Combined use of ivermectin and triclabendazole in sheep: In vitro and in vivo characterisation of their pharmacological interaction
This study evaluated the pharmacokinetic properties of ivermectin (IVM) and triclabendazole (TCBZ) given either separately or co-administered to sheep. Corriedale sheep received IVM alone, TCBZ alone or a combination of IVM and TCBZ intravenously. Ivermectin elimination was delayed and its plasma av...

| Sumario: | This study evaluated the pharmacokinetic properties of ivermectin (IVM) and triclabendazole (TCBZ) given either separately or co-administered to sheep. Corriedale sheep received IVM alone, TCBZ alone or a combination of IVM and TCBZ intravenously. Ivermectin elimination was delayed and its plasma availability was 3-fold higher when co-administered with TCBZ. Similarly, plasma concentrations of TCBZ and its metabolites were influenced by the co-administration of IVM. Higher peak plasma concentrations of TCBZ metabolites were detected after the co-administration of TCBZ and IVM compared to those obtained following TCBZ treatment in isolation. Complementary in vitro assays were carried out to assess the influence of TCBZ on the P-glycoprotein-mediated intestinal transport of IVM, using the everted gut sac technique. Enhanced accumulation of IVM in the intestinal wall occurred after co-incubation with TCBZ. |
