Large case-control studies have suggested a possible relationship between the use of proton-pump inhibitors (PPIs) and an increase in osteoporosis and fractures. However, the strength of this association varies among studies (JW Gastroenterol Jul 30 2010).
Investigators in Canada suggest that demonstrating a link between PPI use and a loss of bone mineral density (BMD) would support the idea that PPIs increase risk for fracture. To identify this possible link, the researchers assessed prospectively collected data from the Canadian Multicentre Osteoporosis Study, which involved a population-based sample of patients who provided medical and medication history and underwent BMD testing of the lumbar spine, femoral neck, and total hip at the beg…
