Mechanism of action

Oxycodone is a semi-synthetic opioid agonist that binds primarily to mu (μ) opioid receptors in the brain and spinal cord, inhibiting pain signal transmission and producing analgesic effects. The extended-release (ER) formulation uses a proprietary technology to provide sustained drug delivery over 12 hours, reducing dosing frequency while maintaining consistent pain control. Xtampza ER's formulation is designed to be abuse-resistant, making it difficult to crush, chew, or dissolve for misuse.
