Pantoprazole Aurobindo (Pantoprazole)

Pantoprazole is a proton pump inhibitor that acts on the gastric acid secretion pathway.

• Gastro‑oesophageal reflux disease (GERD): Provides symptomatic relief and promotes healing of the oesophageal lining.
• Erosive esophagitis: Facilitates ulcer healing within the oesophagus.
• Peptic ulcer disease: Supports ulcer healing and reduces risk of recurrence.
• Zollinger‑Ellison syndrome: Controls excessive gastric acid secretion.

• Pantoprazole selectively inhibits the H+/K+‑ATPase enzyme (the gastric proton pump) located on the parietal cells of the stomach lining. By binding covalently to the pump’s cysteine residues, it blocks the final step of acid secretion, leading to a sustained increase in gastric pH and reduced acidity.

Pantoprazole may cause adverse reactions, most of which are mild and reversible.

Common Side Effects

• Headache: mild and transient.
• Diarrhea: loose stools that usually resolve without treatment.
• Nausea: occasional feeling of queasiness.
• Abdominal pain: mild discomfort in the stomach area.
• Flatulence: increased intestinal gas.
• Constipation: reduced bowel movements.

Serious or Rare Side Effects

• Severe allergic reaction: rash, itching, swelling, or difficulty breathing.
• Clostridioides difficile infection: persistent watery diarrhea.
• Low magnesium levels: muscle cramps, irregular heartbeat.
• Bone fractures: increased risk with long‑term use.
• Liver enzyme elevation: abnormal liver function tests.
• Acute interstitial nephritis: kidney inflammation presenting with fever and rash.

Before initiating Pantoprazole therapy, consider the following safety measures:

• Assess renal function: adjust use in severe renal impairment.
• Review concomitant medications: potential for altered absorption of drugs requiring acidic pH.
• Monitor long‑term use: evaluate need for periodic reassessment after 12 months.
• Pregnancy and lactation: weigh benefits against potential risks; use only if clearly indicated.
• Elderly patients: start at the lowest effective dose and monitor for fractures.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Pantoprazole can affect the pharmacokinetics of several medicines. Review these interactions carefully.

Major Interactions (Avoid)

• Antifungal agents (ketoconazole, itraconazole): reduced absorption and loss of efficacy.
• HIV protease inhibitors (atazanavir, nelfinavir): markedly decreased plasma concentrations.

Moderate Interactions (Monitor Closely)

• Antiplatelet drug clopidogrel: possible reduction in antiplatelet effect.
• Warfarin: may increase INR values, requiring closer monitoring.
• Methotrexate: decreased renal clearance can raise serum levels.
• Digoxin: modest increase in serum concentration.
• Oral contraceptives: potential reduction in hormonal efficacy.
