EDO SOLSONA, M.ª D. et al. Effectiveness and adequacy of tolvaptan prescription in hospitalized patients. Farm Hosp. [online]. 2013, vol.37, n.3, pp.178-181. ISSN 2171-8695.  https://dx.doi.org/10.7399/FH.2013.37.3.537.

Purpose: To analyse the effectiveness of the use of Tolvaptan and the adequacy of Tolvaptan prescription at a tertiary level hospital. Methods: Prospective observational study of Tolvaptan prescription from October of 2010 to December of 2011. Results: 30 patients (60.0% males) were included, 50.0% of which were diagnosed with heart failure and 30.0% with SIADH. Tolvaptan allowed achieving sodium levels higher than 135 mEq/L in 53.3% of the patients with a mean baseline value of 125.3±7.3 mEq/L. The median treatment duration was 5.0 days (interquartile range = 3-45). A significant increase of uric acid associated to Tolvaptan treatment was observed. The prescription was in agreement to what has been established in GFT in 63.3% of the cases. Conclusions: Tolvaptan increases sodium levels by 7.5 mEq/L, both in SIADH-associated hyponatremia and in heart failure, with an appropriate safety profile.
