Tramadol modifies the body's perception and reaction to pain by attaching itself to opioid receptors in the brain and spinal cord. Its potential to act as a serotonin and norepinephrine reuptake inhibitor may possibly play a role in its analgesic properties. There are several different types of Tramadol that are available, such as capsules, extended-release tablets, and tablets with quick release. The degree of pain and each person's reaction to the drug determine how much and how often tramadol should be administered.
