1. Clinical & Scientific Overview
Pepsin (TIP-MED-000295, Reference Code [5.13]-C25) is classified under
Gastrointestinal & Hepatobiliary Medicines (Ch 05) as a Exocrine Pancreatic / Digestive Enzyme Replacement (Lipase, Amylase, Protease).
Within the Indian regulatory and compendial framework, it is governed under Non-Schedule / OTC or Schedule K Permitted Preparation (Medical Supervision Recommended for High-Dose/Therapeutic Regimens).

3. Mechanism of Action & Pharmacodynamics
Exocrine Pancreatic / Digestive Enzyme Replacement (Lipase, Amylase, Protease) acting on target receptor/enzyme pathways in Gastrointestinal & Hepatobiliary Medicines (Ch 05): clinical efficacy is mediated via Exocrine Pancreatic / Digestive Enzyme Replacement (Lipase, Amylase, Protease) for Pancreatin (Creon): Exocrine Pancreatic Insufficiency (EPI) due to chronic calcific pancreatitis, post-pancreatectomy, pancreatic cancer, or cystic fibrosis (prevents steatorrhoea and fat-soluble vitamin malabsorption). Fungal Diastase/Pepsin (Aristozyme/Unienzyme): Symptomatic adjunct in functional postprandial fullness/indigestion..
4. Therapeutic Indications & Evidence-Supported Uses
- Pancreatin (Creon): Exocrine Pancreatic Insufficiency (EPI) due to chronic calcific pancreatitis, post-pancreatectomy, pancreatic cancer, or cystic fibrosis (prevents steatorrhoea and fat-soluble vitamin malabsorption)
- Fungal Diastase/Pepsin (Aristozyme/Unienzyme): Symptomatic adjunct in functional postprandial fullness/indigestion
🇮🇳 Jurisdiction & Indication Note: Indications and schedules reflect Indian compendial and regulatory records (CDSCO / Indian Pharmacopoeia & NFI / NLEM 2022). Where international reference labels (US FDA DailyMed / NCBI StatPearls) are cited for pharmacokinetic or mechanistic parameters, international approvals do not automatically imply CDSCO approval in India.
5. Educational Dosage Context, Formulations & Administration
Educational Dosing & Regimen Summary: General Adult Reference: Pancreatin (EPI): 25,000 to 50,000 Lipase units with each main meal and 10,000 to 25,000 units with snacks (titrated to control fatty stools). Fungal Diastase/Pepsin: 1 tablet/capsule or 5–10 mL liquid with or immediately after meals. Follow physician prescription.
Administration & Meal Timing: MUST be taken DURING or immediately with the meal (for Creon: take half the capsules at the start of the meal and the remainder mid-meal) with plenty of cold or room-temperature liquid so the enzymes mix intimately with the food chyme. | With breakfast, lunch, dinner, and fat-containing snacks.
6. Pharmacokinetics, Metabolism & Renal/Hepatic Adjustment
Follows class pharmacokinetic profile detailed in parent monograph [5.13].
Renal & Hepatic: Act locally within the gastrointestinal lumen without systemic absorption; monitor serum uric acid if high-dose pancreatin is used in renal impairment or gout.
Renal & Hepatic: Act locally within the gastrointestinal lumen without systemic absorption; monitor serum uric acid if high-dose pancreatin is used in renal impairment or gout.
Renal & Hepatic: Act locally within the gastrointestinal lumen without systemic absorption; monitor serum uric acid if high-dose pancreatin is used in renal impairment or gout.
7. Contraindications, Precautions & High-Risk Warnings
- Contraindicated in acute pancreatitis or acute flare of chronic pancreatitis during the initial fasting phase, and porcine protein hypersensitivity (for porcine pancreatin). Warning for Unienzyme (containing Activated Charcoal): Activated charcoal adsorbs other oral medications in the stomach!
Key Clinical Precautions: Renal & Hepatic: Act locally within the gastrointestinal lumen without systemic absorption; monitor serum uric acid if high-dose pancreatin is used in renal impairment or gout.
8. Adverse Effects Profile
- Mild abdominal cramping, nausea, bloating, perianal irritation (if high doses cause rapid transit), hyperuricaemia (with high-dose porcine pancreatin).
- Fibrosing colonopathy (colonic strictures—rare, associated with massive doses >10,000 lipase units/kg/day), oral mucosal ulceration if pancreatin minimicrospheres are chewed and retained in the mouth.
9. Major Drug–Drug, Drug–Food & Drug–Herb Interactions
- Antagonises Acarbose and Voglibose! (Amylase in digestive enzyme preparations breaks down complex starches into simple sugars, directly defeating the alpha-glucosidase block of acarbose/voglibose)
- Furthermore, preparations containing activated charcoal (like Unienzyme) bind and inactivate concurrent oral drugs—space other medications by ≥2 hours! Acid suppression (PPIs) actually enhances pancreatin efficacy by preventing gastric acid destruction of lipase
10. Clinical Monitoring, Patient Counselling & Storage
Clinical & Laboratory Monitoring: Monitor clinical parameters per parent monograph [5.13].
Pharmacist Patient Counselling Points:
- Patient Counselling Checklist: Swallow Creon capsules whole during the meal with room-temperature water. If an elderly patient cannot swallow the large Creon capsule, it may be carefully opened and the tiny spheres mixed into a spoonful of soft acidic food (such as curd/yogurt or applesauce) and swallowed immediately without chewing, followed by a glass of water so no spheres remain stuck to the gums.
- Meal & Clock Timing Instruction: MUST be taken DURING or immediately with the meal (for Creon: take half the capsules at the start of the meal and the remainder mid-meal) with plenty of cold or room-temperature liquid so the enzymes mix intimately with the food chyme. (With breakfast, lunch, dinner, and fat-containing snacks.)
- Missed Dose Protocol: If remembered after the meal is already finished, SKIP the missed dose—taking digestive enzymes on an empty stomach without food has no benefit.
- Geriatric Dispensing Pearl: In elderly diabetics taking Acarbose or Voglibose, never dispense over-the-counter digestive enzyme syrups/tablets. If dispensing Unienzyme (which contains charcoal), warn the patient to keep it 2 hours away from their BP, diabetes, and heart tablets.
Storage, Stability & Dispensing Safeguards: Store below 25°C–30°C in original moisture- and light-resistant packaging out of reach of children. Available forms: Pancreatin EC Minimicrosphere Capsules: 10,000, 25,000, 40,000 Ph.Eur. Lipase Units; Fungal Diastase (50 mg) + Pepsin (10 mg) Liquids/Tablets/Capsules
