Design outcomes

Primary

MeasureTime frame
1. viral load as a measure of regimen efficacy. This will be determined by qRT-PCR 2. Incidences and severity of neuropsychiatric adverse drug reactions this will be determined by neuropsychiatric adverse effects evaluation tools

Secondary

MeasureTime frame
Efavirenz plasma concentrations and correlations with CYP2B6 genotype and relation to neuropsychiatric side effects. The EFV concentrations will be determined by LC-MSMS and the CYP2B6 genotype by the QRTPCR method, which will have been validated in this study.
