Premix

The main differences between powder,premixed agent, granule are as follows:

Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing. 

Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation. 

As a dosage form of feed drug additive, it is specially used for mixed feeding.

Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows: 

1.the production method is different 

1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation. 

2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate. 

3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation. 

2.different characteristics

1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take. 

2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed. 

3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.
