The purpose of this study is to compare 2 different doses of ATV.
We are interested in once daily ATV/r 200/100 mg OD because ATV dose reduction may reduce toxicity and cost compared to standard dose ATV/r at 300/100mg OD. There are limited prospective randomized studies evaluating the long term efficacy and safety of lower dose ATV/r OD dose in combination of NRTIs in HIV-1 pretreated patients. We believe that the efficacy of ATV/r given at 200/100mg daily in Thai patients will be equivalent to ATV/r 300/100mg once daily when combined with 2NRTIs, and that the low dose ATV/r will have better safety, tolerability profile, and cost saving while maintaining good CD4 and HIV RNA outcomes.
