Sudden death of a volunteer

Lancet. 1985 Jan 12;1(8420):93-4. doi: 10.1016/s0140-6736(85)91977-4.


A volunteer participating in a study of eproxindine, a new antiarrhythmic agent, had a sudden cardiorespiratory arrest and died. Subsequently it became known that he had received a depot injection of flupenthixol on the day before his death; an interaction between these two drugs seems likely. This incident illustrates that it is impossible to guarantee absolute safety in volunteer studies if details of medical history are withheld.
