Area of Science:

  • Analytical Chemistry
  • Toxicology
  • Pharmacology

Background:

  • Chloroquine is an antimalarial drug with a narrow therapeutic index.
  • Overdose can lead to severe toxicity and death.
  • Accurate quantification in biological matrices is crucial for clinical and forensic toxicology.

Observation:

  • High-performance liquid chromatography (HPLC) was utilized for precise measurement.
  • Biological fluids and tissues were analyzed post-mortem.
  • A significant blood chloroquine concentration was determined.

Findings:

  • The blood chloroquine concentration was quantified at 16.71 mg/l.
  • This concentration is significantly higher than therapeutic levels.
  • The findings align with a fatal chloroquine overdose scenario.

Implications:

  • Establishes a critical blood concentration threshold for chloroquine toxicity.
  • Highlights the importance of HPLC in forensic analysis of drug overdose cases.
  • Provides data for clinical management and understanding of chloroquine poisoning outcomes.
