Oxycontin is a prescription-only extended-release opioid analgesic used for the management of moderate to severe pain, particularly when long-acting pain relief is required. It contains oxycodone, which binds to opioid receptors in the brain and spinal cord to reduce the perception of pain. Because of its high potential for misuse, dependence, and serious side effects, Oxycontin is strictly regulated and must only be used under the supervision of a licensed healthcare professional.
