On the other hand, thecombination therapy approach （currently used to retard the selection of parasite strains resistant to individual components of acombination of drugs） has proved to be a success in the combination of sulphadoxine and pyrimethamine, which targets two differentsteps in the folate pathway of malaria parasite. However, after the success of this therapeutic combination, the efficacy of othercombinations of drugs which target different enzymes in a particular metabolic pathway has, apparently, not been reported.
