The small British company was sometimes called Glaxo University, because it conducted important pharmaceutical research that rarely resulted in profitable drugs. Then the scientists at Glaxo Laboratories created a molecule they called ranitidine, and in 1978 the company was granted a US patent. The molecule was new, but not novel. The scientists had, as scientists sometimes do, looked for a way to mimic the success of an established drug—in this case, one that healed ulcers and could be used to treat heartburn. They developed ranitidine quickly, and the US Food and Drug Administration reviewed it quickly. Glaxo gave it the brand name Zantac.
