INDICATION

Vonoglob 20mg Tab 14s is a potent potassium-competitive acid blocker indicated for the treatment of a wide range of acid-related gastrointestinal disorders requiring rapid and sustained gastric acid suppression. It is primarily prescribed for gastroesophageal reflux disease (GERD), including both non-erosive reflux disease and erosive esophagitis, where it effectively reduces symptoms such as heartburn, regurgitation, and epigastric discomfort. It is also indicated for the healing and prevention of gastric and duodenal ulcers, particularly in patients with recurrent ulcer disease or those who are resistant to conventional proton pump inhibitor therapy.

MECHANISM OF ACTION

Vonoprazan exerts its therapeutic effect by competitively inhibiting the potassium-binding site of the gastric H⁺/K⁺-ATPase enzyme located on the parietal cells of the stomach lining. This mechanism directly blocks the final step of gastric acid secretion, resulting in a rapid onset and prolonged acid suppression. Unlike traditional proton pump inhibitors, vonoprazan does not require activation in an acidic environment, allowing it to function effectively from the first dose. The sustained elevation of gastric pH promotes mucosal healing, reduces acid-mediated injury, and improves patient outcomes in ulcer healing and reflux control.

DOSAGE AND ADMINISTRATION

●     GERD and erosive esophagitis: 20mg once daily for 4–8 weeks, depending on severity and clinical response.

●     Gastric/duodenal ulcers: 20mg once daily for 6–8 weeks, with duration individualized based on endoscopic findings.

●     H. pylori eradication therapy: 20mg twice daily in combination with antibiotics such as amoxicillin and clarithromycin for 7–14 days.

●     Can be taken with or without meals due to its acid-stable nature

●     Maintain consistent daily dosing for optimal therapeutic outcomes.

SIDE EFFECTS

●     Common: Headache, diarrhea, nausea, abdominal pain, flatulence

●     Less common: Constipation, dizziness, elevated liver enzymes, skin rash, pruritus

NOT RECOMMENDED IN

Vonoglob is contraindicated in patients with known hypersensitivity to vonoprazan or any excipient in the formulation. It should be used with caution in individuals with moderate to severe hepatic impairment due to altered drug metabolism. Prolonged use without an appropriate clinical indication is not recommended, as sustained acid suppression may increase the risk of gastrointestinal infections, nutrient malabsorption (including vitamin B12 deficiency), and electrolyte disturbances. Its use during pregnancy and breastfeeding has not been fully established and should only be considered if the potential benefits outweigh the risks under medical supervision.

DRUG INTERACTIONS

Vonoprazan may reduce the absorption of medications that depend on an acidic gastric environment, including antifungal agents such as ketoconazole and certain antiretroviral drugs like atazanavir. It is primarily metabolized via CYP3A4 pathways; therefore, concomitant use with strong inhibitors or inducers of this enzyme may alter drug levels. Caution is advised when co-administered with medications that have a narrow therapeutic index, as changes in gastric pH may affect their pharmacokinetics.

STORAGE INSTRUCTIONS

Store below 30°C in a cool, dry place away from heat, moisture, and direct sunlight. Keep in original packaging and out of reach of children.
