internal parasite control agent

Abstract

In order to provide a new parasite control agent such as anthelmintic or antiprotozoal, which has an effective control effect on animal endoparasites that cannot be controlled by conventional anthelmintics or antiprotozoal agents, the present invention provides a general formula An endoparasite control agent in which the heterocyclic carboxamide derivative or its salt shown in (I) is an active ingredient.

Description

technical field [0001] The present invention relates to an agent for controlling endoparasites containing a heterocyclic carboxamide derivative or a salt thereof as an active ingredient, and a method for controlling endoparasites characterized in that the agent is administered orally or parenterally. Background technique [0002] Conventionally, certain carboxamide derivatives are known to have fungicidal activity (for example, see Patent Documents 1 to 13). However, there is no description that the compounds described in this document are effective in expelling or controlling endoparasites parasitic on animals such as mammals and birds. In addition, certain carboxamide derivatives are known to be effective against nematodes that damage crops (for example, see Patent Document 4 or 5), but there is no specific disclosure about the effect against endoparasites that parasitize animals. Furthermore, it has been reported that a compound that inhibits mitochondrial complex II, wh...
