Procainamide depleted tablets not a cause of death

Area of Science:

• Forensic Toxicology
• Pharmacology

Background:

• Investigating the fate of orally administered drugs in post-mortem cases.
• Understanding drug distribution and metabolism in the gastrointestinal tract.

Observation:

• Sixteen intact procainamide tablets were discovered throughout the gastrointestinal tract of a man who died from arteriosclerotic heart disease.
• Tablets showed varied stages of drug depletion.

Findings:

• Procainamide was identified in the tablets using thin layer chromatography, ultraviolet spectrophotometry, and gas chromatography/mass spectrometry.
• Liver procainamide concentration was within the therapeutic range.
• The presence of procainamide was not considered a contributing factor to the patient's death.

Implications:

• Highlights the importance of post-mortem drug analysis for accurate cause of death determination.
• Demonstrates the utility of advanced analytical techniques in forensic investigations.
• Provides insight into drug persistence and distribution within the digestive system after death.
