Problems solved by technology

But in actual application, the granule product of this medicine still has some shortcomings and deficiencies, specifically manifested in: 1. Since the preparation method of Lemai granule adopts traditional technology, the temperature for drying the medicinal material and the fineness of pulverization There are no specific requirements, so that some effective active ingredients in the preparation are lost, resulting in a decrease in clinical efficacy; 2. The dosage of granules is large, and the bioavailability is low; 3. The content of the main drug in granules is not easy to control, and the accuracy of patients' taking is poor; 4. It is easy to cause microbial contamination in the process of production and storage
