title: [Evidence and uncertainties on the clinical use of proton pump inhibitors].
abstract: Proton pump inhibitors (PPI) are the most potent and effective drugs for the control of gastric acid secretion and constitute one of the most widely prescribed pharmacological groups worldwide. The safety and efficacy of PPI have been demonstrated in clinical practice and these drugs are currently the treatment of choice in peptic ulcer diseases, Helicobacter pylori infection, gastroesophageal reflux disease, nonsteroidal antiinflammatory drug gastropathy and functional dyspepsia. However, despite the excellent pharmacological profile of current PPI, their rapidity of action may be insufficient in some diseases, 24-hour acid inhibition is not always achieved and - to a greater or lesser extent depending on the distinct molecules of the PPI - there is interindividual variability in gastric antisecretory efficacy, depending on genetic polymorphism of CYP2C19, which could affect individual metabolism of the distinct PPI. New generations of these drugs will probably eliminate these deficiencies.
