Comparison of metabolic abnormalities 48 weeks after switching from highly active antiretroviral therapy containing a non-nucleoside reverse transcriptase inhibitor to Trizivir versus continued highly active antiretroviral therapy

AIDS. 2003 Aug 15;17(12):1855-6. doi: 10.1097/00002030-200308150-00017.


Forty patients participating in the TRIZAL study were treated with a non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing regimen before being randomly assigned either to continue their baseline therapy or to switch to a triple nucleoside regimen. No difference was observed in treatment efficacy between the two groups, and total cholesterol was observed to improve significantly in the switch group. Switch maintenance may be an appropriate strategy in patients treated with an NNRTI.
