[Ways and methods of searching for new anthelmintics].

The ways of searching for new anthelminthic agents among diverse chemical compounds are analysed. The most promising chemical groups are presented. It is recommended to test every drug using as many as possible experimental models. For drug screening it is advisable to apply a multi-stage investigation method as the most economic and perspective one. The drug selection technique, experimental study procedure and ways of increasing anthelminthic efficiency are outlined.
