摘要

Diethylcarbamazine (DEC) is a drug of choice to treat lymphatic filariasis (LF) either used alone or in combination as mass drug administration (MDA) preventive strategies. The objective of this study was to develop a population pharmacokinetics (PK) model for DEC in subjects infected with lymphatic filariasis (LF) compared to healthy individuals, and to evaluate the effect of covariates on the volume of distribution (V/F) and oral clearance (CL/F) of DEC. This was an open-label cohort study of treatment-naive Wuchereria bancrofti-infected (n = 32) and uninfected (n = 24) adults residing in the Agboville District of Cote d'Ivoire. The population pharmacokinetics model for DEC was built using Phoenix NLME 8.0 software. The covariates included in the model-building process were age, gender, body weight, infection status, creatinine clearance (CLCR), and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. A total of 56 adults were enrolled in the study, and a total of 728 samples were obtained over 168 h. A one-compartment linear pharmacokinetics model with first-order absorption with an absorption lag time (T-lag) best described the data. After determining the pharmacokinetics (PK) parameters of DEC, body weight and gender were found to be the significant covariates for DEC V/F. The final population pharmacokinetics model adequately described the pharmacokinetics of DEC in the studied population. Model-based simulation indicated that the body weight significantly impacted the exposure in both the male and female populations. This analysis may further support the drug-drug interaction model development of DEC with different coadministered drugs or agents in disease control programs.
