Toxicity assessment of sulpiride as the basis of its hygienic standardization
Toxic properties of sulpiride were studied with an aim of its hygienic standardization. LD50 of sulpiride in administration into the stomach of male rats and mice is 7200 and 3400 mg/kg, for female rats and mice - 6000 and 2300 mg/kg. It refers to substances of hazard Classes 3, 4. No significant differences were noted in the species and sex sensitivity of animals to a substance. In intraperitoneal administration LD50 for male rats is 220 mg/kg, for female rats - 150 mg/kg. It has a pronounced cumulation ability, cumulation coefficient: Kcum equals 2.9. It has not a local irritant effect on the skin. There were no identified skin-resorptive and sensitizing effects. It causes a slight irritant effect on the mucous membranes of the eyes. It has a toxic effect on the central nervous system, liver, kidneys. Threshold of acute inhalation action is - 63.5mg/m <sup>3</sup>. Occupational safety level of exposure to sulpiride in the working area air is 0.5 mg/m <sup>3</sup>.
