OxyContin is a brand name for the medication known generically as oxycodone. It is a prescription opioid analgesic primarily used for the management of moderate to severe pain when around-the-clock pain relief is needed.

Oxycodone, the active ingredient in OxyContin, works by binding to opioid receptors in the brain and spinal cord, thereby reducing the perception of pain. OxyContin is formulated as an extended-release tablet, providing a controlled release of the medication over an extended period of time.
