Pansped

Description

Pansped Tablet (Pantoprazole Sodium Sesquihydrate)

Overview: Pansped Tablet, containing Pantoprazole Sodium Sesquihydrate, is a proton pump inhibitor (PPI) that effectively reduces the production of stomach acid. It works by blocking the final step of acid secretion in the gastric parietal cells, thereby inhibiting both basal (resting) and stimulated acid output. It is prescribed for various acid-related gastrointestinal conditions.

Indications for Use

Pansped Tablet is used for the treatment and management of:

• Peptic Ulcer Disease (PUD), including duodenal and gastric ulcers.
• H. pylori infection (as part of an eradication regimen).
• Gastro-Oesophageal Reflux Disease (GERD), including erosive oesophagitis.
• Zollinger-Ellison Syndrome and other pathological hypersecretory conditions.
• Oesophagitis.
• Acid-related Dyspepsia.
• NSAID-associated ulceration (both treatment and prophylaxis).
• Ulcers resistant to H2 receptor antagonists.
• Prophylaxis for Gastrointestinal (GI) bleeding from stress.
• Prophylaxis for acid aspiration syndrome during induction of anesthesia.

Dosage Information

Adults (Oral):

• Erosive Esophagitis Associated With GERD:
  • Treatment: 40 mg orally once daily for 8-16 weeks.
  • Maintenance of Healing: 40 mg orally once daily.
  • Alternatively, if oral therapy is inappropriate or not possible for short-term treatment: 40 mg IV once daily for 7-10 days; switch to oral once the patient is able to swallow.
• Zollinger-Ellison Syndrome:
  • Oral: Initially 40 mg orally once daily; doses up to 240 mg/day may be administered in some patients.
  • If IV is necessary: 80 mg IV infusion every 8-12 hours for up to 7 days; switch to oral once the patient is able to swallow.
• Peptic Ulcer Disease:
  • Duodenal ulcer: 40 mg orally once daily for 2-4 weeks.
  • Gastric ulcer: 40 mg orally once daily for 4-8 weeks.

Elderly:

• No dosage adjustment is typically needed.

Hepatic Impairment:

• Maximum daily dose: 20 mg/day or 40 mg on alternate days.

Pediatric Dosage (Oral)

• Erosive Esophagitis Associated With GERD:
  • <5 years: Safety and efficacy have not been established.
  • >5 years:
    • 15 kg to <40 kg: 20 mg orally once daily for up to 8 weeks.
    • 40 kg or greater: 40 mg orally once daily for up to 8 weeks.

Renal Impairment

• No dosage adjustment is typically needed.

Administration

• Controlled-release tablets (like Pansped Tablet): Should be taken on an empty stomach, 1 hour before meals. Swallow whole; do not chew or crush.
• Normal release tablets (if applicable for other Pantoprazole products): May be taken with or without food.

Intravenous (IV) Preparation and Administration (for Pantoprazole Sodium Sesquihydrate injection, typically if oral is not feasible):

• GERD with a history of erosive esophagitis (15-minute infusion): Reconstitute the vial with 10 mL Normal Saline (NS), then further dilute with 100 mL Dextrose 5% in Water (D5W), NS, or Lactated Ringer’s (LR) to achieve a final concentration of 0.4 mg/mL. Infuse over 15 minutes, at a rate no more than 3 mg/min (7 mL/min).
• Zollinger-Ellison Syndrome:
  • 15-minute infusion: Reconstitute each vial with 10 mL NS. Combine 2 vials and further dilute with 80 mL D5W, NS, or LR to a total volume of 100 mL (concentration 0.8 mg/mL). Infuse over 15 minutes, at a rate no more than 6 mg/min (7 mL/min).
  • 2-minute injection: Reconstitute with 10 mL NS to a final concentration of 4 mg/mL.

Contraindications

Pansped Tablet is contraindicated with concomitant use of:

• Rilpivirine
• Atazanavir
• Nelfinavir
• It is also contraindicated during lactation.

Precautions

• Gastric malignancy should be ruled out before initiating treatment, as symptom improvement might mask an underlying serious condition.
• Consider zinc supplementation during IV therapy in patients who are prone to zinc deficiency (relevant if a patient is switched from IV to oral).
• Pregnancy: Use with caution; consult a healthcare professional.
• Monitoring Parameters: Monitor magnesium levels prior to initiation of therapy and periodically during prolonged use.
• Lactation: It is not known whether pantoprazole is distributed into breast milk; therefore, its use is generally not recommended during breastfeeding.

Interactions

• Increased risk of digoxin-induced cardiotoxic effects.
• Increased risk of hypomagnesaemia with concomitant use of diuretics.
• May increase INR (International Normalized Ratio) and prothrombin time in patients on warfarin.
• May increase serum concentration of methotrexate and saquinavir.
• Delayed absorption and decreased bioavailability when taken with sucralfate; separate administration times.
• Decreased absorption of oral ketoconazole and itraconazole.
• Potentially Fatal: May significantly decrease serum levels and pharmacological effects of rilpivirine, atazanavir, and nelfinavir, leading to loss of antiviral efficacy.

• Erythema multiforme

Mechanism of Action

Pantoprazole is a substituted benzimidazole, categorized as a proton pump inhibitor (PPI). Its therapeutic action involves irreversibly binding to and inhibiting the H+/K+ ATPase enzyme system (commonly known as the proton pump) within the gastric parietal cells. By blocking this final step of acid secretion, pantoprazole effectively suppresses both basal (resting) and stimulated acid production in the stomach.
