Mechanism of action

Hydromorphone is a semi-synthetic opioid that activates mu-opioid receptors, inhibiting pain signal transmission and modulating pain perception. The OROS (osmotic release oral system) technology provides controlled, extended-release delivery over 24 hours, maintaining steady-state plasma concentrations and reducing dosing frequency compared to immediate-release formulations.
