Measurements of 5,6-Orthoquinone, a Surrogate for the Presumed Active Primaquine Metabolite 5-Hydroxyprimaquine, in the Urine of Cambodian Adults

Abstract

The active metabolites of primaquine, in particular 5-hydroxyprimaquine, likely responsible for the clearance of dormant hypnozoites, are produced through the hepatic CYP450 2D6 (CYP2D6) enzymatic pathway. With the inherent instability of 5-hydroxyprimaquine, a stable surrogate, 5,6-orthoquinone, can now be detected and measured in the urine as part of primaquine pharmacokinetic studies.
