Hyperosmotic solution of isosorbide has been used for treatment of Menieres disease since Kitahara et al., Larsen et al. and Nozawa et al.. In recent studies reported that ADH is acting to open water channels, AQP-2 at the endlymphatic membrane and may act worse for labyrinthine hydrops. It is important the serum concentration of isosorbide after administration because ADH should be released if the serum osmotic pressure is elevated by isosorbide above more than 2% of normal serum osmotic pressure. In this study the equation predicting isosrbide serum concentration after oral administration was proposed on the basis of the data by Wakiyas report. It was confirmed the serum osmotic pressure remains below the threshold level for increasing ADH secretion by the routine method of 30 ml/once, 3 times every day. However, the method of 30 ml/once, single or two times every day should be recommended when the serum osmotic pressure before the medication is above 289 mOsm/kg.
