Аннотация
A case of fatal intoxication from metformin is presented. The decedent was an obese 58-year-old-woman with type II diabetes, in whom severe lactic acidosis secondary to metformin accumulation was precipitated by acute renal failure. She had been on metformin 500 mg twice a day. Postmortem blood was deproteinated with acetonitrile, washed with dichloromethane, and the resulting supernatant injected into high-performance liquid chromatography system. Separation was performed on a analytical 125 x 4 mm i.d. RP-8 column. The wavelength was set at 235 nm. The mobile phase was acetonitrile (40%), sodium lauryl sulfate, and sodium dihydrogen phosphate adjusted to pH 5.1 (60%) at a flow rate of 1.0 mL/min. The concentration of metformin in postmortem blood was 77.3 microg/mL. The qualitative result was also confirmed by LC/APCI/MS/MS analysis.
