"Essential medicines are a carefully curated list of pharmaceuticals that address the most critical health needs of a population. Compiled by health experts and organizations such as the World Health Organization (WHO), this list comprises medications considered indispensable for the provision of primary healthcare and the treatment of prevalent diseases. The selection process prioritizes efficacy, safety, and cost-effectiveness. These medicines are deemed essential because they fulfill the most fundamental healthcare requirements and are intended to be available within the context of robust healthcare systems. The list spans a wide range of therapeutic classes, encompassing antibiotics, analgesics, antiretrovirals, and vaccines, among others. Access to essential medicines is regarded as a fundamental human right, as outlined by international health initiatives. Governments and healthcare organizations use the Essential Medicines concept to guide health policy, procurement strategies, and resource allocation, ensuring that even resource-limited settings can provide necessary and cost-effective treatments. By promoting the availability and affordability of these medicines, the Essential Medicines concept aims to enhance healthcare equity and contribute to global efforts to improve public health outcomes."
