N2 - This article reviews the literature dealing with the effects of composition and quality of diet and feeding time on the pharmacokinetics and efficacy of some anthelmintic drugs in ruminants. Studies have suggested that greater availability, and therefore improved anthelmintic activity, is possible through temporary feed restriction. It is also recommended that anthelmintic drugs should not be given to animals whilst they are maintained on large feed intakes, particularly of lush pasture that promotes rapid gastric transit, as this may reduce drug availability and anthelmintic efficacy. Generally, feeding animals low-quality fibrous diets reduces the passage rate of digesta and allows more time for absorption of several anthelmintic drugs and their metabolites from the gut. Some kinetic data of drugs given to animals on such diets may be slightly different, but this does not necessarily indicate alteration of the dosages of the anthelmintic drug. Nonetheless, due consideration should be given to anthelmintic dosages under various dietary regimes if optimum efficacy is to be achieved at all times.
