Tramadol is a medication used to relieve moderate to moderately severe pain. It belongs to a class of drugs called opioid analgesics, and it works by binding to opioid receptors in the brain, altering the way the body perceives and responds to pain. Tramadol is primarily prescribed for the treatment of acute and chronic pain conditions, such as post-surgical pain, musculoskeletal pain, neuropathic pain, and pain associated with conditions like osteoarthritis and fibromyalgia.
