablets，and its main dosage form were tablets，injection and patches，in which tablets occupied the largest proportion，reaching 97.30％. CONCLUSIONS：The application of opioids analgesics for cancer pain in our hospital is basically rational in terms of drug types，dosage form and route of administration，but the dose of opioids analgesics is small and their DUI is lower than 1；at the same time，there are a few irrational prescription.
