[Comparative study of proton pump inhibitors].

Proton pump inhibitors (PPI) have influenced dramatically the management of acid-related disorders in recent years. They all have a broadly similar mechanism of action. There are some differences however, between the PPIs in their pharmacokinetics, pharmacodynamics, clinical efficacy, and potential for drug interactions. Although the individual PPI have similar efficacy in many cases, differences between them should be considered when choosing a treatment regimen. Further clinical trials are needed to assess the clinical importance of these differences, as well as to assess whether the potential advantages result in clinical benefit for patients with acid-related disorders.
