The World Health Organization’s Model List of Essential Medicines is a core guidance document that helps countries prioritize key, affordable medical products recommended for widespread availability throughout the health system. Established in 1977, the list serves as a standard template for governments to select medicines that address local public health needs and to develop national essential medicines lists.
