The study of the efficacy of combined medicines of quercetin and glucosamine derivatives in rats with the end-stage renal failure




quercetin, N-acetylglucosamine, glucosamine hydrochloride, end-stage renal failure, adenine-induced nephropathy


Chronic kidney disease (CKD) is the most significant pathology among diseases of the urinary system, which leads to the inevitable development of renal failure. Currently, there are no effective treatments for the end-stage form of CKD in clinical practice.
Aim. To study of the effect of combined medicines of quercetin with glucosamine derivatives in the experiment using various routes of administration on the course of the end-stage renal failure.
Materials and methods. The study was performed on the model of adenine-induced nephropathy in rats. Test samples were administered intragastrically (80 mg/kg) and intramuscularly (30 mg/kg) for 4 weeks starting in 4 weeks after beginning of the experiment. Corvitin was used as a reference drug in the dose of 34 mg/kg. The efficacy of test drugs was assessed by indicators of the kidney functional state and nitrogen metabolism.
Results. In 8 weeks after the pathology simulation under the influence of both test objects a positive effect on the course of renal failure was observed. In this case, an injection combination of quercetin with N-acetylglucosamine significantly (p<0.05) exceeded the efficacy of the oral combination. Under its influence, there was an increase in glomerular filtration and urinary excretion of creatinine and urea. It indicates the normalization of the kidney functional state and nitrogen metabolism. Moreover, this combination was significantly (p<0.05) superior to the Corvitin effect by the efficacy level.
Conclusions. In conditions of the end-stage renal failure in rats the injection combination of quercetin with N-acetylglucosamine was highly effective. It allows considering this combination to be a promising medicine for treating CKD at the IV-V stages.
