Arena Tablet 20 mg contains Vonoprazan 20 mg, a potent acid-suppressing medication used for the treatment of gastrointestinal disorders related to excessive stomach acid. Vonoprazan belongs to the potassium-competitive acid blocker (P-CAB) class, which offers rapid and long-lasting suppression of gastric acid secretion.

Arena 20 mg is primarily prescribed for conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and Helicobacter pylori-associated ulcers. Unlike traditional proton pump inhibitors (PPIs), Vonoprazan provides faster onset of action and more consistent acid suppression, making it an effective option for patients requiring reliable gastric acid control.

Composition

• Vonoprazan 20 mg

Mechanism of Action

Vonoprazan is a potassium-competitive acid blocker (P-CAB). Its mechanism of action includes:

By targeting the proton pump directly, Vonoprazan ensures fast and potent acid control, improving symptom relief and mucosal healing.
