The observed changes of P. falciparum sensitivity to artemisinin leads to the intensification of early detection as well as treatment monitoring in malaria infection. It is widely accepted that the development of resistance can be delayed by the use of combination therapy, especially artemisinin-based combination therapies (ACTs). The resistance problem is considered extremely serious and as the consequence WHO has recommended that all monotherapy for malaria should be stopped Current WHO guideline recommends the drug combination regimens using ACT with effective partner medicines to decrease the risk of development or spreading of artemisinin resistance.
