Malaria has been a major public health problem worldwide. The burden of malaria has been reduced by the adoption of Artemisinin-Combination Therapy (ACT) followed by primaquine dosage in malaria-endemic countries. However, evidences of non-adherence behavior lead to the discovery of antimalarial drug adherence to ensure a successful and satisfactory treatment of ACT, since it is the only available antimalarial drugs against asexual form of the parasite. Unstandardized questionnaires and limited effective alternative approaches have been the major obstacles to measure adherence. With rapid development of pharmacokinetic research, public health researchers can adopt the approach to measure adherence. Notwithstanding, the current structured questionnaire has explained in detail that the measurement and classification of adherence have produced satisfactory results. However, it is subject to social desirability bias. Therefore, in this review, we offer a new strategy combining structured questionnaire and drug metabolite as a novel consensus which eliminates biases. A new classification of adherence and graphical representation of practical strategy and other important factors are provided in this review. Thus, it initiates further works to conduct an intervention program to increase adherence level. Additionally, adherence behavior prevents the development of drug resistance and its spread, increases satisfactory cure rate and inhibits transmission by eliminating gametocyte inside host’s body.
