Tramadol hydrochloride (Ultram®) is a prescription medication licensed for the treatment of pain. Specifically, tramadol benefits include treating moderate to moderately severe pain in adults (age 16 and older).
Tramadol is classified as a "centrally acting opioid analgesic." This means that it works in the central nervous system (the brain and spinal cord), acts much like morphine in the body, and relieves pain. Tramadol also works in a similar manner as some antidepressant medications by inhibiting the reuptake of certain brain chemicals (serotonin and norepinephrine).
Originally, tramadol was marketed as a medication with weak narcotic effects and little potential for abuse. However, research has since demonstrated that this drug works primarily through morphine-like activity, and numerous cases of abuse and dependence have been reported.
