WHO today published the new edition of its Model Lists of Essential Medicines and Essential Medicines for Children, which include new treatments for various cancers, insulin analogues and new oral medicines for diabetes, new medicines to assist people who want to stop smoking, and new antimicrobials to treat serious bacterial and fungal infections. The listings aim to address global health priorities, identifying the medicines that provide the greatest benefits, and which should be available and affordable for all. However, high prices for both new, patented medicines and older medicines, like insulin, continue to keep some essential medicines out of reach for many patients.
