Tramadol is a prescription medication used for the management of moderate to moderately severe pain. It is classified as a centrally acting opioid analgesic and is available in both immediate-release and extended-release formulations.

Tramadol works by binding to opioid receptors in the brain and spinal cord, as well as inhibiting the reuptake of certain neurotransmitters, such as serotonin and norepinephrine. This dual mechanism of action helps to relieve pain and provide analgesia.
