Method for effectively increasing material mixing efficiency during medicine preparation

Abstract

The invention provides a method for effectively increasing material mixing efficiency during medicine preparation. The method is characterized by comprising the following steps of weighing materials, adding ethanol, carrying out stirring, carrying out water adding, carrying out stirring and carrying out condensing recovery. According to the method, the preparation method is simple, and the material mixing efficiency during the medicine preparation is effectively increased. The ethanol serves as a dispersing medium, so that the problem that a macromolecular compound is hard to rapidly and uniformly dissolve in water is solved; and the ethanol is readily available and can be recycled, so that the use cost of the method is low.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a method for effectively improving the mixing efficiency of materials in pharmaceutical preparation. Background technique [0002] Polymer water-soluble compounds are also called water-soluble resins or water-soluble polymers. The so-called water-soluble polymer is a kind of strong hydrophilic polymer material, which can be dissolved or swelled in water to form an aqueous solution or dispersion system. There are a large number of hydrophilic groups in the molecular structure of water-soluble polymers. Hydrophilic groups can usually be divided into three categories: ① cationic groups, such as tertiary amino groups, quaternary amino groups, etc.; ② anionic groups, such as carboxylic acid groups, sulfonic acid groups, phosphoric acid groups, sulfuric acid groups, etc.; ③ polar groups. Non-ionic groups, such as hydroxyl groups, ether groups, amine groups, amid...

Problems solved by technology

[0003] In practice, the polymer water-soluble compound powder is dissolved in water, but due to the different contact time of the polymer compound powder, the powder that first touches the water will easily form agglomerates to form a colloidal substance and then the powder that touches the water. It needs to be heated and stirred continuously for a long time to completely dissolve the polymer water-soluble compound (at least 2 hours), and the agglomerated polymer water-soluble compound will appear as a transparent gel, which is difficult to find in water, and finally It also needs to be filtered and removed, the operation process is time-consuming and laborious, and it will also cause waste of materials
