Development of pancreatic enzyme microsphere technology and US findings with Pancrease in the treatment of chronic pancreatitis.
Enzyme replacement therapy is a vital aspect of the management of patients with chronic pancreatic insufficiency. However, pharmaceutical technology in the manufacture of enzyme products has advanced significantly only in the last decade. In the late 1970s, Johnson & Johnson scientists developed novel pH-sensitive enteric-coated microspheres of pancrelipase (Pancrease) that could be encapsulated for convenient administration. The increased efficiency of the formulation allowed lower daily doses than had been required with conventional enzyme products. In vitro studies indicate that the microspheres disintegrate at a pH appropriate for patients with cystic fibrosis and chronic pancreatitis. Clinical studies of Pancrease in chronic pancreatitis demonstrate a significant improvement in fecal fat excretion, fat utilization, stool weight, and stool frequency, as well as significant weight gain and improved quality of life of patients. Pancrease represents a major advance in the clinical management of chronic pancreatic insufficiency.
