Oxycodone vs. Endorphin: How Drugs Hijack Your Brain's Mu Opioid Receptors
Oxycodone, sold under brand names such as Percocet and OxyContin among many others, is an opioid medication which is used for the relief of moderate to severe pain. It is usually taken by mouth, and is available as a single-ingredient medication in immediate release and controlled release formulations. In the United Kingdom, it is available in 10 mg/mL and 50 mg/mL formulation for intramuscular or intravenous administration. Combination products are also available as immediate-release formulations, with non-narcotic analgesic ingredients such as paracetamol (acetaminophen) and nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin and ibuprofen.
