As a class, PPIs are among the safest of pharmacologic agents. In the last yearsconcerns have risen regarding potential of adverse events due to PPI use. These inclu<strong>de</strong> cancerrisk (stomach and colorectal cancer), infection risk (pneumonia, Clostridium difficile associateddiarrhea, small intestinal bacterial overgrowth, spontaneous bacterial peritonitis, interstitialnephritis), metabolic effects on bone <strong>de</strong>nsity with osteoporotic fractures, alteration of absorptionof vitamins and minerals and the pharmacodynamic interaction with the metabolism of othermedications by the hepatic cytochrome P450 enzyme systems (e.g., clopidogrel). Almost theentire evi<strong>de</strong>nce base regarding the safety of PPI therapy is composed of retrospective nonrandomizedstudies that <strong>de</strong>monstrate association but not causality and are limited by potentialconfounding factors. There is no evi<strong>de</strong>nce to support any benefit of changing existing clinicalpractice for preventing any of the potential adverse effects associated with PPI therapy. Therefore,in patients with appropriate indications for PPI, we should avoid continuous and high-dosetherapy, consi<strong>de</strong>ring on-<strong>de</strong>mand therapy in suitable patients and step-down strategy.KEY WORDS: PROTON PUMP INHIBITORS; PPI; GASTRIC CANCER; OSTEOPOROSIS;CLOSTRIDIUM DIFFICILE; CLOPIDOGRELSHORT TITLE: Proton pumps inhibitors: benefits & risksInhibitorii pomei <strong>de</strong> protoni: beneficii şi riscuriHOW TO CITE: Mihai C, Dranga M, Ba<strong>de</strong>a M, Ne<strong>de</strong>lciuc O, Mihai C.
