[Clinical trial of indapamide in the management of central diabetes insipidus].

To investigate antidiuretic effect of indapamide, ten patients with central diabetes insipidus (CDI) were observed with the treatment of 2.5-7.5 mg of indapamide per day. After the third day of therapy, their mean daily urine output reduced by about 50%, and urine osmolality increased 1.36 times. No further change was seen in urine volume and urine osmolality on the sixth day of treatment. This antidiuretic effect was similar to that of 50-75 mg dihydrochlorothiazide per day. No adverse reaction was observed in blood pressure and serum potassium concentration during indapamide therapy. These data suggest that indapamide may be a new drug in the management of CDI.
