Acid reflux drug linked to more than doubled risk of stomach cancer study

Acid reflux drug linked to more than doubled risk of stomach cancer – study

Press Association

Tuesday 31 October 2017 23.30 GMT

A drug commonly used to treat acid reflux is linked to a more than doubled risk of developing stomach cancer, researchers have claimed. Proton pump inhibitors (PPIs) reduce the amount of acid made by the stomach and are used to treat acid reflux and stomach ulcers.

A study published in the journal Gut identified an association between long-term use of the drug and a 2.4 times higher risk of developing stomach cancer. In the UK, there are more than 50m prescriptions for PPIs every year but they have been linked to side-effects and an increased risk of death.

A link between PPIs and a higher stomach cancer risk has previously been identified by academics – but never in a study that first eliminates a bacteria suspected of fuelling the illness’s development. Research by the University of Hong Kong and University College London found that after the Helicobacter pylori was removed, the risk of developing the disease still rose in line with the dose and duration of PPI treatment.

They compared the use of PPI against another drug which limits acid production known as H2 blockers in 63,397 adults. The participants selected had been treated with triple therapy, which combines PPI and antibiotics to kill off the H pylori bacteria over a week, between 2003 and 2012. Scientists then monitored them until they either developed stomach cancer, died or reached the end of the study at the end of 2015.

During this period, 3,271 people took PPIs for an average of almost three years, while 21,729 participants took H2 blockers. A total of 153 people developed stomach cancer, none of whom tested positive for H plyori but all had long-standing problems with stomach inflammation, the study found.

While H2 blockers were found to have no link to a higher risk of stomach cancer, PPIs was found connected to an increased risk of more than double. Daily use of PPIs was associated with a risk of developing the illness that was more than four times higher (4.55) than those who used it weekly. Similarly, when the drug was used for more than a year, the risk of developing stomach cancer rose five-fold, and as high as eight-fold after three or more years, the findings showed.

1. PPIs should *never* have been made OTC.

They should be prescription only for limited-time use. There have been known side effects and risks with PPIs for quite some time.

Last spring, I went to the ER after two episodes of chest pain, thinking it could be of coronary origin because of my age and family history. It turned out to be nothing but heartburn and the doctor prescribed a PPI. I already take an H2 blocker (ranitidine) for GERD and when I told her I'd rather increase the dose of that because I didn't want to take a PPI, she looked very surprised at first. Then she nodded and told me how much to increase the ranitidine.

The H2 blocker works just fine, with no side effects or long-term risks. (It also never hurts to have a bottle of Pepto-Bismol, Maalox, or another old-time antacid on hand "just in case." ) I get angry every time I see an ad for an over-the-counter PPI pushed on people like it's no big deal. It is a big deal.

6. H2 blockers such as Zantac have a good safety profile, though they can affect the metabolism of some

drugs, and falsely interfere with the interpretation of some chemistries in the lab such as serum creatinine, for the most part they are fairly safe.

The H2 blockers can also be used to treat hives, but should be done with knowledge of a physician because knowing the cause of hives is quite important to prevent a potential future anaphylaxis reaction]

9. Good information to have!

It's always important to check drug interactions, for sure. I didn't know about using H2 blockers to treat hives, though. Very interesting.

Thanks!

2. This strikes me as a classic example of over-medication.

What exactly is wrong with ordinary anti-acids? Or simply tolerating the discomfort?

I know I cannot answer for anyone else, but sometimes putting up with a bit of discomfort may not be so awful.

So many drugs have such awful consequences or side effects, and those things aren't really explained to patients, except as sort of hand-waving asides. Sometimes the cure is worse than the disease.

3. Tolerating the impact of heartburn
Thu Nov 2, 2017, 05:19 AM

Particularly in those with persistent heartburn, can produce esophageal cancer, so it's not exactly something to recommend people do.

5. Medication sometimes needed but a lot of heartburn can be reduced by mechanical (physical) means
Thu Nov 2, 2017, 08:10 AM
Nov 2017

Such as not eating late night snacks, avoiding major alcohol consumption in late evening, sleeping on left side (at least initially), losing weight, eating larger breakfasts and smaller dinner portion sizes ....

Ideally, we wake up hungry in the morning, not still feeling sated from a large dinner the night before.

8. Yep. Sensible suggestions that too many people don't want to follow.

They want a magic pill instead.

I get my share of heartburn, and a couple of OTC anti-acid pills invariably do the trick for me. Perhaps I'm unusually lucky that they do, but I sometimes wonder if people try those things, along with what you've suggested, before going for the big pharmaceutical guns.

It also bothers me a lot that so many people are on so many different medications. I have a friend who is on about six or seven, and every few weeks he'll have a bout of feeling quite crappy, and I honestly think it's from the interaction of all those meds.

10. simply tolerating the discomfort?
Sun Nov 19, 2017, 05:17 PM

I take quite a few prescription meds. I sometimes get HORRIBLE GERD or heartburn or sometimes just reflux. In my case (as I'm sure with many) the cure is NOT worse than the disease.

Have you ever experienced excruciating pain that makes you wonder if you're having a heart attack, that causes you to wonder if your next breath might be your last?

I have numerous medical conditions that require medications that cause that burning pain that sometimes sets me on my knees.

No, I won't tolerate the "discomfort" for it's far more than just uncomfortable.

I do prefer the H2 route though as compared to PPIs

4. I was on several during trials and the max time of use then was 3 mos.

I overproduced acid and had a reflux problem. I finally got off them but use Pepcid when necessary maybe once or twice in a month. I love hot peppers. The biggest changes I made was to stop smoking. I use of 3-4 inch blocks under the headboard of my bed, it helps with what was called the "bad vapors" in the 18th century. The incline can be seen in many drawings and in 17th-18th military posts in how they constructed bunks. Simply sleeping on your left side also reduces reflux.

They weren't meant to be a permanent solution, at least that is what I was told. Prescriptions forms such as tagamet, have various side effects, many more than they list.

7. To put that in perspective, new stomach cancer cases run about 7/100,000, breast cancer about
Thu Nov 2, 2017, 08:23 AM

125/100,000, prostate cancer 120/100,000, all per year.

A doubling or 8-fold increase in the risk is quite significant, but still that isn't going to make me put up with pain that can be quite severe at times if it gets into your esophagus.

I should probably stop drinking coffee which is the main culprit, but that will actually increase the risk of certain cancers.
