Mefloquine is an antimalarial drug used to treat and prevent malaria. However, during its manufacturing process, certain impurities may be formed, which can potentially affect the safety and efficacy of the drug. These impurities can be organic or inorganic in nature and can arise from various sources including starting materials, reagents, solvents, and processing equipment. Therefore, it is important to closely monitor and control the levels of these impurities during the production of mefloquine to ensure the drug's quality and safety.
