Oxycodone is a semi-engineered narcotic alkaloid with pain-relieving effects that resembles morphine in chemical structure. The mu-receptors in the focused sensory system (CNS) are targeted by oxycodone, mimicking the effects of endogenous drugs.

Opioid drugs including OxyContin, Percocet, Percodan, and Roxicodone contain oxycodone, which is a strong opioid medication found in these well-known brand names: OxyContin, Percocet, Acetaminophen, and Aspirin.
