RESUMEN
BACKGROUND: Proton pump inhibitors (PPIs) are one of the most prescribed drugs in the world. Frequent use and long-term maintenance of these drugs drew the attention of researchers for sporadic adverse effects reports. OBJECTIVE: The purpose of this narrative review is to discuss appropriate data and causality related to these adverse events and PPIs. METHODS: A narrative review was conducted by systematizing information about safety and adverse events on PPIs from 2015 to 2020. A structured search on Pubmed was performed to identify systematic reviews and meta-analysis investigating the following situations: a) gastric cancer; b) micronutrients deficiency; c) acid rebound; d) infections; e) fractures; f) dementia; g) kidney disease; and h) sudden death and cardiovascular changes. RESULTS: Recent studies have potentially associated PPIs with some adverse events as osteoporosis-related fractures. There are also reports of intestinal infections, including Clostridium difficile, besides poor vitamins absorption and minerals such as vitamin B12, magnesium, and iron. Furthermore, there are some dementia, pneumonia, kidney disease, myocardial infarction, and stroke reports. For kidney diseases, studies consistently suggest that the use of PPI may be associated with an increased risk of adverse kidney events, especially in the elderly, with long-term PPI use and pre-existing kidney disease. Another additional question is whether chronic PPI use would also lead to the onset of gastric cancer. The abrupt discontinuation of PPIs is also related to increased gastric acid production above pre-PPI treatment levels; this phenomenon is called acid rebound. CONCLUSION: The key to mitigate adverse effects is the rational use of PPIs at the lowest effective dose and in the shortest possible duration. Although these adverse effects have a potential clinical impact, their causal association is still subject to validation.

RESUMO: Contexto: Os inibidores da bomba de prótons (IBPs) são um dos medicamentos mais prescritos no mundo. O uso frequente e a manutenção a longo prazo dessas drogas chamaram a atenção dos pesquisadores devido aos relatos esporádicos de efeitos adversos. Objetivo: Esta revisão narrativa tem o objetivo de discutir os dados e a causalidade relacionada a esses eventos adversos e o uso de IBPs. Métodos: Uma revisão narrativa foi conduzida através da sistematização das informações sobre segurança e eventos adversos de IBPs de 2015 a 2020. Uma busca estruturada na base de dados PubMed foi realizada visando identificar revisões sistemáticas e meta-análises investigando as situações a seguir: a) câncer gástrico; b) deficiência de microelementos; c) acidez de rebote; d) infecções; e) fraturas; f) demência; g) doença renal; e h) morte súbita e alterações cardiovasculares. Resultados: Estudos recentes têm potencialmente associado IBPs a alguns eventos adversos, como fraturas relacionadas à osteoporose. Também há relatos de infecções intestinais, incluindo Clostridium difficile, além de má absorção de vitaminas e minerais como vitamina B12, magnésio e ferro. Além disso, há alguns relatos de demência, pneumonia, doença renal, infarto do miocárdio e acidente vascular cerebral. Na doença renal, os estudos sugerem consistentemente que o uso de IBPs pode estar associado a um risco aumentado de eventos renais adversos, especialmente em idosos, com o uso de IBPs a longo prazo e doença renal preexistente. Outra questão adicional é se o uso crônico de IBPs também levaria ao aparecimento de câncer gástrico. A descontinuação abrupta de IBPs também está relacionada ao aumento da produção de ácido gástrico acima dos níveis de tratamento pré-IBPs; este fenômeno é conhecido como rebote ácido. Conclusão: A chave para mitigar esses efeitos adversos é o uso racional de IBPs na menor dose efetiva e com a menor duração possível. Embora esses efeitos adversos tenham um impacto clínico potencial, sua associação causal ainda está pendente de uma validação.
