The effective diuretic dose of 5-HT3 receptor blocker RU-63 (1 mg/kg) was found in experiments on white rats. It is established that the diuretic and saluretic effects of compound RU-63 increase on the background of impact of the gravitational factor. Compound RU-63 (1 mg/kg, subcutaneously) administered daily under hypergravity conditions (3 g in the direction of centrifugal force toward the kidneys) in animals with model ischemic acute renal failure increased excretory function of kidneys, glomerular filtration rate, and creatininuresis (on average by 180%; p < 0.05), and decreased serum creatinine, urinary excretion of protein, lactate dehydrogenase, and g-glutamyl transferase (on average by 49%; p < 0.05) as compared to the untreated control. Under similar conditions, the diuretic hydrochlorothiazide (in a dose of 20 mg/kg, intragastric) produced a more pronounced creatininuretic action than that of RU-63 (by 358%; p < 0.05). |
