A prescription drug called tramadol is used to relieve moderate to severe pain. It is a member of the opioid analgesics pharmacological class. In order to change how the body perceives and reacts to pain, tramadol binds to opioid receptors in the brain and spinal cord. Its ability to impede the reuptake of norepinephrine and serotonin may potentially play a role in its analgesic properties. There are several different ways to get Tramadol, including as tablets with immediate release, pills with delayed release, and capsules. The degree of pain and the patient's reaction to the drug determine how much and how often tramadol should be used.
