Many patients will be able to manage symptoms during this withdrawal period with alternative medicines, such as antacids. There is also a Peer Group Discussion on this article. The treatment of symptoms caused by gastric acid dates backs to the ancient Greeks, who used coral powder calcium carbonate to alleviate dyspepsia.

This was followed by the introduction of proton pump inhibitors PPIs , which were even more effective in reducing gastric acid production. PPIs have now largely superseded H2-receptor antagonists, resulting in an improved quality of life for many patients.

Their effectiveness, however, has also led to PPIs being used more widely in primary care than almost any other medicine. In , there were dispensed prescriptions for omeprazole for every registered patients, making it the third most widely prescribed medicine in New Zealand.

In New Zealand there are three fully subsidised PPIs available on the Pharmaceutical Schedule: omeprazole, lansoprazole and pantoprazole.

Rabeprazole is available unsubsidised, with a prescription. Patients should be asked about any use of non-prescription medicines before acid suppressive medicines are prescribed.

Refer to the New Zealand Formulary for further details on these medicines: www. Figure 1: The number of patients who were dispensed omeprazole, pantoprazole or lansoprazole from a community pharmacy in New Zealand — It also allows for choices in formulation, e. When initiating PPI treatment it is helpful to discuss with patients what the expected duration of treatment is likely to be.

This reinforces the message that treatment will not continue indefinitely, unless the indication remains, and is likely to make later discussions about dose adjustment and treatment withdrawal easier. For most patients an appropriate starting regimen is omeprazole 20 mg, once daily depending on the indication.

Over time, and again depending on the indication for treatment, the dose of PPI may be able to be reduced, e. PPIs are prodrugs, i. Once they have passed through the stomach and the enteric coating has dissolved in the small intestine, PPIs are absorbed into the blood where they have a relatively short plasma half-life of 1 — 1. This prevents the transport of acidic hydrogen ions into the gut lumen for 10 — 14 hours.

Gastrin is the hormone that stimulates parietal cells to release gastric acid. When PPI inhibition of gastric acid production occurs, gastrin release is increased to compensate for the decreased acidity of the stomach. Recently, several studies have suggested that when PPIs are withdrawn the body will continue to produce gastrin at above pre-treatment levels, causing an effect referred to as rebound acid secretion.

Proton pump inhibitors are indicated in the treatment of suspected or confirmed GORD. The treatment regimen depends on the severity of symptoms and the likelihood of the patient developing complications.

PPIs can be used to: 1, 8. When managing patients with mild GORD, it is important that the patient and clinician both agree that the regimen will be regularly reviewed, with the goal of treatment being lifestyle control of symptoms with minimal reliance on medicines.

The lowest effective dose of PPI should be used for the shortest possible time. Risk factors for gastrointestinal adverse effects, e. Patients should be advised to report any gastrointestinal symptoms e. For ulcer prevention, the recommended regimen is omeprazole 20 mg, once daily, for the duration of NSAID treatment. Proton pump inhibitors are recommended for the eradication of H.

For example, a seven day course of: 4. Other regimens using different dosing intervals or other PPIs, e. Confirmation of eradication of H. A test of cure may be considered in patients with a recurrence of symptoms, a peptic ulcer complication or those with important co-morbidities.

In other patients, e. However, in each practice population there will be some patients for whom it is appropriate to reduce the dose of the PPI they are prescribed, e. For patients taking PPIs long-term the need for ongoing treatment should be reassessed at every consultation.

There is no clear evidence as to what the best regimen for withdrawing PPI treatment is, but in general, downward dose titration should be considered when symptoms are under control. The patient responds to treatment and their symptoms resolve. The dose is then reduced to 10 mg, daily, for two weeks, and then treatment is stopped. This should return to normal within two weeks. The symptoms caused by rebound acid secretion, e. The possibility of rebound acid secretion should be discussed with patients so they can be prepared for this when withdrawing from PPI treatment.

Medicines that contain both an antacid and an anti-foaming agent, e. Mylanta P oral liquid, Acidex oral liquid, Gaviscon Double Strength tablets are likely to be the most effective treatment for rebound acid secretion. Aluminium hydroxide tablets can also be effective. The rate of adverse effects associated with PPI treatment is relatively low.

However, given that each practice is likely to have many patients taking PPIs, clinicians need to be aware of the potential risks. These risks should be discussed with patients, and the need for periodic monitoring considered in those at increased risk. All three subsidised PPIs available in New Zealand can cause headache and gastrointestinal adverse effects, e.

Less frequently, PPI use is associated with dry mouth, peripheral oedema, dizziness, sleep disturbances, fatigue, paraesthesia, arthalgia, myalgia, rash, pruritus and interstitial nephritis. PPIs are not known to be associated with an increased risk of foetal malformations in humans Pregnancy Risk Category B3.

A reasonable approach for pregnant women who require acid suppressive medication is to trial antacids e. Higher doses of PPIs should be avoided in patients with moderate to severe liver disease because decreased metabolism may cause the medicine to accumulate see NZF for details. Gastric acid suppression with PPIs increases the risk of infection with gastrointestinal or respiratory pathogens, although the absolute risk to most patients remains low.
