Proton pump inhibitors are widely used in the treatment of acid-related diseases because they are considered to be effective and safe. In the past 10 years the use of proton pump inhibitors increased by over three folds, which is not associated with the increased prevalence of acid-related diseases obviously. However, like any other drugs, they have potential side effects. In recent years many studies have been published about the correlation between long-term proton pump inhibitor therapy and the increase of bone fractures. Most studies showed that long-term proton pump inhibitor therapy moderately increased fracture risk. The underlying mechanisms of increased number of bone fractures are not clarified yet. However, chronic acid suppression caused by long-term proton pump inhibitor therapy may play a crucial role in decreased absorption of calcium and vitamin B12 and, therefore, indirectly affecting the bones resulting in a decrease of bone mineral density. The available data suggest that proton pump inhibitors should be used with caution in patients with increased risk of osteoporosis.
