What medicine can I take to relieve the pain of rectal cancer?

There is no mention of what medicine to take for colorectal cancer. Non-opioid analgesics, weak opioid analgesics, strong opioid analgesics and other drugs can relieve pain for colorectal cancer.

First, non-opioid analgesics are used for patients with mild cancer pain. The main drugs include aspirin, acetaminophen, also known as paracetamol, etc.

Second, weak opioid analgesics are the main drugs for patients with moderate cancer pain or when non-opioid analgesics are not satisfactory for pain relief. They are generally used in combination with non-opioid analgesics. Due to the different mechanisms of the two drugs, non-opioid analgesics mainly act on the peripheral nervous system, while weak opioid analgesics mainly act on the central nervous system. Both can enhance the analgesic effect, and auxiliary drugs can also be used as needed.

Third, strong opioid analgesics are used to treat moderate and severe cancer pain. When non-opioid analgesics and weak opioid analgesics are ineffective, morphine is the main drug, and auxiliary drugs can also be used as appropriate. Currently, the commonly used strong opioid analgesics in clinical practice include sustained-release Oxcontin and Mescontin.
