The plasma kinetics of doramectin and moxidectin were evaluated in zebu Gobra under field conditions after subcutaneous administration of 0.2 mg kg−1 of commercially available formulations for cattle. The results indicate that the absorption of moxidectin from the site of injection was significantly faster (absorption half-life [t1/2ab]=0.7 day) than that of doramectin (t1/2ab=3.1 days). Moxidectin peak plasma concentration (Cmax) was reached significantly earlier (tmax=0.4 day) compared with that of doramectin (tmax= 5.3 days). No differences in Cmax values were observed; the area under the concentration–time curve was higher for doramectin (475 ng day ml−1) compared with moxidectin (198 ng day ml−1), while the mean residence time was longer for moxidectin (13.4 days) compared with doramectin (9.4 days). These results obtained give interesting information on doramectin and moxidectin pharmacokinetics in zebu Gobra, which show a similar pharmacokinetic profile as in other cattle.
