Summary
Pentazocine overdose can cause severe symptoms like seizures and coma. This case suggests higher naloxone doses (5-20 mg) may be needed for effective treatment of pentazocine overdose.
Area of Science:
- Toxicology
- Emergency Medicine
- Pharmacology
Background:
- Pentazocine is an opioid analgesic with potential for overdose.
- Opioid overdose typically involves respiratory depression and altered mental status.
Observation:
- A patient presented with status epilepticus, coma, respiratory depression, acidosis, hypotension, and ventricular arrhythmias after ingesting 1.5 g of pentazocine.
- The patient survived with supportive care but did not respond to standard naloxone doses.
Findings:
- Pentazocine overdose can lead to a complex clinical presentation including neurological and cardiovascular emergencies.
- Conventional naloxone dosages were insufficient in this case, indicating a potential need for higher administration.
Implications:
- This case highlights the critical need for aggressive supportive measures in severe pentazocine overdose.
- Higher doses of naloxone (5-20 mg) should be considered for managing pentazocine overdose when initial response is inadequate.
