Esophageal ulcers associated with tetracycline therapy
JAMA
|June 21, 1976
Summary
Tetracycline and doxycycline can cause esophageal ulcers, especially in patients with swallowing difficulties. Take these medications with plenty of water and avoid lying down soon after.
Area of Science:
- Gastroenterology
- Pharmacology
Background:
- Esophageal ulceration is an uncommon adverse effect of medications.
- Tetracycline and doxycycline are commonly prescribed antibiotics.
Observation:
- Three patients developed esophageal ulcers after ingesting tetracycline or doxycycline capsules.
- A clear temporal link was observed between medication intake and ulcer onset.
Findings:
- The study suggests a causal relationship between tetracycline/doxycycline ingestion and esophageal ulceration.
- Esophageal obstructive elements may increase the risk of developing these ulcers.
Implications:
- Consider alternative antibiotics for patients with esophageal obstructions.
- Advise patients to take tetracycline/doxycycline with water and avoid recumbency for at least one hour after ingestion to prevent esophageal injury.

01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:16Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy
Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...
01:23Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:26Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
