Amitriptyline and tianeptine poisoning treated by naloxone.
BACKGROUND
Severe amitriptyline toxicity may cause cardiac dysrhythmias, severe hypotension, convulsions and CNS depression, including coma. Management with gastric lavage, activated charcoal, alkalinization and supportive care with mechanical ventilation, antiarrhythmics and anticonvulsants, if required, is the general approach.


METHODS
A 33-year-old woman who had taken overdose antidepressants (amitriptyline and tianeptine) was admitted to the emergency service. She was intubated because she had pure respiratory arrest. Besides hypotension (80/60 mmHg), she was unresponsive to verbal and painful stimuli and her Glasgow coma score was 6. Hemogram and serum biochemical parameters and electrocardiography were within normal limits. The patient was examined for substance dependence and no trace of the injector was found in the body. Patient underwent a coma cocktail (naloxone 2 mg/body, 50% dextrose 25g/body and thiamin 100 mg/body). [corrected] Activated charcoal and intravenous alkalinization by NaHCO(3) were initiated. Spontaneous respiration started again 20 min after being given the coma cocktail. She became responsive to verbal stimuli first hour after the coma cocktail, and her Glasgow coma score improved to 13. She had spent 2 days in the service and was discharged by the second day of admission, without any complications.


CONCLUSIONS
Herein, we report successful treatment in a case of severe amitriptyline and tianeptine poisoning by naloxone in addition to the above supportive care. Naloxone treatment may have a beneficial role in lethal doses of amitriptyline ingestion because amitriptyline may affect opioid receptors.
