Tricyclic Anti-Depressants

Tricyclic antidepressants are commonly used for the treatment of depressive disorders. TCA overdoses can result in profound central nervous system depression, cardiotoxicity and anticholinergic effects. TCA overdose is the most common cause of death from prescription drugs. TCA's are taken orally or sometimes by injection. TCA's are metabolized in the liver. Both TCA's and their metabolites are excreted in urine mostly in the form of metabolites for up to ten days.
