[Three cases of acute methamphetamine intoxication--analysis of optically active methamphetamine]
1Department of Legal Medicine School of Medicine, Teikyo University.
Abstract:
Three typical cases of acute methamphetamine intoxication are reported. The concentrations of methamphetamine in the blood were 27.2, 6.43 and 0.60 micrograms/ml, respectively. All three victims had been exposed to high temperature in a bathroom or a closed room in summer at the time of death. Macroscopic autopsy revealed hemorrhagic pulmonary edema, and histologically, diffuse contraction-band necrosis was evident in the myocardium in all cases. The absolute structures of six illegally available methamphetamine showed an (S)-configuration with an optical purity of > 99% in enantiomeric excess and four were racemic form.
Insights
Acute methamphetamine intoxication can be fatal, especially in hot environments. Autopsies revealed pulmonary edema and myocardial damage in victims with high blood methamphetamine levels. Illicit methamphetamine samples were predominantly of high optical purity.
Area of Science:
- Forensic Toxicology
- Cardiovascular Pathology
- Organic Chemistry
Background:
- Acute methamphetamine intoxication presents a significant public health concern.
- Understanding the toxicological profile and pathological effects is crucial for forensic investigations.
- Illicit drug analysis aids in identifying drug sources and purity.
Observation:
- Three cases of fatal acute methamphetamine intoxication are presented.
- Victims were exposed to high ambient temperatures during intoxication.
- Blood methamphetamine concentrations ranged from 0.60 to 27.2 µg/ml.
Findings:
- Autopsies revealed hemorrhagic pulmonary edema in all cases.
- Histological examination showed diffuse contraction-band necrosis of the myocardium.
- Analysis of illicit methamphetamine samples indicated high enantiomeric purity ((S)-configuration) in some and racemic mixtures in others.
Implications:
- Methamphetamine intoxication, particularly in hot conditions, can lead to severe cardiovascular and pulmonary complications.
- High purity and specific enantiomeric forms of methamphetamine may influence toxicity.
- These findings underscore the importance of forensic analysis in determining drug-related fatalities.
