Kort om studiet
Prospektiv kohorteundersøgelse af 79.899 postmenopausale sygeplejersker i alderen 30-55 år, som i gennemsnit er fulgt i godt 7 år (1).

Den absolutte risiko for hoftefraktur var 2,02 tilfælde per 1.000 personnår (149 tilfælde/5.341 personer) i gruppen, der regelmæssigt havde taget protonpumpehæmmere (PPI) sammenlignet med 1,51 tilfælde per 1.000 personår (744 tilfælde/75.558 personer) hos dem, der ikke havde taget PPI.
Aldersjusteret hazard ratio (HR) var 1,35 (95 % sikkerhedsgrænser (CI) var 1,31 til 1,62).

Langvarig brug af PPI og rygning var associeret med øget risiko.

Blandt nuværende og tidligere rygere var brug af PPI associeret med mere end 50 % øget risiko for fraktur, HR 1,51 (CI 1,20 til 1,91).

Blandt kvinder, der aldrig havde røget var der ingen signifikant association, HR 1,06 (CI 0,77 til 1,46). (...)

ISSUE: FDA notified the public that the use of stomach acid drugs known as proton pump inhibitors (PPIs) may be associated with an increased risk of Clostridium difficile–associated diarrhea (CDAD). A diagnosis of CDAD should be considered for patients taking PPIs who develop diarrhea that does not improve. The FDA is working with manufacturers to include information about the increased risk of CDAD with use of PPIs in the drug labels.

FDA is also reviewing the risk of CDAD in users of histamine H2 receptor blockers. H2 receptor blockers are used to treat conditions such as gastroesophageal reflux disease (GERD), stomach and small intestine ulcers, and heartburn. (...)

PPIs raise fracture risk by 35%
pulsetoday.co.uk 1.2.2012
Regular use of proton pump inhibitors is associated with an increased hip fracture risk - particularly in smokers - concludes a large US study.

The prospective cohort study looked at data from 79,899 postmenopausal women on their use of PPIs between 2000 and 2008, and found those who regularly used PPIs for at least two years the risk was 35% higher than non-users, even when adjusted for age.

The absolute risk of hip fracture was 2.02 events per 1000 person years in regular PPI users, compared with 1.51 events in non-users. PPI use in current or former smokers was associated with a 51% increase in fracture risk, while there was no association between PPI use and fracture risk in women who had never smoked. (...)

Proton Pump Inhibitors Raise Hip Fracture Risk Over Time
medscape.com 31.1.2012
January 31, 2012 — A new study strengthens the association of long-term use of proton pump inhibitors (PPIs) with increased risk for hip fracture in postmenopausal women, particularly those who smoke.

PPIs can affect fracture risk by increasing secretion of gastrin, inhibiting calcium absorption, and altering osteoclast function. Use of these drugs to treat indigestion increased when they became available over the counter in the United States in 2003. In May 2010, the US Food and Drug Administration issued a warning about the possible link between extended PPI use and hip fracture and requested further information. (...)

Use of proton pump inhibitors and risk of hip fracture in relation to dietary and lifestyle factors: a prospective cohort study
BMJ 2012;344:e372 (31 January)
Objective To examine the association between chronic use of proton pump inhibitors (PPIs) and risk of hip fracture. (...)

Results During 565 786 person years of follow-up, we documented 893 incident hip fractures. The absolute risk of hip fracture among regular users of PPIs was 2.02 events per 1000 person years, compared with 1.51 events per 1000 person years among non-users. Compared with non-users, the risk of hip fracture among women who regularly used PPIs for at least two years was 35% higher (age adjusted hazard ratio 1.35 (95% confidence interval 1.13 to 1.62)), with longer use associated with increasing risk (Ptrend<0.01). Adjustment for risk factors, including body mass index, physical activity, and intake of calcium did not materially alter this association (hazard ratio 1.36 (1.13 to 1.63)). These associations were also not changed after accounting for reasons for PPI use. The relation between PPI use and fracture differed by smoking history (Pinteraction=0.03). Among current and former smokers, PPI use was associated with greater than 50% increase in risk of fracture, with a multivariate hazard ratio for fracture of 1.51 (1.20 to 1.91). In contrast, among women who never smoked there was no association (multivariate hazard ratio 1.06 (0.77 to 1.46)). In a meta-analysis of these results with 10 prior studies, the pooled odds ratio of hip fracture associated with PPI use was 1.30 (1.25 to 1.36).

Conclusion Chronic use of PPIs is associated with increased risk of hip fracture, particularly among women with a history of smoking. (...)

BACKGROUND: Concerns have been raised about the risk of fractures with acid-suppressive medications, such as proton pump inhibitors and histamine(2)-receptor antagonists. (...)

CONCLUSION: In this meta-analysis of observational studies, proton pump inhibitors modestly increased the risk of hip, spine, and any-site fractures, whereas histamine(2)-receptor antagonists were not associated with fracture risk. The possibility of residual confounding cannot be excluded. Further skeletal evaluation should be considered for patients who are taking proton pump inhibitors and also at risk for osteoporotic fracture. (...)

Study questions heartburn drugs for kids
reuters.com 5.4.2011
NEW YORK (Reuters Health) - Acid-suppressing drugs like Prilosec and Prevacid may not be much help for infants with troublesome acid reflux, and there's too little evidence that they help older children and teenagers, a new research review concludes.

The findings, reported in the journal Pediatrics, question the usefulness of so-called proton-pump inhibitors in children with gastroesophageal reflux disease, or GERD.
The drugs, which suppress stomach-acid production, have names like omeprazole (Prilosec), lansoprazole (Prevacid) and esomeprazole (Nexium). Prilosec and Prevacid are both available over the counter, and typically cost about 50 cents per pill. Nexium is still only available by prescription, and is more expensive.

In the new study, the researchers reviewed 12 clinical trials that tested the medications for treating GERD in infants, children or teenagers.
They found no good evidence that the drugs eased acid-reflux symptoms in infants -- such as crying and "fussing" after being fed. (...)

Proton Pump Inhibitor drugs (PPIs): Drug Safety Communication - Low Magnesium Levels Can Be Associated With Long-Term Use
fda.gov 2.3.2011
Prescription PPIs include Nexium (esomeprazole magnesium), Dexilant (dexlansoprazole), Prilosec (omeprazole), Zegerid (omeprazole and sodium bicarbonate), Prevacid (lansoprazole), Protonix (pantoprazole sodium), AcipHex (rabeprazole sodium), and Vimovo (a prescription combination drug product that contains a PPI (esomeprazole magnesium and naproxen).

Over-the-counter (OTC) PPIs include Prilosec OTC (omeprazole), Zegerid OTC (omeprazole and sodium bicarbonate), and Prevacid 24HR (lansoprazole). (...)

ISSUE: FDA notified healthcare professionals and the public that prescription proton pump inhibitor (PPI) drugs may cause low serum magnesium levels (hypomagnesemia) if taken for prolonged periods of time (in most cases, longer than one year). Low serum magnesium levels can result in serious adverse events including muscle spasm (tetany), irregular heartbeat (arrhythmias), and convulsions (seizures); however, patients do not always have these symptoms. Treatment of hypomagnesemia generally requires magnesium supplements. In approximately one-quarter of the cases reviewed, magnesium supplementation alone did not improve low serum magnesium levels and the PPI had to be discontinued.

BACKGROUND: PPIs work by reducing the amount of acid in the stomach and are used to treat conditions such as gastroesophageal reflux disease (GERD), stomach and small intestine ulcers, and inflammation of the esophagus. (...)

Proton Pump Inhibitors (PPIs)
fda.gov 9.8.2010
The FDA is revising the prescription and over-the-counter (OTC) labels for proton pump inhibitors to include new safety information about a possible increased risk of fractures of the hip, wrist, and spine with the use of these medications.

The new safety information is based on FDA's review of several epidemiological studies. Some studies found that those at greatest risk for these fractures received high doses of proton pump inhibitors or used them for one year or more. The majority of the studies evaluated individuals 50 years of age or older and the increased risk of fracture primarily was observed in this age group. As a precaution, the "Drug Facts" label on the OTC proton pump inhibitors (indicated for 14 days of continuous use) also is being revised to include information about this risk. (...)

Jeg leste med undring Hatlebakk og medarbeideres emosjonelle kommentar i Tidsskriftet nr. 6/10 (1) til mitt innlegg om protonpumpehemmere solgt uten resept (2). Det kan synes som om de overhodet ikke kjenner til den danske studien som viste at friske, symptomfrie medisinstudenter får dyspepsi etter bruk av protonpumpehemmere (3) på grunn av økt syresekresjon (4). Allikevel hevder de at den kliniske betydning av tilbakefall med hypersekresjon av syre (acid rebound) ikke er vist (1). Hvorfor skulle ikke den økte syresekresjonen forverre reflukssykdommen der det på forhånd er en funksjonell defekt i ventilfunksjonen i cardia når den gir reflukssymptomer hos friske? Er ikke tilbakefall med hypersekresjon av syre den mest sannsynlige årsaken til den påfallende økningen i reflukssykdom man har sett de siste tiåene? (...)

Overuse of heartburn drugs is risky: study (Overforbruk av legemidler mot halsbrann er risikabelt ifølge studie)
reuters.com 10.5.2010
(Reuters) - Although they are sometimes used to make spicy meals go down easier, common heartburn drugs can cause serious side effects and should be used with caution, a series of studies released on Monday suggests.

Well-known brands of the drugs -- called proton pump inhibitors or PPIs -- include AstraZeneca's Nexium and Prilosec. Formerly AstraZeneca's biggest seller, Prilosec is available generically as omeprazole and is also sold over the counter by Procter & Gamble Co.

While the drugs are a great help to the right patients, they can raise the risk of fractures in post-menopausal women and cause bacterial infections in many patients, according to a special report in the Archives of Internal Medicine. (...)

How Safe Are Popular Reflux Drugs? (Hvor sikre er populære legemidler mot reflukssykdom?)
medicinenet.com 4.11.2009
(HealthDay News) -- Millions of Americans take drugs like Nexium, Prevacid and Prilosec to ease the erosive effects of acid reflux, but do these medicines put patients at risk for other health problems?

Experts remain divided on the potential dangers these common prescription medications might pose.

The drugs belong to a class of pharmaceuticals called "proton pump inhibitors," or PPIs, which are generally considered safe and effective. But lately these acid-reducing medications have been the subject of studies linking their use to a number of health risks, from an increased rate of hip fracture to a greater likelihood of diarrhea and community-acquired pneumonia.

FDA safety review on Nexium and Prilosec hits AstraZeneca stock
pharmatimes.com 10.8.2007
AstraZeneca shares have taken a tumble after health regulators in the USA and in Canada revealed that they are conducting safety reviews of the blockbuster antiulcerants Nexium and Prilosec, even though findings thus far suggest that the drugs do not increase the risk of heart trouble.

The process began at the end of May when AstraZeneca sent the US Food and Drug Administration, and other regulatory authorities worldwide, a preliminary review of new data from two small long-term clinical studies of Nexium (esomeprazole) and Prilosec (omeprazole) in patients with severe gastroesophageal reflux disease (GERD). Patients were randomised to receive either drug or to have surgery to control their GERD and the results from the 14-year study of Prilosec and five-year analyses from an ongoing study of Nexium “raised concerns that long-term use” of both drugs “may have increased the risk of heart attacks, heart failure, and heart-related sudden death...compared to patients who received surgery”, the FDA stated.

Study Links Heartburn Drugs, Broken Hip
forbes.com 26.12.2006
Taking such popular heartburn drugs as Nexium, Prevacid or Prilosec for a year or more can raise the risk of a broken hip markedly in people over 50, a large study in Britain found.

The study raises questions about the safety of some of the most widely used and heavily promoted prescription drugs on the market, taken by millions of people.

The researchers speculated that when the drugs reduce acid in the stomach, they also make it more difficult for the body to absorb bone-building calcium. That can lead to weaker bones and fractures.

Hip fractures in the elderly often lead to life-threatening complications. As a result, doctors should make sure patients have good reason to stay on heartburn drugs long term, said study co-author Dr. Yu-Xiao Yang of the University of Pennsylvania School of Medicine.

"The general perception is they are relatively harmless," Yang said. "They often are used without a clear or justified indication for the treatment." (...)

Heart-burn cure may be worse than cause
seattletimes.nwsource.com 20.12.2005
CHICAGO — Holiday revelers beware: Seasonal indulgences such as eggnog and fruitcake might give you heartburn, but the acid-fighting medicine you take for relief might lead to something worse, researchers say.

People on popular prescription drugs for treating acid reflux — Prilosec, Prevacid and Nexium — seem more prone to getting a potentially dangerous diarrhea caused by the bacterium Clostridium difficile, new research shows. C-diff, as it's known, can cause severe diarrhea and crampy intestinal inflammation called colitis.

Dr. Sandra Dial and colleagues at McGill University in Montreal examined data on more than 18,000 patients in the United Kingdom from 1994 to 2004. During that time, 1,672 cases of C-diff were diagnosed, and the numbers increased from less than 1 per 100,000 in 1994 to 22 per 100,000 last year.

Patients with prescriptions for powerful acid fighters called proton pump inhibitors, which include Prilosec and Prevacid, were almost three times more likely to be diagnosed with the bug than those not taking the drugs.

Those on less potent prescription drugs called H2 receptor antagonists, which include Pepcid and Zantac, were two times more likely than nonusers to get C-diff infections.

The widely used and heavily promoted drugs reduce levels of gastric acid that can keep C-diff at bay. (...)
