VPRAZ 20

# Vonoprazan 20 mg ## SHORT DESCRIPTION **Vonoprazan 20 mg** is an oral **potassium-competitive acid blocker (P-CAB)** used to reduce stomach acid production. It provides potent and sustained suppression of gastric acid and may be prescribed for conditions such as **acid reflux, erosive esophagitis, stomach and duodenal ulcers, and *Helicobacter pylori* (H. pylori) eradication therapy**, depending on the approved indication and local prescribing guidelines. Unlike traditional proton pump inhibitors (PPIs), vonoprazan blocks the gastric proton pump through a different mechanism and does not require activation in an acidic environment. ## KEY BENEFITS * Provides strong and sustained reduction of stomach acid * Helps relieve symptoms associated with acid reflux * Supports healing of acid-related damage to the esophagus * Helps promote healing of certain gastric and duodenal ulcers * Can be used as part of specific **H. pylori eradication regimens** * May provide rapid and consistent acid suppression * Helps maintain a less acidic environment in the stomach ## USES / INDICATIONS Vonoprazan 20 mg may be prescribed for: * **Erosive esophagitis** * Healing and maintenance of healing of acid-related esophageal damage * **Gastroesophageal reflux disease (GERD)**, depending on the approved indication * Gastric ulcers * Duodenal ulcers * Certain acid-related gastrointestinal disorders * **H. pylori eradication**, in combination with appropriate antibiotics and, where indicated, other medicines The exact approved uses vary by country and product. ## HOW IT WORKS Vonoprazan belongs to the **potassium-competitive acid blocker (P-CAB)** class. It directly and reversibly inhibits the **H⁺/K⁺-ATPase proton pump** in gastric parietal cells. This pump is responsible for the final step of stomach acid secretion. By blocking the proton pump, vonoprazan substantially reduces gastric acid production. **Vonoprazan → Blocks H⁺/K⁺-ATPase → Reduces stomach acid → Helps relieve acid-related symptoms and supports healing** Vonoprazan does not require activation by stomach acid in the same way that traditional PPIs do. ## DOSAGE & ADMINISTRATION The appropriate dose depends on the condition being treated. For some adult acid-related conditions, **20 mg once daily** may be prescribed. The treatment duration varies according to the indication. For **H. pylori eradication**, vonoprazan is generally used as part of a combination regimen with antibiotics rather than alone. * Take exactly as prescribed. * Swallow the tablet with water. * Follow the specific instructions provided with your medicine. * Do not change the dose or duration without consulting your doctor. * Complete the entire prescribed H. pylori treatment regimen if applicable. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not take two doses together.** ## SIDE EFFECTS Possible side effects include: * Headache * Diarrhea * Constipation * Nausea * Abdominal discomfort * Abdominal pain * Flatulence * Vomiting Most side effects are mild, but persistent or severe symptoms should be discussed with a healthcare professional. ### Serious Side Effects Seek medical attention if you develop: * Severe or persistent diarrhea * Severe abdominal pain * Severe allergic reaction * Facial, lip, tongue, or throat swelling * Difficulty breathing * Severe skin rash or blistering * Unusual muscle spasms, weakness, or irregular heartbeat Long-term or prolonged acid suppression may also be associated with certain nutritional and metabolic complications. ## PRECAUTIONS & WARNINGS ### Long-Term Use Prolonged acid suppression should be used only when medically appropriate. Long-term therapy may be associated with risks such as: * Vitamin B12 deficiency * Low magnesium levels * Certain gastrointestinal infections * Bone fractures in susceptible individuals Your doctor may periodically reassess the need for continued treatment. ### Severe Diarrhea Acid-suppressing medicines can increase susceptibility to certain gastrointestinal infections.
