Fatality due to amisulpride toxicity: a case report.
Amisulpride is an atypical antipsychotic agent effective in the treatment of schizophrenia. There are few cases in the literature relating to the toxicity of this agent and reported fatalities are rare. Drug induced prolongation of the QT interval of the electrocardiograph (ECG) is increasingly recognised with various classes of drugs and in particular with antipsychotics. Cardiotoxicity can manifest as ventricular tachyarrhythmia, including torsades de pointes (TdP), complicating QT prolongation. We report a case of fatal amisulpride toxicity where the post-mortem blood concentration was 48 mg/L. Hitherto under-recognised toxic effects of novel chemotherapeutic agents can pose challenges for the forensic pathologist charged with performing medico-legal autopsies in cases of sudden unexpected death in young adults and particularly in those with schizophrenia. A knowledge of the ability of antipsychotic agents to induce fatal cardiac arrhythmias should inform the approach to the autopsy (including determination of the cause and mechanism of death) in such cases, as should an appreciation of the dangers inherent in the interpretation of post-mortem toxicology.
