ABSTRACT
<p><b>BACKGROUND</b>The pharmacokinetics of zidovudine (AZT) are possibly influenced by weight, age, sex, liver and renal functions, severity of disease, and ethnicity. Currently, little information is available on the steady-state pharmacokinetics of AZT in Chinese HIV-infected patients. The current study aimed to characterize the steady-state pharmacokinetics of AZT in a Chinese set-up.</p><p><b>METHODS</b>Eleven Chinese HIV-infected patients were involved in the steady-state pharmacokinetic study. In total, 300 mg of AZT, as a part of combination therapy, was given to patients, and serial blood samples were collected for 12 hours. The samples were measured by a high-performance liquid chromatography (HPLC) assay, and the results were analyzed by both the non-compartment model and the one-compartment model.</p><p><b>RESULTS</b>The C(max) of AZT in Chinese patients was higher than that in non-Asian patients. The half-life of AZT, analyzed by the non-compartment model (P = 0.02), in male patients ((1.02 ± 0.22) hours) was shorter than that of AZT in female patients ((1.55 ± 0.29) hours). The AZT clearance, analyzed by the one-compartment model (P = 0.045), in male patients ((262.60 ± 28.13) L/h) was higher than that in female patients ((195.85 ± 60.51) L/h).</p><p><b>CONCLUSION</b>The present study provides valuable information for the clinical practice of AZT-based highly active antiretroviral therapy in a Chinese set-up.</p>
