Summary
Oxycodone offers superior oral absorption compared to morphine but shares similar abuse potential. Its metabolism via CYP2D6 is hindered by liver issues, and its high cost limits hospice use.
Area of Science:
- Pharmacology
- Pain Management
- Toxicology
Background:
- Oxycodone is a widely used opioid analgesic in the United States.
- It exhibits enhanced oral absorption and bioavailability compared to morphine.
- Oxycodone's pharmacokinetic profile is influenced by gender and hepatic function, specifically via CYP2D6 metabolism.
Purpose of the Study:
- To review the pharmacological properties of oxycodone.
- To compare oxycodone with morphine regarding absorption, metabolism, and clinical use.
- To discuss the safety profile, abuse potential, and cost-effectiveness of controlled-release oxycodone.
Main Methods:
- Literature review of oxycodone's pharmacological characteristics.
- Comparative analysis of oxycodone and morphine properties.
- Examination of clinical data on oxycodone's efficacy, safety, and abuse potential.
Main Results:
- Oxycodone demonstrates superior oral absorption and bioavailability over morphine.
- CYP2D6-mediated metabolism of oxycodone is significantly impacted by liver dysfunction.
- Controlled-release oxycodone shares analgesic effects, side effects, and abuse potential with controlled-release morphine; deaths often involve polysubstance abuse.
Conclusions:
- Oxycodone is a potent opioid with distinct pharmacokinetic advantages but risks similar to other opioids.
- Liver dysfunction poses a significant challenge for oxycodone metabolism.
- The high cost of controlled-release oxycodone restricts its accessibility in hospice care.
