Problems solved by technology

Although there are many types of dosage forms, each has certain limitations or disadvantages
For example, it is inconvenient to administer medicine when using tablets, and it is not suitable for a large number of group animals; when powders and premixes are used, they need to be administered through feed, and feed administration requires that the drug and feed be mixed evenly, but the actual operation is relatively uniform. Difficult, easy to cause animal poisoning due to excessive drug intake or too littl

Abstract

The invention relates to the technical field of veterinary medicine preparation, and particularly relates to wettable sulfamonomethoxine (sodium) powder and a preparation method thereof. The wettable sulfamonomethoxine (sodium) powder provided by the invention is added with potassium citrate, a suspending agent and a wetting agent on the basis of effective components of the original medicine; by reasonable medicine proportioning, the invention provides the wettable sulfamonomethoxine (sodium) powder which is easy to disperse evenly in water, convenient to absorb by animals, and small in toxic and side effects. Compared with commercially available compound sulfamonomethoxine (sodium) powder, the wettable sulfamonomethoxine (sodium) powder is convenient to use and good in therapeutic effect. The invention also provides the preparation method of the wettable sulfamonomethoxine (sodium) powder, and the preparation method is simple in technology, low in production cost and suitable to industrialized production.

Description

technical field [0001] The invention relates to the field of veterinary drug preparation, in particular to a wettable sulfamethoxine (sodium) powder and a preparation method thereof. Background technique [0002] Sulfamonomethoxine (sulfamonomethoxine, SMM), also known as bacteriostatic sulfonate, long-acting sulfonamide C, Ds36, sulfa-6-methoxine, 4-sulfa-6-methoxine, the chemical name is N-(6- Methoxy-4-pyrimidinyl)-4-aminobenzenesulfonamide is an odorless, almost tasteless white or off-white crystalline powder that gradually darkens when exposed to light. Sulfamethoxine is easily soluble in dilute hydrochloric acid or alkali solution, slightly soluble in acetone or ethanol, insoluble in water, with a melting point of 204°C to 206°C. [0003] Sulfamethoxine is a long-acting sulfa drug, which is effective against non-enzyme-producing Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Klebsiella, Salmonella, Shigella and other intesti...
