Pantoprazole Arrow (Pantoprazole)

Pantoprazole Arrow is a proton pump inhibitor indicated for conditions where suppression of gastric acid is required.

• Gastroesophageal reflux disease (GERD): provides symptomatic relief and promotes healing of esophageal irritation.
• Erosive esophagitis: accelerates mucosal healing and reduces recurrence of lesions.
• Zollinger‑Ellison syndrome: controls excessive gastric acid production associated with gastrin‑secreting tumors.
• Prevention of NSAID‑induced gastric ulcers: lowers ulcer incidence in patients receiving non‑steroidal anti‑inflammatory drugs.

• Pantoprazole irreversibly binds to the H+/K+ ATPase enzyme (the gastric proton pump) located on the secretory surface of parietal cells. By inhibiting this final step of acid secretion, it markedly reduces both basal and stimulated gastric acid output, leading to an increased gastric pH and allowing ulcer healing and symptom control.

Pantoprazole Arrow may be associated with a range of adverse reactions.

Common Side Effects

• Headache: mild to moderate intensity, often transient.
• Diarrhea: watery stools, usually self‑limiting.
• Nausea or abdominal discomfort: may occur during infusion.
• Flatulence or constipation: gastrointestinal motility changes.

Serious or Rare Side Effects

• Severe allergic reactions (anaphylaxis, angioedema): require immediate medical attention.
• Clostridioides difficile‑associated diarrhea: can be life‑threatening.
• Hypomagnesemia or electrolyte disturbances: may cause muscle cramps or cardiac arrhythmias.
• Hepatic enzyme elevation: monitor liver function tests.
• Stevens‑Johnson syndrome or toxic epidermal necrolysis: rare but severe skin reactions.

When using Pantoprazole Arrow, consider the following precautions.

• Renal function assessment: adjust therapy in severe renal impairment.
• Magnesium monitoring: check serum levels during prolonged treatment.
• Hepatic impairment: use with caution in patients with liver disease.
• Infection risk: be vigilant for signs of C. difficile infection.
• Elderly patients: start at the lowest effective dose and monitor closely.
• Store at room temperature: keep in original container, protect from moisture and light.

Pantoprazole Arrow can interact with several medications; awareness of interaction severity is essential.

Major Interactions (Avoid)

• Atazanavir or other protease inhibitors: reduced antiviral absorption.
• Rilpivirine: decreased plasma concentrations leading to therapeutic failure.

Moderate Interactions (Monitor Closely)

• Warfarin: potential increase in anticoagulant effect, monitor INR.
• Digoxin: possible elevation of serum digoxin levels.
• Methotrexate: reduced clearance, monitor for toxicity.
• Clopidogrel: diminished antiplatelet activity, assess bleeding risk.
