Tricyclic antidepressant overdose

Tricyclic antidepressant overdose is an acute, potentially life-threatening toxic state resulting from the ingestion of supratherapeutic amounts of tricyclic antidepressant medications It primarily impairs the central nervous, cardiovascular, and autonomic systems in pediatric or adult populations Defining clinical features encompass rapid neurological deterioration with central nervous system depression or seizures, anticholinergic signs, and significant cardiotoxicity manifested by hypotension...

It primarily impairs the central nervous, cardiovascular, and autonomic systems in pediatric or adult populations

Pathophysiologically, toxicity stems from multi-receptor antagonism, including fast myocardial sodium channel blockade, central and peripheral muscarinic receptor antagonism, and peripheral alpha-1 adrenergic receptor inhibition Defining clinical features encompass rapid neurological deterioration with central nervous system depression or seizures, anticholinergic signs, and significant cardiotoxicity manifested by hypotension, QRS-interval prolongation, and severe ventricular dysrhythmias
