OxyContin is a brand name for the prescription medication known as oxycodone. It is a potent opioid analgesic primarily used for the management of moderate to severe pain when other pain medications are not sufficient.

OxyContin works by binding to opioid receptors in the brain and spinal cord, reducing the perception of pain. It is an extended-release formulation, designed to provide long-lasting pain relief over a 12-hour period.
