Global pharmaceutical sales rankings place oncology blockbusters like pembrolizumab, marketed under the brand name Keytruda, alongside high-demand metabolic medications such as semaglutide and tirzepatide among the world's top-selling prescription drugs. These advanced medications generate tens of billions of dollars in annual worldwide revenue, driven by expanding clinical indications, widespread global adoption, and high patient demand for chronic disease management and advanced cancer therapies. Over-the-counter mainstays like generic pain relievers such as aspirin and ibuprofen remain the most widely purchased medications globally by sheer unit volume.
