Abstract: Inhibitors of the sodium-hydrogen exchanger are suitable on their own or in combination with other classes of active compound for the production of a medicament for the treament of diseases which are caused by protozoa; thus of diseases which are caused by animal- and human-pathogenic protozoa, such as by intracellularly active parasites of the classes Apicomplexa and Zoomastigophorea, in particular trypanosomes, plasmodia (malaria pathogens), leishmanias, babesias and theilerias, cryptosporidiidae, sarcocystidae, amoebae, coccidia and trichomonads.
