Determination of toxicological characteristics of a complex antiemeric drug based on maduramycin and nicarbazine

Abstract

The aim: to determine the parameters of acute toxicity of the preparative form of an antiemeric agent based on maduramycin and nicarbazine for white mice, white rats and guinea pigs with a single oral administration.
 Materials and methods. Determination of acute toxicity of the formulation by oral administration was performed on 48 adult male mice, 48 adult nonlinear male rats, 48 adult male guinea pigs. To conduct an experiment on the principle analogues were formed seven experimental and one control group, 6 animal each. The dose of the formulation was calculated individually based on body weight values. It should be noted that the total volume of the emulsion of the formulation administered orally is not exceeded 1.0 cm3per 100 gram b. w.
 Results. Toxicometric parameters of the formulation were calculated by the method of least squares for probit analysis of mortality curves. It was found that the LD50 of the preparative form of antiemeric agent for white mice for a single oral administration is 238.05±28.08 mg/kg, LD16 – 128.71 mg/kg, LD84 – 347.39 mg/kg, LD100 - 402, 06 mg/kg body weight, respectively.
 LD50 of the preparative form of antiemeric agent for white rats with a single oral administration is 260.51±28.83 mg/kg, LD16 – 148.39 mg/kg, LD84 – 372.65 mg/kg, LD100 – 428.71 mg/kg body weight, respectively.
 LD50 of the preparative form of antiemeric agent for guinea pigs for a single oral administration is 275±21.12 mg/kg, LD16 – 201.74 mg/kg, LD84 – 348.25 mg/kg, LD100 – 384.88 mg/kg body weight body respectively.
 Conclusions. According to SOU 85.2-37-736: 2011 "Veterinary drugs. Determination of acute toxicity” preparative form of a complex antiemeric agent based on maduramycin and nicarbazine on the degree of toxicity can be attributed to moderately dangerous substances (3rd hazard class)
