What analgesics are used for pain in late-stage cancer?

Cancer pain in the advanced stage is usually severe. Commonly used analgesics include nonsteroidal anti-inflammatory drugs (NSAIDs), weak opioids, and strong opioids. 1. Nonsteroidal anti-inflammatory drugs (NSAIDs): Such as acetaminophen and ibuprofen, are suitable for patients with mild pain and can effectively relieve pain caused by inflammation. 2. Weak opioids: Such as tramadol and codeine, are suitable for patients with moderate pain and can effectively control pain symptoms in most cancer patients. 3. Strong opioids: Such as oxycodone and morphine, are suitable for patients with severe pain and can significantly reduce the patient's pain. However, it should be noted that these drugs are addictive, and must be used strictly according to medical instructions. When using analgesics, patients should follow the doctor's guidance, selecting the appropriate medication according to the intensity and nature of the pain, and taking the medication on time, in order to maximize pain relief and reduce drug side effects.
