Summary
Oral doxycycline taken at bedtime with minimal water can cause esophageal ulcerations. Symptoms often resolve quickly with treatment, even if doxycycline continues.
Area of Science:
- Gastroenterology
- Pharmacology
Background:
- Drug-induced esophageal injury is a recognized clinical issue.
- Doxycycline is a common antibiotic with potential gastrointestinal side effects.
Purpose of the Study:
- To investigate the role of oral doxycycline in causing esophageal ulcerations.
- To identify risk factors associated with doxycycline-induced esophageal injury.
Main Methods:
- Retrospective analysis of 16 patients presenting with drug-induced esophageal ulcerations.
- Clinical data including symptoms, timing of drug intake, and endoscopic findings were reviewed.
Main Results:
- 13 patients with doxycycline-induced esophageal ulcerations were analyzed.
- Common symptoms included odynophagia, retrosternal pain, and dysphagia.
- Ulcers were located in the mid-esophagus; symptoms resolved within a week of treatment.
Conclusions:
- Oral doxycycline intake, particularly at bedtime with insufficient water, is a significant cause of esophageal ulcerations.
- Antireflux treatment is effective, and doxycycline can often be continued safely.

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 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...
Esophageal Strictures-I: Introduction
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Peptic Ulcer Disease II: Pathophysiology
Peptic ulcer disease develops when protective mechanisms of the gastrointestinal mucosa are overwhelmed by harmful factors, leading to localized erosions in the stomach or proximal duodenum. The main causes are Helicobacter pylori infection and chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs).Helicobacter pylori–Induced InjuryBacterial Adaptation and Colonization:H. pylori is a spiral, Gram-negative bacterium adapted to the acidic stomach. and transmitted through oral-oral or...
Peptic Ulcer Disease II: Pathophysiology
Peptic Ulcer Disease (PUD) is characterized by the development of ulcers in the stomach or duodenal mucosa. Its pathophysiology is complex, involving a balance between damaging and protective elements.
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
