PLASMA EVALUATION FOR IVERMECTIN IN LLAMAS (LAMA GLAMA) AFTER STANDARD SUBCUTANEOUS DOSING

Abstract

Plasma levels of the parasiticide ivermectin were studied by high-performance liquid chromatography in five llamas (Lama glama) after single 200 microg/kg s.c. injections. Ivermectin levels were undetectable in plasma samples drawn up to 4 wk after injection, suggesting that the dosage used was insufficient to reach therapeutic concentrations in this species.
