Diuretic activity of 4-O-Carboxyphenyl-D-Glucopyranoside sodium salt administered via different routes

It was compared the diuretic activity of the sodium salt of 4-(0-β-D-glucopyranosyloxy)benzoic acid for enteral (intragastric) and parenteral ways of administration. The test substance was administered enterally and parenterally (subcutaneously in the region of the withers) in a daily dose of 18 nmol/kg for the first seven days and in a dose of 54 mmol/kg for the next seven days. Diuretic activity of the sodium salt of 4-(0-β-D-glucopyranosyloxy)benzoic acid was evaluated in terms of urine volume. Urine was analyzed for creatinine and the concentration of sodium, potassium and chloride ions. Experiments showed that the sodium salt of 4-(0-β-D-glucopyranosyloxy)benzoic acid produced a diuretic effect only for the enteral administration route.
