An unusual death by propranolol ingestion.

A case of acute intoxication with propranolol is reported. A 60-year-old man was found dead in his car with no evidence of trauma or signs of asphyxia. Near the car, a pharmaceutical box of Inderal, a pharmaceutical formulation containing propranolol, was found. The man was not under therapy with this medication, but circumstantial data suggested the use of this medicine by his sister. High blood levels of propranolol confirmed the suspected drug use and induced us to discuss the probable lethal mechanism of this substance. The analysis of this compound was performed by liquid-liquid extraction followed by gas chromatography/mass spectrometry determination.
