[Renoprotective efficacy of different doses of statins in experimental acute renal failure]

The effect of three statins (atorvastatin, lovastatin, simvastatin) on the renal function under conditions of experimental acute renal failure in rats was studied. The relatively effective doses were found to possess the most considerable renoprotective properties. All the statins were established to cause the restoration of functional activity of the kidneys under conditions of experimental rhabdomyolytic acute renal failure at various doses, but with the dose of 20 mg/kg they showed the most significant improvement in key indices of kidney function: an increase in diuresis by an average of 32% and glomerular filtration rate by an average of 90%, reduction of proteinuria in more than twice. At the same time, in the animals with acute renal failure the level of creatine phosphokinase was increased by 141%. However, the activity of blood plasma creatine phosphokinase of all animals treated with statins was 14% higher than in the intact control, indicating the minor myotrphic activity of statins in selected mode of administration. Thus, the use of 20 mg/kg dose is the most reasonable from the standpoint of renoprotective efficacy and safety.
