Pentazocine Injection
What is Pentazocine Injection?
Pentazocine Injection is a synthetic opioid analgesic used for the relief of moderate to severe pain. It belongs to the benzomorphan class of opioids and acts as a mixed agonist–antagonist at opioid receptors. It is widely used in post-operative care, trauma management, and obstetric analgesia, making it an essential medicine in hospitals and emergency care units.
Uses of Pentazocine Injection
- Relief of moderate to severe pain
- Pre-operative medication to reduce anxiety and pain
- Post-operative pain management
- Obstetric analgesia during labor (with caution)
- Short-term use in patients intolerant to morphine or other opioids
How Does Pentazocine Injection Work?
Pentazocine works by binding to kappa-opioid receptors (agonist action) and partially blocking mu-opioid receptors (antagonist effect). This dual activity provides effective pain relief while reducing the risk of respiratory depression and euphoria compared to full opioid agonists, thereby lowering its abuse potential.
