[Tissue distribution of chloroquine in 18 cases of voluntary poisoning]

Chloroquine has been studied in some tissues of 18 subjects dead after fatal absorption of this drug. The assays have been made by U. V. Spectrophotometry, a simple, rapid and specific method. The found concentrations are highly heterogenous according to individuals and organs; generally, the higher levels are found in the liver, the spleen and the kidneys and the lower levels in the brain.
