Dapsone and Body Mass Index in Subjects With Multibacillary Leprosy.
Abstract
BACKGROUND:: The physiological changes in obese subjects can modify the pharmacokinetic profiles of drugs influencing the therapeutic efficacy.
METHODS:: In this study, the authors compare plasma dapsone trough levels of multibacillary leprosy subjects stratified by body mass index (BMI) to evaluate if obesity plays a significant role on drug levels. The relationship between drug levels and BMI was also determined. Dapsone was measured by high-performance liquid chromatography and BMI based on World Health Organization criteria.
RESULTS:: At steady state, the median plasma dapsone trough level was significantly lower in obesity class 2 group, when compared with other groups, but they were similar between normal weight and preobesity groups. A weak association between drug levels and BMI was observed.
CONCLUSIONS:: Obesity promotes a significant reduction in plasma dapsone trough levels of subjects with multibacillary leprosy with a weak association between drug levels and BMI.
