PG - 15-21 LID - 10.1016/S0210-5705(10)70004-2 [doi] AB - After many years of widespread use, proton pump inhibitors (PPI) have been demonstrated to be relatively safe. The most frequently associated adverse reactions are mild with scarce clinical effects. These agents produce hypergastrinemia but this adverse effect has not been related to the development of malignancies. PPI seem to facilitate certain bacterial infections in the gastrointestinal and respiratory tracts. However, these infections are easily treated and therefore do not limit the prescription of PPI. From the pharmacokinetic point of view, the possibility of interactions with other drugs metabolized by the cytochrome P450 system has been described but these interactions generally seem to have little clinical or therapeutic importance. However, regulatory agencies are currently stressing the hypothetical interaction between PPI (especially omeprazole) and clopidogrel, which reduces the latter's antiplatelet effect. Although this recommendation should be followed, this interaction should be specifically evaluated to determine its clinical effect and the possible alternatives in patients at risk of gastrointestinal bleeding. Lastly, the present article reviews PPI administration in special, currently debated situations, such as in pregnant or breastfeeding women. CI - Copyright (c) 2010 Elsevier Espana S.L.
