Mechanism of action

Both drugs work by activating mu opioid receptors throughout the brain and spinal cord, which decreases the transmission and perception of pain signals. They also produce sedation and euphoria by affecting reward pathways. Oxycodone is a semi-synthetic derivative with similar potency to morphine but different pharmacokinetics, while morphine is the natural alkaloid standard.
