Oxycodone

Oxycodone, sold under the brand names Roxicodone and OxyContin (which is the extended-release form) among others, is a semi-synthetic opioid used medically for the treatment of moderate to severe pain. It is a highly addictive and commonly abused drug. It is usually taken orally, and is available in immediate-release and controlled-release formulations. Onset of pain relief typically begins within fifteen minutes and lasts for up to six hours with the immediate-release formulation. In the United Kingdom, it is available by injection. Combination products are also available with paracetamol (acetaminophen), ibuprofen, naloxone, naltrexone, and aspirin. Common side effects include euphoria, constipation, nausea, vomiting, loss of appetite, drowsiness, dizziness, itching, dry mouth, and sweating. Side effects may also include addiction and dependence, substance abuse, irritability, depression or mania, delirium, hallucinations, hypoventilation, gastroparesis, bradycardia, and hypotension. Those allergic to codeine may also be allergic to oxycodone. Opioid withdrawal may occur if rapidly stopped. Oxycodone acts by activating the μ-opioid receptor. When taken by mouth, it has roughly 1.5 times the effect of the equivalent amount of morphine. Oxycodone was originally produced from the opium poppy opiate alkaloid thebaine in 1916 in Germany. One year later, it was used medically for the first time in Germany. Oxycodone is available as a generic medication. In 2023, it was the 49th most commonly prescribed medication in the United States, with more than 13 million prescriptions....
