Abstract:
Severe amitriptyline toxicity may cause coma, hypotension, convulsions, supraventricular and ventricular arrhythmias, metabolic/respiratory acidosis and cardiac arrest. Management with gastric lavage, activated charcoal, alkalinization with sodium bicarbonate and supportive care with mechanical ventilation, antiarrhythmics and anticonvulsants if required, is the common approach. Herein, we report successful treatment of severe amitriptyline poisoning in three cases by plasma exchange in addition to the above supportive measures. Plasma exchange may have a beneficial role in lethal doses of amitriptyline ingestion because of the high plasma protein binding property of amitriptyline.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
