Summary
Nalbuphine is a strong analgesic with narcotic antagonist properties, offering pain relief comparable to morphine. It presents fewer disadvantages than other parenteral analgesics, with a low incidence of psychotomimetic reactions.
Area of Science:
- Pharmacology
- Toxicology
- Clinical Medicine
Background:
- Nalbuphine is a recently marketed parenteral strong analgesic.
- It possesses narcotic antagonist properties.
- Review of its properties is warranted.
Purpose of the Study:
- To review the chemical properties, pharmacology, and clinical efficacy of nalbuphine.
- To assess its adverse effects and compare it with other analgesics.
- To evaluate its safety profile.
Main Methods:
- Review of chemical properties.
- Analysis of animal and human pharmacology data.
- Evaluation of toxicity studies and clinical trial results.
Main Results:
- Nalbuphine demonstrates analgesic efficacy and potency similar to morphine.
- Adverse effects include sedation, nausea, and vomiting, with a low incidence of psychotomimetic reactions.
- It has minimal cardiovascular effects and may be advantageous in acute myocardial infarction patients by not causing hypotension.
Conclusions:
- Nalbuphine is an effective parenteral strong analgesic with a favorable safety profile.
- It appears to have fewer disadvantages compared to other available parenteral strong analgesics.
- Its abuse potential is likely similar to pentazocine.
