OxyContin is a brand name for the medication oxycodone. It is a powerful opioid analgesic used for the management of moderate to severe pain. OxyContin contains extended-release oxycodone, which provides long-lasting pain relief over an extended period.

Oxycodone, the active ingredient in OxyContin, works by binding to opioid receptors in the brain and spinal cord, reducing the perception of pain. It is commonly prescribed for chronic pain conditions, such as cancer-related pain or severe pain that is not adequately managed by other pain medications.
