Malaria, a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes, remains a major health challenge, particularly in less developed countries. According to the World Health Organization (WHO), there were an estimated 229 million cases of malaria worldwide in 2019, resulting in roughly 409,000 deaths, most of them children under the age of five in sub-Saharan Africa. The persistent struggle to combat this disease fosters a continuous search for new, effective, and safer treatment options.
Recently, a promising development in the fight against malaria has emerged: MEFAS, an innovative hybrid drug composed of mefloquine and artesunate. MEFAS offers the synergistic effects of both drugs while aiming to reduce their individual risks and side effects. As potential treatment breakthroughs like MEFAS come to light, the scientific community delves into rigorous research to ensure these innovations are, above all, safe for administration. A recent study, published in the journal Drug and Chemical Toxicology (DOI: 10.1080/01480545.2019.1607371), delves into the acute toxicity assessment of MEFAS and its components.
The Investigation of MEFAS Safety
The study conducted by a team of researchers led by Daniely Alves de Lima and her colleagues from the Laboratory of Preclinical Research of Natural Products at Paranaense University, Brazil, assessed the acute toxicity of MEFAS compared to its precursors artesunate, and mefloquine. Through their research, they aimed to understand better the safety profile of this new potential antimalarial compound.
In this animal study, a total of 42 female Swiss mice were utilized for the experiments and were divided into seven groups, with each group receiving different concentrations of the MEFAS compound and its individual constituents. The objective was to determine any adverse effects or toxicities associated with the dosage levels, which can prove crucial in the informed development of MEFAS as a human medication.
Study Findings and Their Implications
The study’s findings indicated that the hybrid salt MEFAS exhibited lower toxicity in the animal model compared to the administration of its individual components at equivalent doses. This suggests that MEFAS could offer a safer alternative to current antimalarial regimens, potentially decreasing the risk of side effects associated with its constituent drugs.
These results bolstered the notion that a combination drug therapy could be the key to more effective and less toxic treatment strategies for malaria. The research performed by de Lima and her colleagues represents an important step forward in validating the safety of MEFAS, fortifying the groundwork for subsequent clinical trials that are needed to assess MEFAS’s efficacy and safety in humans.
The Broader Impact on Public Health
With malaria continuing to claim hundreds of thousands of lives annually, the development of new treatments like MEFAS is vital. By potentially offering a safer and low-cost option, MEFAS could contribute significantly to global efforts to manage and eventually eradicate the disease, especially in regions with limited healthcare resources.
The study’s outcomes also underscore the necessity for continued investment in research and development of antimalarial drugs, recognizing the evolving resistance patterns of Plasmodium—the parasite responsible for malaria—and the adverse effects associated with long-standing treatments.

In conclusion, the study by de Lima and colleagues is one of many vital efforts in paving the way for safer and more effective antimalarial treatments. MEFAS, as an innovative combination of artesunate and mefloquine, demonstrates lower toxicity in preliminary studies and has the potential to change the landscape of malaria treatment. However, further research and clinical testing are necessary to validate its benefits and establish its place in the global fight against this devastating disease.
