preparation example Construction

[0050] The present invention also provides a preparation method of pancreatin enteric-coated pellets, including the preparation of pancreatin enteric-coated pellets, the preparation of enteric liquid and the preparation of pancreatin enteric-coated pellets, specifically comprising the following steps:

[0051] Step 1: Pass the formulated amount of active pancreatin powder, diluent, disintegrant, and binder through a 100-mesh sieve, mix well, and add an appropriate amount of water to make a moist, uniform and plastic soft material;

[0052] Step 2: put the soft material prepared in step 1 into an extruder, and extrude thin strips of equal diameter;

[0053] Step 3: Quickly add the equal-diameter strip-shaped extrudates prepared in step 2 into the spheronizer in batches, and set the parameters of the spheronizer so that the drug particles are rounded;

[0054] Step 4: Dry the spherical drug granules prepared in Step 3 at 37°C for 12-20 hours to obtain pancreatin pellets;

Abstract

The invention belongs to the pharmaceutical preparation technology field and discloses a pancreatin enteric coating pellet. The pancreatin enteric coating pellet is prepared from a pancreatin pellet, a separant and an enteric coating liquid. The formula of the pancreatin pellet comprises pancreatin powder, diluents, disintegrating agents and adhesives. The formula of the enteric coating liquid comprises enteric coating materials, antitackiness agents, plasticizers and purified water. The invention also provides a preparation method for the pancreatin enteric coating pellet. The pancreatin enteric coating pellet is advantaged by high stability, low irritability, high safety factor and rapid drug release degree. The preparation method is simple and practicable, the quality is reliable, and the method can be implemented and worthy of further industrial popularization.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a pancreatin enteric-coated pellet and a preparation method thereof. Background technique [0002] Pancreatin is a mixed enzyme extracted from the pancreas of pigs, cattle, sheep and other animals. Pancreatin contains a variety of enzymes, mainly including trypsin, pancreatic amylase, pancreatic lipase, trypsin, carboxypeptidase and so on. Among them, trypsin can decompose protein, pancreatic amylase can convert starch into maltose or glucose, and pancreatic lipase has the ability to digest fat. Clinically, pancreatic enzymes are mainly used for diseases such as indigestion and digestive disorders caused by the pancreas. [0003] Pancreatin will quickly lose its activity under acidic conditions, but has higher activity under neutral and alkaline conditions. Therefore, pancreatic enzyme preparations should be acid-resistant and have a high releas...
