Azeloprazole

Azeloprazole is a proton pump inhibitor (PPI) used in the treatment of various gastrointestinal conditions. It works by reducing the amount of stomach acid produced by the gastric glands in the stomach lining.

Mechanism of Action

Azeloprazole inhibits the H+/K+ ATPase enzyme system, also known as the proton pump, in the parietal cells of the stomach. This inhibition prevents the final step in the production of gastric acid, thereby reducing acidity in the stomach.

Indications

Azeloprazole is indicated for the treatment of:

• Gastroesophageal reflux disease (GERD)
• Peptic ulcer disease
• Zollinger-Ellison syndrome
• Erosive esophagitis

Pharmacokinetics

Azeloprazole is absorbed in the small intestine and undergoes extensive first-pass metabolism in the liver. It is primarily excreted through the urine and feces.

Side Effects

Common side effects of azeloprazole include:

• Headache
• Nausea
• Diarrhea
• Abdominal pain

Serious side effects may include:

• Clostridium difficile infection
• Osteoporosis-related fractures
• Hypomagnesemia

Contraindications

Azeloprazole is contraindicated in patients with known hypersensitivity to any component of the formulation or to other PPIs.

Drug Interactions

Azeloprazole may interact with:

• Warfarin
• Clopidogrel
• Methotrexate
• Ketoconazole

Dosage and Administration

Azeloprazole is typically administered orally, with the dosage and duration of treatment depending on the specific condition being treated.
