- Maintenance of healing of erosive esophagitis.
- Pathological hypersecretory conditions, including Zollinger-Ellison Syndrome.
- Treatment of stomach ulcers (benign gastric ulcers) and duodenal ulcers.
- Prevention of NSAID-induced inflammation.

Dosage Information
| Type | Guideline |
|---|---|
| Standard | Pantoprazole is supplied as delayed-release tablets. Dosage is dependent on the patient's condition, age, and response to treatment. It is generally taken 10-20 minutes before a meal with a glass of water. * **Short-Term Treatment of Erosive Esophagitis Associated with GERD:** * **Adults:** 40 mg once daily for up to 8 weeks. * **Children (5 years and older):** * ≥ 15 kg to < 40 kg: 20 mg once daily for up to 8 weeks. * ≥ 40 kg: 40 mg once daily for up to 8 weeks. * **Maintenance of Healing of Erosive Esophagitis:** * **Adults:** 40 mg once daily. Controlled studies did not extend beyond 12 months for this indication. * **Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome:** * **Adults:** 40 mg twice daily. * **General Use (Local Context):** * Typically, one 40 mg tablet once daily. If taking twice daily, take one in the morning and one in the evening. * A higher dose may be initiated if needed, but should be lowered after about 2 weeks when symptoms settle. * Some people may not need to take it every day and can use it only when necessary. * Do not take for longer than 4 weeks unless advised by a doctor.

Safety & Warnings
Common Side Effects
- Common adverse reactions (occurring in >2% of adults) include headache, diarrhea, nausea, abdominal pain, vomiting, flatulence, dizziness, and arthralgia (joint pain).
- For pediatric use (>4%), common effects include upper respiratory infection (URI), headache, fever, diarrhea, vomiting, rash, and abdominal pain.
- Other reported side effects include: Urinary changes (e.
- g.
- , painful urination, increased or decreased urinary frequency), persistent diarrhea (including Clostridium difficile-associated diarrhea), flank pain, allergic reactions (e.
- g.
- , skin rash over the arms, nose, cheeks; severe cutaneous adverse reactions, anaphylaxis, anaphylactic shock, angioedema, bronchospasm, urticaria), constipation, fundic gland polyps (abnormal tissue outgrowths on the upper part of the stomach), subacute cutaneous lupus erythematosus or Cutaneous and Systemic Lupus Erythematosus (a non-scarring skin disease sensitive to sunlight), hypomagnesemia (low magnesium levels) which can lead to dizziness, confusion, muscle twitches, irregular heartbeat, shakiness, increased risk of bone fractures with long-term use, Cyanocobalamin (Vitamin B-12) deficiency which can present as mouth ulcers, pins and needles sensation, or a sore and red tongue, acute tubulointerstitial nephritis, and stomach or intestinal infections.
Serious Warnings
- Black Box Warning: None
- Avoid use if allergic to pantoprazole, any component of the formulation, or any substituted benzimidazole.
- Severe allergic reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute tubulointerstitial nephritis, and urticaria.
- Patients with an existing or history of liver disease should use pantoprazole cautiously, with monitoring of liver enzymes and discontinuation if elevated.
- Exclude malignancy before and during treatment, as symptomatic response does not preclude the presence of gastric malignancy.
- If symptoms do not improve within 2-3 days, or after 2 weeks, consult a doctor.
- Prolonged use (longer than 3 months) can lead to hypomagnesemia (low magnesium levels).
- Long-term therapy (longer than one year) may increase the risk of bone fractures and reduce absorption of cyanocobalamin (Vitamin B-12).
- There is a possible increased risk of gastrointestinal infections (e.
- g.
- , Clostridium difficile-associated diarrhea) and fundic gland polyps with long-term use.
- If taking without a doctor’s prescription, discontinue use after 2 weeks.
- Patients on extended therapy must consult their doctors regarding discontinuation or dose tapering.
- Abrupt cessation may have minimal side effects if not taken for a long time, but caution is advised for long-term users.
- Inform your doctor about all medicines, including antifungals (e.
- g.
- , ketoconazole), methotrexate, HIV medications (e.
- g.
- , atazanavir, nelfinavir, rilpivirine-containing products), rifampicin (antibiotic), warfarin (blood thinner), herbal medicines, or any supplements, as pantoprazole can interact with them.
- Pantoprazole may lower the efficacy of the emergency contraceptive pill EllaOne (ulipristal).
- Inform your doctor about pantoprazole use prior to an endoscopy.
- Avoid consuming alcohol when taking this medicine.
- Although no serious side effects have been reported in nursing females, and the medicine is generally considered safe in pregnant females, it is usually not recommended without consultation; always consult a doctor before use during pregnancy or lactation to prevent complications.
- Store at room temperature, away from excess heat and moisture, pets, and children.
- Lifestyle changes like light exercise, smoking cessation, quitting alcohol, maintaining a healthy weight, avoiding trigger foods (spicy, oily, acidic), eating small meals, not lying down immediately after eating, and elevating the head during sleep can help manage indigestion.
How it Works (Mechanism of Action)
Pantoprazole is a Proton Pump Inhibitor (PPI) that suppresses the final step in gastric acid production. It achieves this by covalently binding to the (H+, K+)-ATPase enzyme system at the secretory surface of the gastric parietal cell. This binding inhibits both basal and stimulated gastric acid secretion, irrespective of the stimulus. The antisecretory effect persists for more than 24 hours.
