|Proton Pump Inhibitors: Dependency and Risk|
|By Jeffrey E. Keller MD|
I recently saw yet another patient come into the jail who was worried about one particular drug in a long list of medications he was taking—his Nexium. “I can’t miss a day of taking Nexium” he said, “It has to be refilled right away!” He was more concerned about Nexium than his blood pressure meds, his diabetes medications or his mental health medications. There was a lot of Nexium-anxiety on display.
And the funny thing is, this happens all the time! I have seen lots of jail patients wedded to their proton pump inhibitor, whether Nexium, Prilosec, Protonix or what ever. A prescription of a PPI often becomes a lifelong need.
I think it is important for all prescribers to understand why this is so. And why, despite this, it is not a good idea for most people to be on PPIs for long periods of time. Prescribers tend to under-estimate both the potential harms of long-term PPI use and the potential for patients to become dependent on them.
To this end, today’s Jail Medicine post presents two “Must Know” papers about Proton Pump Inhibitors.
What I call the first paper is actually two: but both studies that had the same design and same results. This study (done twice) is one of my all-time favorite medical studies:
After eight weeks of having these patients take the PPI, you abruptly stop it. And here is the interesting thing that happens when you do this: 50% of these patients will develop significant acid reflux symptoms! This phenomenon is thought to be caused by a rebound acid hypersecretion caused by elevated levels of the hormone Gastrin.
This study shows why many patients have problems stopping a PPI. They get serious heartburn every time they try. But look what else has happened here: healthy, asymptomatic people were given a disease in this study. Remember that these patients had no problem at the beginning of the study and at the end, half of them now had GERD. And because it is hard to stop the PPI, these patients may be troubled by GERD for the rest of their lives.
The second article on PPIs comes from one of my all-time favorite education sites: The Oregon State Drug Review. This is a collection of drug review, evaluations and editorials done by the Oregon State College of Pharmacy. These are all great and highly recommended. But this one is a true gem:
Here are some of the major teaching points and recommendations:
The H2 blocker antacids like ranitidine seem to be much safer and do not exhibit the rebound GERD phenomenon that PPIs have. We should actually be prescribing prn ranitidine more and PPIs less.
Read this paper! Twice! It’s short and worth it.
