Background: The use of proton-pump inhibitors (PPIs) has increased over the last decade. The objective of this study was to provide detailed utilization data on PPI use over time, with special emphasis on duration of PPI use and concomitant use of ulcerogenic drugs. Methods: Using the nationwide Danish Prescription Registry, we identified all Danish adults filling a PPI between 2002 and 2014. Using descriptive statistics, we reported (i) the distribution of use between single PPI entities, (ii) the development in incidence and prevalence of use over time, (iii) measures of duration and intensity of treatment, and (iv) the prevalence of use of ulcerogenic drugs among users of PPIs. Results: We identified 1,617,614 adults using PPIs during the study period. The prevalence of PPI use increased fourfold during the study period to 7.4% of all Danish adults in 2014. PPI use showed strong age dependency, reaching more than 20% among those aged at least 80 years. The proportion of users maintaining treatment over time increased with increasing age, with less than10% of those aged 18-39 years using PPIs 2 years after their first prescription, compared with about 40% among those aged at least 80 years. The overall use of ulcerogenic drugs among PPI users increased moderately, from 35% of users of PPI in 2002 to 45% in 2014. Conclusions:The use of PPIs is extensive and increasing rapidly, especially among the elderly.

In patients with residual reflux symptoms despite PPI treatment, adding an alginate offers additional decrease in the burden of reflux symptoms (EudraCT/IND Number: 2011-005486-21).

Gastric acid rebound hypersecretion following PPI therapy induces reflux-like symptoms post-treatment in asymptomatic volunteers, but the significance of this in patient populations is not clear. The studies in patients with reflux disease found no evidence of symptomatic RAHS, but these studies were hampered by severe methodological weaknesses.

ObjectiveAntireflux surgery (ARS) has been suggested as an alternative to lifelong use of proton pump inhibitors (PPI) in reflux disease. Data from clinical trials on PPI use after ARS have been conflicting. We investigated PPI use after ARS in the general Danish population using nationwide healthcare registries.DesignA nationwide retrospective follow-up study of all patients aged ≥18 and undergoing first-time ARS in Denmark during 1996–2010. Two outcome measures were used: redemption of first PPI prescription after ARS (index prescription) and a marker of long-term use, defined by an average PPI use of ≥180 defined daily doses (DDDs) per year. Kaplan–Meier curves and Cox proportional hazards model were used for statistics.Results3465 patients entered the analysis. 12.7% used no PPI in the year before surgery, while 14.2%, 13.4% and 59.7% used 1–89 DDD, 90–179 DDD and ≥180 DDD, respectively. Five-, 10- and 15-year risks of redeeming index PPI prescription were 57.5%, 72.4% and 82.6%, respectively. Similarly, 5-, 10- and 15-year risks of taking up long-term PPI use were 29.4%, 41.1% and 56.6%. Female gender, high age, ARS performed in most recent years, previous use of PPI and use of nonsteroidal anti-inflammatory drugs or antiplatelet therapy significantly increased the risk of PPI use.ConclusionsRisk of PPI use after ARS was higher than previously reported, and more than 50% of patients became long-term PPI users 10–15 years postsurgery. Patients should be made aware that long-term PPI therapy is often necessary after ARS.

Objectives: Proton pump inhibitors (PPI) are among the most frequently used drugs in the developed countries. In recent years, their use among children and adolescents has been on the increase. Guidelines recommend use for a period no longer than 4-8 weeks. The aim of this study was to describe time trends in prescribing patterns of PPI use among children, with emphasis on persistence to therapy. Methods: We used the Danish nationwide healthcare registries and identified all Danish children (0-17 years old) who were provided with a filled in PPI prescription between 2000 and 2015. Based on descriptive analyses, we reported trends over time in annual use, prevalent and incident users. Moreover, we evaluated persistence to treatment and doses used over time. Analyses were stratified by age groups (0-4, 5-11 and 12-17 years). Results: We identified 212 056 filled in PPI prescriptions prescribed to 78 489
