概览

Oxycodone is an opioid used in the management of moderate to severe pain.

作用机制

The full mechanism of oxycodone is not known. Under conditions of inflammation or hyperalgesia, opioid receptors in the heart, lungs, liver, gastrointestinal tract, and reproductive system are upregulated and transported to nerve terminals. Oxycodone and its active metabolites, noroxycodone, oxymorphone, and noroxymorphone are opioid agonists. These compounds passively diffuse across the blood brain barrier or may be actively transported across by an unknown mechanism. Oxycodone and its active metabolites can selectively bind to the mu opioid receptor, but also the kappa and delta opioid receptors in the central nervous system and periphery, and induce a G protein coupled receptor signalling pathway. Activation of mu opioid receptors inhibits N-type voltage operated calcium channels, inhibiting responses to pain.

适应症
