Popis: Toxicity measurements of the schistosomicide TWSb indicate this trivalent antimonial to be well tolerated by rats given daily intramuscular injections of 100 mg/kg, 10 mg/kg, and 1 mg/kg for 15 weeks; these doses are equivalent to daily administration of 25 mg/kg, 2.5 mg/kg, and 0.25 mg/kg of antimony. The parameters measured include observation of general health, blood counts, and gross and microscopic examination of the tissues. Single intramuscular doses of 100 mg/kg or 1 mg/kg of TWSb produced high levels of antimony in serum and tissues after 1 hour, and significant amounts were still present after 144 hours. The peak concentrations of antimony in intestines occurred at a later time interval than observed in serum, liver, or kidneys, suggesting that the drug is excreted via the biliary route at a relatively slow rate.
