[Acute toxicity and the cumulative properties of carfecillin]. 1978

M Z Lidovskiĭ, and I Z Zel'tser, and E K Berezina

Acute toxicity of oral and intraperitoneal carfecillin was studied on different species of laboratory animals, such as albino mice, rats and guinea pigs. The average lethal doses equal to 3040 (2393.7-3860.8) and 1325 (1104.2-1590) mg/kg for oral and intraperitoneal administration respectively allowed the authors to consider the antibiotic as a low toxic substance under conditions of a single administration. Higher toxicity of carfecillin as compared to carbenicillin may be due to production of free phenol on carfecillin hydrolysin in the animal organism. The different laboratory animals of both sexes had almost the same sensitivity to the antibiotic. On repeated administration of carfecillin to the albino mouse stomach (in portions of LD50) no cumulative properties of the antibiotic were observed.
