Overview

An opioid analgesic with actions and uses similar to those of morphine, apart from an absence of cough suppressant activity. It is used in the treatment of moderate to severe pain, including pain in obstetrics. It may also be used as an adjunct to anesthesia (From Martindale, The Extra Pharmacopoeia, 30th ed, p1092). On June 8, 2017, FDA requested Endo Pharmaceuticals to remove the medication from the market due to opioid misuse and abuse risks associated with the product's injectable reformulation.

Indication

For the treatment of moderate-to-severe pain.

Associated Conditions

  • Anxiety
  • Severe Pain
  • Moderate Pain

Research Report

A Comprehensive Pharmacological and Clinical Monograph on Oxymorphone (DB01192)

Executive Summary

Oxymorphone is a potent, semi-synthetic morphinane alkaloid and opioid analgesic first developed in Germany in 1914.[1] As a small molecule drug, it exerts its primary therapeutic and adverse effects through potent agonist activity at the µ-opioid receptor, making it an effective agent for the management of moderate-to-severe pain.[3] Clinically, it has been available in immediate-release (IR) formulations for acute pain and extended-release (ER) formulations for chronic pain requiring around-the-clock therapy.[5]

Its pharmacokinetic profile is distinguished by two key features: a very low oral bioavailability of approximately 10% due to extensive first-pass metabolism, and a metabolic pathway that proceeds primarily through glucuronidation, notably independent of the cytochrome P450 (CYP) enzyme system.[3] This latter characteristic theoretically positions it as a favorable option in patients on complex medication regimens to avoid CYP-mediated drug-drug interactions.
