Research of Tolvaptan prescription in SIADH patients (Observational research using DPC) - Research of Tolvaptan prescription in SIADH patients

As a result of examination using actual clinical data using the DPC database, half of the tolvaptan starting dose to SIADH was started from a low dose (3.75 mg), and the average administration period was 32.7 days for 3.75 mg and 33.1 days for 7.5 mg. Since mean of the serum sodium concentration at the start of the tolvaptan-administered case was 120.30 mEq / L, it is considered that the appropriate starting dose was selected for administration.
