Tramadol, also known by its brand name Ultram, is a prescription medication used to treat moderate to severe pain. It belongs to a class of drugs called opioid analgesics, which work by binding to opioid receptors in the brain and spinal cord. This leads to a decrease in the transmission of pain signals and an increase in the production of dopamine, a neurotransmitter that can produce feelings of pleasure and well-being. Tramadol is often prescribed for conditions such as back pain, fibromyalgia, and post-surgical pain. It is also commonly used to manage pain in cancer patients. Tramadol comes in a variety of forms, including immediate-release tablets, extended-release tablets, and oral disintegrating tablets. The dosage and frequency of use are determined by a doctor based on the severity of the pain and the patient's medical history. While tramadol can be an effective pain reliever, it also carries potential risks and side effects.
