Zolvix® Plus is a combination drench that combines monepantel, the only member of the amino-acetonitrile derivative (AAD or 'orange') class of anthelmintics, with abamectin. As short-acting, broad spectrum drenches with different modes of action, monepantel and abamectin are ideal combination partners. Using drenches in appropriate combination is widely recognized as being beneficial in delaying the development of resistance to drench actives.
