Millions of people in the UK take drugs such as omeprazole, frequently on a continuous basis, and they are even available directly from pharmacies.Millions of people in the UK take drugs such as omeprazole, frequently on a continuous basis, and they are even available directly from pharmacies.
Physicians should be aware of this potential association when considering PPI therapy Researchers at University of Pennsylvania Medical School Some research has already suggested that taking the drugs could interfere with the body's ability to absorb calcium to keep bones strong.Physicians should be aware of this potential association when considering PPI therapy Researchers at University of Pennsylvania Medical School Some research has already suggested that taking the drugs could interfere with the body's ability to absorb calcium to keep bones strong.
The Jama study looked at a large group of records from the UK General Practice Research Database. All the people involved were aged over 50, and some had been taking proton pump inhibitors (PPI).The Jama study looked at a large group of records from the UK General Practice Research Database.

The researchers found that people who had been taking the drugs for more than a year - not an uncommon scenario - had a 44% greater risk of suffering a hip fracture.The researchers found that people who had been taking the drugs for more than a year - not an uncommon scenario - had a 44% greater risk of suffering a hip fracture.

Hip fracture is one of the most significant causes of severe disability in older people - up to one in five people who suffer a fracture following a fall die within 12 months.Hip fracture is one of the most significant causes of severe disability in older people - up to one in five people who suffer a fracture following a fall die within 12 months.
The costs to the NHS of hip fractures are also huge, not only immediately afterwards but in the cost of emergency hip replacement operations.The costs to the NHS of hip fractures are also huge, not only immediately afterwards but in the cost of emergency hip replacement operations.
The researchers said that while the link between increased risk and taking the medication appeared clear, it was possible that the type, general health and age of patients taking regular PPI medication might contribute to the difference in some way.The researchers said that while the link between increased risk and taking the medication appeared clear, it was possible that the type, general health and age of patients taking regular PPI medication might contribute to the difference in some way.

Since 2004, omeprazole has been available directly from UK chemists without prescription, although at a lower than the normal prescribed dose, and, accompanied by guidelines which recommend it only for short periods.Since 2004, omeprazole has been available directly from UK chemists without prescription, although at a lower than the normal prescribed dose, and, accompanied by guidelines which recommend it only for short periods.
