AIMS: Several studies reported treatment benefits of tolvaptan in patients with
congestive heart failure (CHF). However, the optimal dosage remains unclear. We
aimed to compare different dosage of tolvaptan to determine the optimal dosage in
terms of the efficacy and safety. METHODS: We searched MEDLINE, PubMed, EMBASE,
Cochrane CENTRAL and ClinicalTrials.gov through Aug 31, 2016. Randomized
controlled trials (RCTs) comparing tolvaptan of different dosages or to placebo
in patients with CHF were included. We used network meta-analysis to look for the
optimal dosage in terms of effectiveness and safety. Urine output, body weight
change and change in serum sodium were the main outcomes of efficacy. Adverse
effects were the secondary outcomes. Quality was assessed by Cochrane
risk-of-bias tool. RESULTS: Twelve RCTs reporting 14 articles with 5793 patients
(mean age, 65.7 ± 11.9 years; 73.7% man) were included. Compared with placebo,
the tolvaptan 30 mg had similar effects to tolvaptan 45-90 mg in terms of urine
output (mean difference [MD] 2.03 liter; 95% confidence interval [CI] 1.3 to
2.71), body weight change (MD -1.12 kg; 95% CI -1.37 to -0.88) and change in
serum sodium (MD 3.06 meq/L; 95% CI 2.43 to 3.68). Compared with placebo,
tolvaptan of different dosage showed a non-significant higher risk of adverse
effects. CONCLUSIONS: These findings suggest that tolvaptan 30 mg and 45 mg may
be the optimum dosage for CHF patients, because of its ability to provide
favourable clinical results without greater adverse effects. However, tolvaptan
is not beneficial for reducing all-cause mortality in CHF patients.
