Drugs used to treat acid reflux linked to heightened risk of premature death
Drugs used to treat acid reflux have been linked to a heightened risk of premature death in a new study.
Proton pump inhibitors (PPIs) reduce the amount of acid made by the stomach and are used to treat acid reflux and stomach ulcers.
A team of US researchers performed a longitudinal observational study on data from the US Department of Veterans Affairs.
Over a follow-period of almost six years, they examined data on 3,288,092 people to compare users and non-users of PPIs.
Their study, published in the journal BMJ Open, also examined data on 349,312 people to compare risk of death between those taking PPIs with those taking another type of drug used to dampen down acid production called histamine H2 receptor antagonists, or H2 blockers.
They also looked at data on 2,887,030 people to assess risk of premature death for PPI users compared to PPI and no H2 blockers.
Compared with H2 blocker use, PPI use was associated with a 25% heightened risk of death from all causes.
They also found an increased risk of death when considering PPI use versus no PPI and an increased risk from PPI use versus no PPI and no H2 blocker use.
The study is an observational one, so no firm conclusions can be drawn about cause and effect, and the authors stress that the findings may not be extended generally because the majority of participants were older, white male veterans.
But they still caution that: "Limiting PPI use and duration to instances where it is medically indicated may be warranted."
