Antimalarial Drugs with Quinoline Nucleus and Analogs. In Malaria-Transmission, Diagnosis and Treatment.

Quinoline core antimalarials are a major class used for the management of uncomplicated malaria in combination with artemisinin derivatives. Moreover, despite its adverse effects, Quinine remains the reference molecule in the treat-ment of cerebral malaria due to Plasmodium falciparum. This class also contains molecules such as Mefloquine used in the prevention of malaria. In addition, synthetic derivatives are more manageable with greater therapeutic margins and fewer adverse effects. They have an interest in avoiding the spread of resistance, especially with derivatives possessing gametocytocidal activities. With the presence of a chloroquine-resistant strain of Plasmodium, the use of synthetic derivatives as monotherapy is prohibited to avoid the spread of resistance in this class. In this chapter, we propose to present the class of antimalarials with a quinoline nucleus under its pharmacochemical aspects as well as the prospects for its development to preserve and improve the effectiveness of its representatives in the management of malaria.

Evaluation of the Quality of Artemether-Lumefantrine-based Antimalarials from the Illicit Ivorian Market in West Africa

Background: Counterfeit and substandard medicines represent a severe public health issue, particularly in developing nations where their prevalence exacerbates disease resistance and economic challenges. In addition, many deaths in Côte d'Ivoire could be avoided each year if the drugs prescribed against malaria were compliant with regulations and able to effectively treat the disease. Objective: This study aimed to evaluate the quality of artemether-lumefantrine antimalarial combination on the Ivorian illicit market using the GPHF-Minilab® kit. Methods: A total of 15 samples were analyzed through visual inspection, disintegration testing, and TLC for qualitative and semi-quantitative assessments. Results: The findings reveal significant non-conformities, including 20% of samples lacking manufacturer information, 7% without accompanying instructions, and 20% with physical degradation. 93% of samples disintegrated within 30 minutes, meeting pharmacopoeial standards. One sample exceeded the recommended time, indicating substandard manufacturing. Most samples (67%) met active ingredient quantity requirements, but 26% were underdosed, and 7% were overdosed, highlighting manufacturing and storage deficiencies. In view of these results, it appears that the Artemether-lumefantrine drugs seized on the illegal market in Côte d'Ivoire are not of good quality. Conclusion: The GPHF-Minilab® proves a reliable tool for identifying substandard and counterfeit drugs in resource-limited settings, though further validation is required for broader applications. These results underscore the need for stringent regulatory frameworks, public education, and expanded quality control initiatives.
