Abstract

P-glycoproteins (P-gps) play an important role in the sensitivity of nematodes to anthelmintic drugs. They have been implicated in a number of anthelmintic resistances, particularly for macrocyclic lactone drugs. Hence, inhibition of nematode P-gps has been suggested as a means of reversing some types of anthelmintic resistance. The present study aimed to investigate the ability of the most-recently developed group of P-gp inhibitors (the so-called 'third generation' of inhibitors) including tariquidar, zosuquidar and elacridar, to increase the sensitivity of Haemonchus contortus larvae to various anthelmintics (ivermectin, levamisole and thiabendazole) in vitro. We compared these compounds ..
