Tramadol works by binding to opioid receptors in the brain, which helps to reduce the perception of pain. It also inhibits the reuptake of certain neurotransmitters, such as serotonin and norepinephrine, which can contribute to its analgesic effects. This medication is often prescribed for various conditions, including post-operative pain, chronic pain, and pain associated with conditions like arthritis or fibromyalgia. Tramadol is available in different formulations, including immediate-release tablets, extended-release tablets, and oral capsules.
