Abstract

Background:

Guideline and reimbursement modifications have been introduced to optimize prescribing of antisecretory medication in Danish general practice. Impacts of the interventions have not been evaluated.

Objectives:

To analyse developments in prescribing of antisecretory medication in Denmark 2001-2011 and to assess the impacts of interventions on prescribing of antisecretory medication.

Methods:

Register-based cohort study covering the entire Danish population of currently 5.5 million inhabitants. Developments in the prescribing of antisecretory medication over time in Denmark between 2001 and 2011 and association with age and gender of users along with the impact of interventions on the prescribing of drug subgroups are analysed.

Results:

96.8% of all antisecretory drugs sold are proton pump inhibitors (PPIs) and 94.4% of the PPIs are prescribed in primary care. Prescribing of PPIs has increased substantially during the past decade. Both number of users and the average individual use have increased. The prescribing of ulcerogenic drugs to the elderly has stagnated in the same time range. Reimbursement modifications and scientific guidelines do not seem to have had a substantial influence on the steadily increasing prescribing of PPIs.

Conclusion:

Use of PPIs has increased substantially during the past decade, without a change in indications for use of PPIs in the same time range. Interventions to enhance adherence to guidelines and promote rational use of PPIs do not seem to have had a substantial influence on the overall prescribing rate.

Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors

Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors

Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.
Gastric acid, a potent cocktail of hydrogen and chloride ions, is produced in specialized parietal cells within the...

Peptic Ulcer Disease IV: Management

Medical treatment strategies for peptic ulcers encompass various methods. The primary goal of treatment is to diminish gastric acidity and strengthen mucosal defense mechanisms.
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.
Pharmacological management
The prevailing therapy for peptic ulcers involves a combination of managing the patient's current...

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists

Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...

Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids

Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids

In the complex environment of the gastric lumen, excessive acid secretion can lead to the formation or worsening of ulcers within the delicate mucosal layer. Antacids, such as sodium bicarbonate and calcium carbonate, provide relief by neutralizing this acid, transforming it into harmless salt and water. This neutralization process raises the gastric pH from a highly acidic level of 1 to a more basic 3-4, reducing the acidity within the stomach.
However, this neutralization reaction between...

Peptic Ulcer Disease I: Introduction

Peptic Ulcer Disease I: Introduction

Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Peptic Ulcer Disease I: Introduction

Peptic Ulcer Disease I: Introduction

Peptic ulcer disease (PUD) involves breaks in the gastrointestinal tract's mucosal lining, primarily in the stomach and duodenum, with less frequent occurrences in the lower esophagus or near the pylorus.Ulcers can be acute or chronic. Acute ulcers are short-lived with minimal inflammation and heal quickly after the irritant is removed. Chronic ulcers persist, may recur, and often cause scarring due to ongoing tissue damage. Superficial erosions affect only the mucosal layer and are called...
