Oxycodone is a widely used prescription drug in the United States for the treatment of pain. It is an extended-release form of the opioid pain reliever, Buying Oxycodone, and is typically prescribed for moderate to severe pain. It is an opioid agonist, meaning that it binds to the same receptors in the brain as heroin and other strong opioid medications. Oxycodone is taken orally and is released slowly into the body to provide long-lasting pain relief.
