Abstract

A natto kinase oral emulsion is composed of an oil phase and an aqueous phase; wherein the aqueous phase is a natto kinase water solution with a concentration of 100 to 10000 IU/mL; and the oil phase is composed of the following components in percentage by the total weight of the oil phase: 8 to 12% of phosphatide, 4 to 6% of bee wax, 0.4 to 1% of deoxycholic acid, 1.25 to 5% of auxiliary emulsifier, and the balance being oil. The invention also provides a preparation method of the oral emulsion. The oral emulsion can prominently improve the thermal stability and preservation stability of natto kinase, and improve the drug effect of orally-taken natto kinase at the same time. Furthermore, the preparation method has the advantages of simple operation, low production cost, and easiness for large-scale production.

Description

technical field [0001] The application relates to the field of pharmaceutical preparations, more specifically, to a nattokinase oral emulsion, a preparation method thereof, and a capsule filled with the emulsion. Background technique [0002] 1. Brief Introduction of Nattokinase [0003] Natto (natto) originated in ancient China and is a food made from soybeans fermented by Bacillus natto. During the Tang Dynasty, natto was introduced to Japan by Master Jianzhen. It first developed in temples, and gradually became popular among Japanese people, occupying an important position on the Japanese table. In the 1980s, Hiroyuki Sumi (必见洋行), who was engaged in thrombus research in the United States, used artificial thrombus plates to screen a large number of various natural products in order to find new antithrombotic substances. In an accidental attempt, he discovered that natto has a strong ability to dissolve artificial thrombus. After in-depth research, he finally isolated a s...
