Description
Oxycodone, sold under various brand names such as Roxicodone and OxyContin (which is the extended release form), is a semi-synthetic opioid used medically for treatment of moderate to severe pain. It is highly addictive[14] and is a commonly abused drug.[15][16] It is usually taken by mouth, and is available in immediate-release and controlled-release formulations.[15] Onset of pain relief typically begins within fifteen minutes and lasts for up to six hours with the immediate-release formulation.[15] In the United Kingdom, it is available by injection.[17] Combination products are also available with paracetamol (acetaminophen), ibuprofen, naloxone, naltrexone, and aspirin.[15]
Common side effects include euphoria, constipation, nausea, vomiting, loss of appetite, drowsiness, dizziness, itching, dry mouth, and sweating.[15] Side effects may also include addiction and dependence, substance abuse, irritability, depression or mania, delirium, hallucinations, hypoventilation, gastroparesis, bradycardia, and hypotension.[15] Those allergic to codeine may also be allergic to oxycodone.[15] Use of oxycodone in early pregnancy appears relatively safe.[15] Opioid withdrawal may occur if rapidly stopped from withdrawal.[15] Oxycodone acts by activating the μ-opioid receptor.[18] When taken by mouth, it has roughly 1.5 times the effect of the equivalent amount of morphine.
