Is there an association between Omeprazole (a Proton Pump Inhibitor) and the development of osteoporosis?

From the Guidelines

Long-term use of omeprazole may increase the risk of osteoporosis, and patients should consider preventive measures such as calcium and vitamin D supplementation, as well as regular bone density screening. When considering the use of omeprazole, it is essential to weigh the benefits against the potential risks, including osteoporosis, as noted in the British Society of Gastroenterology guidelines on the diagnosis and management of Barrett's oesophagus 1. The guidelines mention that long-term side effects of acid suppression drugs, including osteoporosis, need to be taken into account.

Key considerations for patients taking omeprazole include:

• Using the lowest effective dose, typically 20 mg daily, to minimize the risk of osteoporosis
• Calcium supplementation (1000-1200 mg daily) and vitamin D supplementation (800-1000 IU daily) to support bone health
• Regular bone density screening to monitor for potential bone mineral density loss
• Periodic attempts to reduce or discontinue omeprazole under medical supervision for patients requiring long-term acid suppression
• Maintaining a healthy lifestyle, including regular weight-bearing exercise, and avoiding smoking and excessive alcohol consumption to support overall bone health.

The benefits of omeprazole for symptom control in patients with reflux disease are well-established, with a Cochrane review finding that PPIs are more effective than H2 RA for symptom control 1. However, the potential risks, including osteoporosis, must be carefully considered and managed to minimize harm and optimize patient outcomes.

From the FDA Drug Label

5.4 Bone Fracture Several published observational studies suggest that proton pump inhibitor (PPI) therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine. The risk of fracture was increased in patients who received high-dose, defined as multiple daily doses, and long-term PPI therapy (a year or longer) Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Patients at risk for osteoporosis-related fractures should be managed according to established treatment guidelines [see Dosage and Administration (2.1), Adverse Reactions (6.3)].

• Osteoporosis-related fractures: Omeprazole may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine, particularly with high-dose and long-term therapy.
• Risk factors: Patients who receive multiple daily doses and long-term PPI therapy (a year or longer) are at increased risk of fracture.
• Prevention: Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated, and those at risk for osteoporosis-related fractures should be managed according to established treatment guidelines 2.

From the Research

Omeprazole and Osteoporosis

• There is no direct evidence in the provided studies that links omeprazole to osteoporosis 3, 4, 5, 6, 7.
• The studies primarily focus on the treatment of osteoporosis, the efficacy and safety of omeprazole in patients with Zollinger-Ellison syndrome, and the long-term use of omeprazole in resistant gastroesophageal reflux disease.
• Osteoporosis studies suggest that antiresorptive drugs such as bisphosphonates and denosumab are first-line treatment options, and that calcium and vitamin D supplementation may benefit people with a high risk of deficiency 3, 4.
• The provided studies on omeprazole discuss its efficacy and safety in various conditions, but do not mention its relationship to osteoporosis 5, 6, 7.
