P0616 – Bone Density and Fracture Risk in Vonoprazan Users: A Stratified Population-Based Analysis

Sunday, October 26, 2025 | 3:30 PM – 7:00 PM PDT | Exhibit Hall

Author Insight from Morgan Starkey, MD

What’s new here and important for clinicians?
While our study found that vonoprazan does not significantly increase the risk of bone density loss in the general population, subgroup analysis showed that female users faced a significantly higher risk compared to males. Age did not play a significant factor, but those older than 50 had a slightly higher risk. 

Most importantly, even though there was no overall significant link between vonoprazan and reduced bone density, users who developed osteopenia or osteoporosis experienced a notably higher rate of fragility fractures. This should be taken into serious consideration in starting or continuing use in postmenopausal women, particularly those with already low bone density. 

What do patients need to know?
While vonoprazan is superior in the treatment of multiple upper gastrointestinal issues, use should be limited to minimal effectiveness time in postmenopausal women to reduce the risk of bone thinning and life-threatening fractures.
