Objective To assess the efficacy and safety Losartan for essential hypertension associated with
hyperuricemia.
Methods Included randomized controlled trials of Losartan versus Valsartan. Electronic search
conducted in CENTRAL, the Cochrane Library (until 2008, Issue 4), PubMed, EMBASE, Chinese Biomedicine database,
Chinese Scientific Journals Full-text Database, and China Journal Full-text Database (until 2008, Issue 10). Two reviewers extracted data independently. RevMan 5.0 software developed by the Cochrane Collaboration was used for Metaanalysis.
Results Only 7 trials with 1 136 eligible patients were included in the systematic review. Meta-analysis showed
no significant difference in reductions of systolic blood pressure, diastolic blood pressure, and adverse events between
Losartan and Valsartan groups. However, a significant difference of serum uric acid reduction was observed between
Losartan and Valsartan group. Losartan play a significant role of decreased serum uric acid levels.
Conclusions Based on this systematic review, Losartan is effective and well tolerated in reducing BP and serum uric acid levels. Further large randomized, double blind, placebo controlled trials are needed in long-term safety and efficacy and different subgroups of Losartan.
