The WHO Essential Medicines List focuses on selecting medicines that address the most important public health needs, ensuring that these treatments are safe, effective, and cost-efficient. This helps healthcare systems worldwide to prioritize resources and improve access to vital medications. By emphasizing cost-effectiveness and clinical relevance, the list supports rational prescribing and equitable healthcare delivery, particularly in resource-limited settings. The aim is not to promote expensive drugs or marketing interests but to guide countries in meeting essential health requirements efficiently.
