Through studying interactions between receptors on cells and chemicals in the bloodstream that attach to them, Black developed the first of the beta-blocking drugs, to relieve angina pectoris. He used a similar approach to develop drugs for stomach and duodenal ulcers. He shared a 1988 Nobel Prize for Physiology or Medicine with George H. Hitchings and Gertrude Elion .
