With these quotations, I would like to introduce the fourth installment of the ‘‘Paradigm Shifts in Perspective’’series, which features a personal retrospective by George Sachs, one of the most prominent clinician-investigators in the quest to discover effective gastric antisecretory drugs. Fewer physicians each year recall the scourge that was peptic ulcer disease prior to the advent of today’s antisecretory therapy. As a GI fellow in 1979, much of our training was geared toward recognizing and treating the morbid effects of peptic ulcer surgery and the use of antacids and diets to treat ulcers. The ‘‘antisecretory era’’started with the original report of the H2 receptor antagonist metiamide in 1973 by Nobel Laureate James Black [1], clinical approval of cimetidine in the UK in 1976, the initial report of the antisecretory properties of the original proton pump inhibitor (PPI) omeprazole published in 1981 [2], culminated by the approval of omeprazole in 1989. Antisecretory drugs have revolutionized the treatment of acid-peptic disease, with the near abolition of surgical peptic ulcer treatments [3] and the effective treatment of reflux-related mucosal injury and symptoms. Although adverse effects of PPIs have received much attention in the lay press and in the medical literature, the frequency of and magnitude of these effects are quite low relative to the hundreds of millions of doses taken [4, 5]. Indeed, PPIs are one of the greatest advances to our field of gastroenterology in the second half of the twentieth century and arguably one of the paramount developments in all of medicine during that period.In the accompanying article, George Sachs (Fig. 1) spins a personal, compelling, fascinating, and insightful glimpse into the world from which antisecretory drugs emerged. Dr. Sachs first described the correct mechanism of H+ secretion by the gastric H+, K+ ATPase [6], following descriptions by other scientists of its hydrolytic activity [7, 8]. At that time, George was clearly positioned at the intersection of scientific world with his scholarly and innovative articles and the pharmaceutical world in which he interacted freely with the scientists and management of SmithKline, which developed cimetidine, and Astra AB, which developed omeprazole. George’s considerable scientific acumen, keen perspective, and quick mind enabled him to convince Astra to develop omeprazole clinically, claiming that its sales would exceed $ US 1 bn. How wrong he was, since the annual worldwide sale of PPIs has exceed $ US 20 bn in the last 10 years, with cumulative sales since approval in 1989 likely exceeding $ US 400 bn.[9]. In terms of scientific impact, over 30,000 articles have been published about PPIs and over 10,000 about the gastric proton pump since their original descriptions, a paradigm
