Vonoprazan 20mg Uses

Vonoprazan 20mg is prescribed for:

• Gastroesophageal reflux disease (GERD) – Helps reduce heartburn, acid reflux, and esophageal irritation.
• Peptic ulcer disease (PUD) – Treats stomach and duodenal ulcers caused by excess acid production.
• H. pylori eradication therapy – Used in combination with antibiotics to eliminate H. pylori infections.

How Does Vonoprazan 20mg Work?

Vonoprazan is a potassium-competitive acid blocker (P-CAB) that works differently from PPIs.

• Rapid Acid Suppression – Blocks the acid-producing enzyme (H⁺/K⁺-ATPase) in the stomach.
• Long-Lasting Effect – Provides sustained acid suppression for 24 hours with a single dose.
• Immediate Activation – Works faster than PPIs, providing quicker relief from acid-related symptoms.
• Stable Efficacy – Less affected by food intake and genetic variations, ensuring consistent acid suppression.
