Indapamide, a newly developed antihypertensive agent with modest diuretic properties, reduced mean arterial pressure toward normal in dogs made hypertensive with salt and DOCA, while low-dose furosemide (0.1 mg per day) and hydrochlorothiazide (1 and 50 mg per day) did not result in similar degrees of blood pressure control. Indapamide, low-dose furosemide and hydrochlorothiazide treatment all resulted in similar decreases in body weight suggesting that the antihypertensive effect of indapamide occurs through a mechanism independent of contraction of extracellular fluid volume. Intravenous indapamide at doses of 0.3, 1.0 and 3.0 mg/kg caused progressive increases in sodium, potassium and chloride excretion when urine losses were replaced by isotonic saline to prevent extracellular fluid volume contraction. Only at 3.0 mg/kg did plasma potassium decrease significantly (2.92 +/- 0.03 to 2.69 +/- 0.05 mmol/l; p less than 0.05). Neither glomerular filtration rate (GFR) nor renal blood flow (flowmeter) decreased in a dose-related manner; however, effective renal plasma flow assessed by para-aminohippurate clearance did decrease about 15% at the highest dose (p less than 0.05). Proximal re-collection micropuncture studies demonstrated decreased proximal reabsorption. Cortical diluting segment reabsorption was decreased, but CNa + CH2O/GFR increased from 7% to 11% (p less than 0.05). These results indicate that, at doses up to 3.0 mg/kg, indapamide causes a natriuresis which is modest and similar to that seen with thiazides. No decrease in GFR or renal blood flow was observed. This drug apparently exerts a natriuretic effect through an inhibition of solute reabsorption in both the proximal nephron and the cortical diluting segment.
