Abstract

The invention discloses a medicine preparation of trypsin enteric coated pellets. The preparation consists of active trypsin powder, a polyol medical excipient, a disintegrant and an enteric coating material containing an anti-adhesion agent. The pellet medicine preparation of the invention is prepared by an extruding-rolling technique. The preparation is used for treating dyspepsia, gastricism caused by pancreatic diseases and dyspepsia of diabetic patients, etc.

Description

Technical field: [0001] The invention relates to pharmaceutical preparations, in particular to a pancreatin enteric-coated pellet and a preparation method thereof. The enteric-coated pellets are very stable in human gastric juice, can quickly disperse in human intestinal solution, and have high biological activity. Background technique: [0002] Pancreatin is a mixture of various enzymes obtained from the pancreas of healthy animals, mainly containing trypsin, pancreatic amylase and pancreatic lipase, which can decompose protein, convert starch into glucose or maltose, and have the ability to digest fat. Pancreatin loses activity quickly under acidic conditions, but has higher activity under neutral or slightly alkaline conditions. It is clinically used for indigestion and digestive disorders caused by pancreatic diseases and indigestion in diabetic patients. [0003] Medicinal pancreatin is white or off-white or slightly yellow powder, slightly smelly, but has no rotten o...
