title: Serial serum drug concentrations and prolonged anticholinergic toxicity after benztropine (Cogentin) overdose.
abstract: A 38-year-old man overdosed on benztropine mesylate (Cogentin; Merck Sharpe & Dohme, West Point, PA) and developed anticholinergic poisoning syndrome, which lasted nine days. Serial serum benztropine concentrations were obtained during his hospitalization. Fluctuating benztropine levels suggested that his lengthy intoxication may have been secondary to prolonged, intermittent absorption rather than from slow plasma clearance. This is believed to be the first report of serial serum benztropine concentrations after overdose.
