Good-quality antimalarials are crucial for the effective treatment and control of malaria. A total of 7,740 individual and packaged tablets, ampoules, and syrups were obtained from 60 randomly selected public (N = 35) and private outlets (N = 25) in Afghanistan. Of these, 134 samples were screened using the Global Pharma Health Fund (GPHF) MiniLab® in Kabul with 33/126 (26%) samples failing the MiniLab® disintegration test. The quality of a subsample (N = 37) of cholorquine, quinine, and sulfadoxine/pyrimethamine tablets was assessed by in vitro dissolution testing following U.S. Pharmacopeia (USP) monographs at a bioanalytical laboratory in London, United Kingdom. Overall, 12/32 (32%) samples of sulfadoxine/pyrimethamine and quinine were found not to comply with the USP tolerance limits. Substandard antimalarials were available in Afghanistan demonstrating that continuous monitoring of drug quality is warranted. However, in Afghanistan as in many low-income countries, capacity to determine and monitor drug quality using methods such as dissolution testing needs to be established to empower national authorities to take appropriate action in setting up legislation and regulation.

Introduction: Haiti is on the verge of possibly eliminating malaria, an endemic parasitic infection primarily caused by Plasmodium falciparum on the island of Hispaniola. Owing to its associated morbidity and mortality, malaria is a leading public health priority in Haiti. This scoping review aims to identify the scope of research on access and coverage of malaria surveillance, diagnosis, and treatment in Haiti in the elimination setting.

Background: Over the past years, there has been a growing concern that a considerable amount of anti-malarial supply in the underdeveloped world particularly in the private sector, is of poor quality. The World Health Organization (WHO) has received about 1500 reports that mentions instances of substandard and falsified products since 2013. The majority of the reports concerned antibiotics and anti-malarials.

Background: There is growing concern in sub-Saharan Africa that poor-quality antimicrobial medicines may negate management of infectious diseases of public health importance should they fail to meet the set criteria of quality, safety and efficacy.
Objectives: The objective was to ascertain the quality of antiretroviral, antimalarial and antituberculosis medicines supplied and available in the public health sector in Zambia.
Design: A descriptive cross-sectional study was conducted involving the analysis of data from the continuous routine in-country post-marketing surveillance programme in Zambia that assessed the quality of antiretroviral, antimalarial and antituberculosis medicines supplied to public healthcare facilities between January 2018 and June 2023.
