NULL is a digestive enzyme preparation used in pancreatic enzyme replacement therapy (PERT). It contains a mixture of natural enzymes, lipase, amylase, and protease, which help the body digest fats, carbohydrates, and proteins. NULL is primarily prescribed for people with pancreatic exocrine insufficiency (PEI), a condition in which the pancreas does not produce enough digestive enzymes. By replacing missing enzymes, NULL improves digestion, nutrient absorption, and helps relieve symptoms such as bloating, diarrhoea, fatty stools, and abdominal discomfort.

NULL is derived from porcine (pig) pancreas and closely mimics the natural digestive enzymes normally produced by the human pancreas. In healthy individuals, the pancreas releases enzymes into the small intestine to break down food so nutrients can be absorbed. However, in certain medical conditions, this enzyme production is reduced or absent, leading to poor digestion and malabsorption.

Conditions such as chronic pancreatitis, cystic fibrosis, pancreatic cancer, pancreatectomy (surgical removal of the pancreas), and blockage of the pancreatic duct can all result in pancreatic exocrine insufficiency. Without adequate enzyme replacement, patients may experience persistent diarrhoea, pale or oily stools (steatorrhoea), unintended weight loss, vitamin deficiencies, and general weakness.

NULL works by supplying external digestive enzymes that act directly in the small intestine. These enzymes help break food down into smaller molecules that can be absorbed by the gut. As digestion improves, symptoms gradually reduce, nutritional status improves, and quality of life is significantly enhanced.

NULL is usually taken with meals and snacks to ensure enzymes are available when food reaches the intestine. Treatment is typically long-term and may be lifelong, depending on the underlying condition. Regular follow-up with a healthcare professional ensures the dose remains appropriate and nutritional needs are met.

NULL is indicated for:

• Treatment of Pancreatic Exocrine Insufficiency (PEI): Used to replace missing digestive enzymes in patients whose pancreas does not produce enough enzymes, improving digestion and nutrient absorption.
• Management of Digestive Symptoms in Chronic Pancreatic Disorders: Helps relieve symptoms such as fatty stools (steatorrhoea), bloating, abdominal pain, and diarrhoea associated with conditions like chronic pancreatitis and pancreatic cancer.
• Supportive Therapy After Pancreatic Surgery or in Cystic Fibrosis: Essential for maintaining adequate digestion and nutritional status in patients who have undergone pancreatic surgery or have cystic fibrosis-related enzyme deficiency.

• Physiological Enzyme Replacement: Supplies essential digestive enzymes (lipase, amylase, and protease) that closely mimic natural pancreatic secretions, restoring normal digestion.
• Improves Nutrient Absorption: Enhances the breakdown and absorption of fats, proteins, and carbohydrates, helping prevent malnutrition and vitamin deficiencies.
• Relieves Gastrointestinal Symptoms: Effectively reduces symptoms such as bloating, flatulence, abdominal discomfort, diarrhoea, and fatty stools (steatorrhoea).
• Supports Weight Maintenance and Energy Levels: By improving digestion and absorption, NULL helps prevent unintended weight loss and supports overall nutritional status.
• Suitable for Long-Term Therapy: Well-tolerated and safe for prolonged or lifelong use in chronic pancreatic conditions under medical supervision.

NULL is generally well tolerated when taken at recommended doses.

Common Side Effects (Usually Mild)

• Nausea
• Abdominal discomfort
• Constipation or diarrhoea
• Bloating or gas

Less Common Side Effects

• Mouth irritation (if capsules are opened or chewed)
• Skin rash

Rare but Serious Side Effects

• Fibrosing colonopathy (very high doses, mainly in cystic fibrosis patients)
• Severe allergic reactions (rare): swelling, rash, breathing difficulty

Seek medical advice if you experience severe abdominal pain, persistent diarrhoea, or allergic symptoms.

• Dosage: The dose is individualised and depends on the severity of pancreatic enzyme deficiency, body weight, age, and fat content of meals. Doses are typically measured in lipase units and taken with each main meal and snack.
• Administration: Take NULL during or immediately after meals. Swallow capsules or tablets whole with water. Do not chew, crush, or break enteric-coated preparations, as this can destroy the enzymes and irritate the mouth or stomach.
• Consistency: Take NULL with every meal or snack containing fat to ensure effective digestion and symptom control.

NULL works by replacing digestive enzymes that are normally produced by the pancreas but are deficient in certain medical conditions.

• Enzyme Replacement Action: NULL contains lipase, amylase, and protease, which act directly in the small intestine to digest fats, carbohydrates, and proteins.
• Targeted Intestinal Release: Many formulations are enteric-coated to protect the enzymes from stomach acid, ensuring they are released in the small intestine where digestion occurs.
• Restoration of Normal Digestion: By enabling proper breakdown of food, NULL improves nutrient absorption, reduces malabsorption-related symptoms, and supports overall gastrointestinal function.
• Local Action: NULL acts locally within the gastrointestinal tract and is not significantly absorbed into the bloodstream, minimising systemic side effects.

• Always take with meals or snacks.
• Do not skip doses when eating.
• Do not chew capsules.
• Maintain regular follow-up for nutritional monitoring.
• Adjust dose based on meal size and fat content (as advised).

• Store below 25°C.
• Protect from heat and moisture.
• Keep the container tightly closed.
• Keep out of reach of children.

• NULL must always be taken with food.
• Extremely hot foods may damage enzymes if capsules are opened.
• No specific dietary restrictions, but a moderate-fat diet may improve symptom control.

• Antacids (calcium carbonate, magnesium hydroxide): May reduce enzyme effectiveness if taken simultaneously.
• Iron supplements: Enzyme therapy may reduce iron absorption.
• Acarbose: NULL may reduce its glucose-lowering effect.

Use with caution in patients with:

• Acute pancreatitis (avoid during acute flare unless advised)
• Gout or high uric acid levels (very high doses may increase uric acid)
• Pork protein allergy (contraindicated)

Dosage is individualised based on age, weight, diet, and severity of enzyme deficiency. Typical doses are measured in lipase units and adjusted according to fat intake. Follow your doctor’s instructions precisely.

Overdose is uncommon but may cause gastrointestinal irritation or increased uric acid levels. Seek medical advice if overdose is suspected.

If you forget a dose, take it with your next meal. Do not take a double dose to make up for a missed one.
