  • Title: Effect of oral dosing vehicles on the developmental toxicity of flubendazole in rats.
    Author: Yoshimura H.
    Journal: Reprod Toxicol; 2003; 17(4):377-85. PubMed ID: 12849847.
    Abstract:
    Flubendazole was suspended in deionized water or olive oil and administered by gavage once daily to pregnant rats on Days 8-15 of pregnancy to examine if the embryolethal and teratogenic doses were affected by the vehicles used. Flubendazole in olive oil caused a statistically significant increase in embryolethality at doses of 7.83 mg/kg per day and higher, with complete resorption in all dams at 31.33 mg/kg per day. When flubendazole was suspended in deionized water, a significant increase in embryolethality occurred only at a maternal dose of 125.32 mg/kg per day. The proportion of litters with anomalous fetuses was significantly increased at doses of 31.33 mg/kg per day and above when flubendazole was administered in deionized water, but increased at doses at four times lower when flubendazole was administered as in olive oil. Administered as a single dose in olive oil on any one of Days 6-12 of pregnancy, a flubendazole dose of 31.33 mg/kg caused significant increases in embryolethality and decreased fetal body weights on Days 7-9, with an 82.7% incidence of embryolethality on Day 8, with complete resorption in 5 of the 8 dams. The critical periods for teratogenic effects were between Days 8 and 11 of pregnancy, with Day 9 being the most critical. Fetuses with gross, skeletal, or internal anomalies were seen in dams given a single dose of as low as 7.83 mg/kg.
