ACT With Chloroquine, Amodiaquine & Sulphadoxine-Pyrimethamine in Pakistan
Chloroquine resistant falciparum malaria in Pakistan is prevalent in every malarious area examined. Resistance to the favoured second-line treatment, sulphadoxine-pyrimethamine S/P is rising fast. To avert a repetition of the resistance catastrophe that occurred in SE Asia it is critical to preserve the effective life of SP by using it in combination with artesunate. Efficacy of ACT with artesunate in combination with chloroquine, SP or amodiaquine for treatment of malaria (falciparum or vivax) will be examined in malaria patients in Pakistan.
