Abstract

The present invention is double time phase protamine zinc insulin injection (30 %) and its preparation process, and belongs to the field of medicine preparation technology. The double time phase protamine zinc insulin injection (30 %) consists of insulin 100000 IU, isosmotic agent 35-45 g, preservative 5.5-7 g, pH regulator 12-12.5 g and fish protamine sulfate 0.21-0.42 g, and has pH value of 6.9-7.8. Its preparation process includes the steps of preparing neutral insulin injection, preparing low protamine zinc insulin injection, and mixing these two kinds of injection. The double time phase protamine zinc insulin injection (30 %) has two forms of insulin, including one in solution for quick acting and the other in precipitate with combined fish protamine sulfate as the middle acting phase. It has less required injection times.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to biphasic protamine zinc insulin injection (30%) and a preparation method thereof. Background technique [0002] With the economic development of China in the past 20 years, people's lifestyle has undergone tremendous changes, and the incidence of diabetes, the so-called "rich man's disease", has greatly increased. Statistics show that in China, the number of diabetic patients has increased by nearly 5 times in the past 15 years. A survey conducted among more than 40,000 urban and rural residents in 11 provinces and cities in China found that the prevalence of diabetes has increased from 0.6-0.7% in 1980 to 3.21% at present. At present, it is estimated that the total number of diabetic patients reaches nearly 40-50 million, of which the number of patients aged 20 to 79 reaches nearly 30 million, ranking second only to India in the world. Diabetes is harmful, mainly bec...
