Problems solved by technology

[0007] However, the specific gravity of mitiglinide calcium is low, it is easy to fly, and it is difficult to sieve. At the same time, mitiglinide calcium has poor water solubility and cannot be quickly dispersed in water. It is difficult to fully dissolve as a drug, which makes its active ingredient release slowly. Lead to low efficacy intensity, which is not conducive to the treatment of diabetes

Description

technical field [0001] The invention relates to a mitiglinide calcium preparation and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] Diabetes is a common and frequently-occurring disease, and the number of its patients is increasing rapidly with the improvement of people's living standards, population aging, changes in lifestyle, and advances in diagnostic techniques. According to the relevant data of WHO, the prevalence rate, disability rate, mortality rate and degree of harm of diabetes rank the third among non-communicable diseases, and it has become the third serious threat to human health after cardiovascular and cerebrovascular diseases and tumors. This disease not only brings great suffering to patients, greatly affects the quality of life, but also brings a heavy economic burden to the society. Therefore the majority of clinicians and diabetic patients are eagerly looking forward to having more and ...
