Describe the purpose of essential medicines lists (EMLs) in health systems.

• B. Standardize hospital floor plans.
• C. Identify priority medicines for a health system.
• D. Set global drug prices.

Answer: (C)

Essential medicines lists identify priority medicines for a health system. They are designed by considering the health needs of the population, along with evidence on how well a medicine works, its safety, and its cost-effectiveness. By selecting a core set of medicines that address the most important conditions, the list helps ensure those medicines are affordable, available, and of good quality. This focus guides procurement, budgeting, and the shaping of national formularies and reimbursement decisions, supporting rational use and equitable access across settings. Updates reflect new evidence and changing disease patterns, and the lists are often aligned with national treatment guidelines to keep care consistent. These lists aren’t about excluding medicines from formularies, nor are they about standardizing hospital floor plans or setting global drug prices; those functions come from separate processes.
