Pancreatic digestive enzymes

Pancreatic digestive enzymes are a group of hydrolases, including amylase, lipase, and proteases, secreted by the exocrine pancreas into the duodenum to facilitate the breakdown of macronutrients (StatPearls, 2023). These enzymes are essential for the hydrolysis of carbohydrates, fats, and proteins into smaller, absorbable molecules, thereby maintaining nutritional homeostasis (NIH, 2022). In conditions such as cystic fibrosis, chronic pancreatitis, or following pancreatic surgery, the production or secretion of these enzymes is impaired, leading to exocrine pancreatic insufficiency (EPI) (DrugBank, 2024). EPI results in malabsorption, steatorrhea, and significant weight loss if left untreated (PubMed, 2021). Therapeutic intervention involves Pancreatic Enzyme Replacement Therapy (PERT), where porcine-derived pancrelipase is administered orally to mimic endogenous enzyme activity (StatPearls, 2023). These medications are typically enteric-coated to survive gastric acidity and release active enzymes in the alkaline environment of the small intestine (Wikipedia, 2024). While generally well-tolerated, high doses of these enzymes have been associated with fibrosing colonopathy, particularly in pediatric populations (FDA, 2023).

Pancreatic enzyme replacement therapy (PERT) provides exogenous amylase, lipase, and protease to the duodenum, where they catalyze the hydrolysis of starches, fats, and proteins, respectively, into absorbable components (StatPearls, 2023; DrugBank, 2024).
