Fatal benztropine toxicity.

Abstract

Benztropine is an anticholinergic agent used in the treatment of Parkinson's disease and drug induced extrapyramidal disorders. We report a case of fatal benztropine toxicity. This drug is regarded as relatively safe and reports of isolated toxicity are scarce. In ascribing a particular death to fatal drug toxicity the forensic pathologist must take into account the circumstances surrounding the death, the presence and significance of any co-existent natural disease and the potential contribution of any other detected therapeutic or illicit agents. This interpretation will occur in the knowledge that certain drugs will not be detected and that with respect to quantification of postmortem drug levels, the notion of postmortem redistribution should always be considered.
