Background:
Pancreatic enzyme preparations are a life-saving substitution for a pivotal physiological function of the entire organism that is impaired in chronic pancreatitis, cystic fibrosis and other diseases with exocrine pancreatic insufficiency. Pancreatic enzyme preparations, generically called pancreatin, are not alike. Rather, they present a broad variety of pancreatin composition.
Aim:
The properties of a set of commercially available pancreatin preparations were investigated in light of the physiological tasks such enzymes must fulfill during the normal digestive process.
Methods:
Measurements of size, surface, acid resistance, release of enzymes, pharmacokinetics and batch consistency were undertaken.
Results:
Although all pancreatin preparations contain the declared lipase units and are acid-stable, a wide variation was observed in the particle size (pyloric passage), specific surface area and release kinetics of lipase activity at pH 6 (duodenum).
Conclusion:
At present, available pancreatin preparations vary widely with respect to investigated parameters, which may have consequences for facilitating optimal digestion.

Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...

Cells and Secretions of the Pancreas
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
