A highly sensitive and specific high-performance liquid chromatographic assay was applied, clearly identifying all three compounds in plasma extracts as separate peaks. In four subjects peak plasma concentrations of proguanil (500 to 600 nmol/l) were reached after two to three hours, while cycloguanil and p-chlorophenylbiguanide showed a plateau after three and six hours, respectively. In the fifth subject peak concentrations of proguanil and cycloguanil appeared after seven hours. Trough concentrations (pre-dose in the morning) of proguanil and cycloguanil were about 200 and 100 nmol/l, respectively. Mean half-life of proguanil was estimated to approximately 20 h. The active metabolite cycloguanil constituted 30% of the total plasma drug concentration. The concentration of proguanil was higher in erythrocytes than in plasma, while that of cycloguanil was lower. Relevant clinical studies correlating plasma concentrations to the suppressive activity against malaria will be possible to perform based on the applied method and presented kinetic data.",
