Abstract

The dead body of a 54-year-old man was found at home by his partner. He was off work due to depression. A letter with suicidal intention was present on the scene. He was known to be a heavy drinker, and near the body, an empty bottle of whisky was found. In addition, 2 empty blisters of Eliquis (apixaban) 5 mg, corresponding to 40 tablets, were identified. Apixaban is an oral anticoagulant, acting as a factor Xa inhibitor. Autopsy findings were mostly unremarkable, except numerous bruises and some superficial self-inflected wounds. Histology showed hematomas of calyces and renal pelvis and in the liver, several areas of perivenular haemorrhagic necrosis. Others organs were congestive. Femoral venous blood alcohol was 0.11 g/L. In femoral venous blood, a toxic concentration of apixaban was measured at 1184 ng/mL using LC-MS/MS. Other drugs found at therapeutic concentrations included diazepam (99 ng/mL), nordiazepam (171 ng/mL), flecainide (447 ng/mL), and mianserine (65 ng/mL). Using liquid chromatography coupled to high-resolution mass spectrometry, 2 metabolites were identified, O-desmethyl-apixaban (61.8% of the apixaban response) and hydroxyl-apixaban (4.5% of the apixaban response). Long-term therapy was confirmed by a concentration of 10390 pg/mg in pubic hair.
