5克邻苯二甲酸醋酸纤维素溶解在60毫升的二甲基亚砜中配成溶液。在此溶液中散布10克日本药典规格的胰酶粉,这个分散物在300毫升细液滴状(200～500微米)液态石腊中(日本药典19CP.25℃),在螺旋桨搅拌下变成乳剂。继续搅拌数分钟,直至乳化达稳定状态、然后加入100毫升4:1的水丙酮溶液,作为乳剂的非溶剂,从而形成微型胶囊。用滤布 5 grams of cellulose acetate phthalate dissolved in 60 ml of dimethyl sulfoxide dubbed solution. To this solution, 10 g of pancreatin powder of the Japanese Pharmacopoeia specifications was dispersed, and the dispersion became (propelled with propeller stirring) in 300 ml of fine paraffin (200 to 500 μm) liquid paraffin (Japanese Pharmacopoeia 19, 25 ° C) Emulsion. Continue stirring for a few minutes until emulsification reaches a steady state, then add 100 ml of 4: 1 aqueous acetone solution as a non-solvent for the emulsion to form microcapsules.
