Dosing in Patients Without CF
ZENPEP® is the highest-strength PERT available on the market1
- Dosing range is 500 to 2,500 lipase units/kg/meal (children ≥4 years and adults). Not to exceed 10,000 units/kg/day
- Patients may be dosed on a fat ingestion–based or an actual body weight–based dosing scheme

The American College of Gastroenterology (ACG) recommends PERT in patients with EPI and CP at an adequate dosage of at least 40,000 to 50,000 lipase units per meal. 2
NORMAL PANCREATIC FUNCTION
A healthy pancreas produces between 480,000 and 960,000 lipase units per meal. 3*

CF=cystic fibrosis; CP=chronic pancreatitis; EPI=exocrine pancreatic insufficiency; PERT=pancreatic enzyme replacement therapy.
* The estimated “normal” amount of pancreatic enzyme secretion 2 hours after a meal varies with content and volume of meal ingested. Data estimated from studies using test meals of 300 to 600 k/cal.
Key challenges when treating EPI with PERT include4,5:
Underdosing
Compliance
Pill burden
Only ZENPEP meets ACG dosing recommendations for patients with EPI due to CP in just 1 capsule1,2
DOSING RECOMMENDATIONS FOR 40,000 LIPASE-UNIT CAPSULES



- This chart is intended to be a guide; ZENPEP capsules represent nearest capsule count within recommended dosing range
- The dose of ZENPEP should be individualized based on weight, clinical symptoms, the degree of steatorrhea present, and the fat contents of the patient’s diet1
- Dosing should not exceed the recommended maximum dosage set forth by the Cystic Fibrosis Foundation Consensus Conferences Guidelines1
Dosing Calculator for ZENPEP
Use the app below to calculate the per-meal dose of ZENPEP for your patients with EPI due to CF or other conditions. ZENPEP is not interchangeable with any other pancrelipase product. Therapy should be initiated at the lowest recommended dose and gradually increased. The dosage of ZENPEP should be individualized based on clinical symptoms, the degree of steatorrhea present, and the fat content of the diet. Dosing should not exceed the recommended maximum dosage set forth by the Cystic Fibrosis Foundation Consensus Conferences Guidelines.
