INFLUENCE OF THE N-ACETYLGLUCOSAMINE AND QUERCETIN COMBINATION IN THE INJECTABLE DOSAGE FORM ON THE COURSE OF ISCHEMIC ACUTE KIDNEY INJURY IN RATS
Introduction. Optimization of the treatment of acute kidney injury (AKI) is an important medical and pharmaceutical problem. AKI is a common complication not only of kidney diseases, but also of various treatment methods. Mortality caused by AKI reaches 80 % in some groups of patients. Therefore, the search for effective agents for AKI treatment is an important task of modern experimental pharmacology. A promising approach in the solution of this problem may be the implementation of pharmaceutical combination of flavonoid quercetin and amino sugar N-acetylglucosamine in injectable dosage form.
The aim of the study – experimental study of the efficacy of N-acetylglucosamine and quercetin combination in injectable dosage form under the condition of ischemic AKI.
Research Methods. Studies were performed on a model of ischemic AKI in rats, which was induced by total occlusion of the renal blood vessels for 75 minutes. The test combination was studied at a dose of 30 mg/kg with daily intravenous (i.v.) administration for 3 days in comparison with quercetin (“Corvitin” medication), which was injected i.v. at a dose of 34 mg/kg. The efficacy of test drugs was assessed by the animal functional state, excretory renal function and nitrogen metabolism indicators.
Results and Discussion. Under the influence of test combination, there was a significant decrease (p<0.05) in mortality rate in rats with AKI compared to untreated animals, a decrease in diuresis by 1.5 times and proteinuria by 2.4 times, an increase in glomerular filtration by 3.0 times and tubular reabsorption by 9.9 %, creatinine and urea excretion were increased by 1.4 and 1.9 times, respectively, which indicates the normalization of kidney functional state and nitrogen metabolism. Moreover, the combination was significantly (p<0.05) superior to the Corvitin effect in efficacy level by all studied parameters.
Conclusions. Thus, the N-acetylglucosamine and quercetin combination is an effective agent for AKI treatment, which can be used at i.v. administration. It is advisable to further study of this drug as a therapy for renal pathology.
