Embodiment example 3

[0052] According to the production technique provided by the present invention, the 5% povidone-iodine solution of production, its stability inspection is to inspect by " Chinese Veterinary Pharmacopoeia " 2010 edition one, and inspection item comprises: character, pH value, identification, effective Iodine content, specifications. The standards are as follows: traits: reddish-brown liquid; PH value: 3.0-6.5; identification: (1) Take 1-5 drops of this product, add 10 mL of water and 1 drop of starch indicator, and it will appear blue-purple. (2) Take 10mL of this product, put it in a 50mL Erlenmeyer flask, cover the mouth of the bottle with a piece of filter paper moistened with starch indicator solution, leave it for 60s, and the blue color does not appear. Available iodine content: Titrated with sodium thiosulfate solution, the marked amount is in the range of 8.5% to 12.0%. The experimental design adopts two kinds of high temperature and low temperature. High temperature:...

Abstract

The invention belongs to the technical field of medicine preparation, and particularly relates to a 5% povidone-iodine solution for dairy cattle with strong stability and a preparation process thereof. The 5% povidone-iodine solution for dairy cattle with strong stability is characterized by comprising the components by weight percentage as follows: 5% of povidone-iodine, 1-5% of cosolvent, 1-5% of stabilizer, 1-10% of protective agent, 1-5% of antifreezing agent, 5-10% of surfactant, 5-20% of phosphate buffer and purified water. The preparation process comprises the steps of: processing materials; mixing; activating; filtering; adjusting pH values; setting volume; packaging; and sealing. The 5% povidone-iodine solution for dairy cattle with strong stability is used before or after milking the cattle to prevent mastitis of the dairy cattle. Meanwhile, nipples are prevented from being frozen and cracked, and the stability of the povidone-iodine solution at high and low temperatures is guaranteed.

Description

technical field [0001] The invention belongs to the field of medicine preparation, in particular to a highly stable 5% povidone-iodine solution for dairy cows and a preparation process thereof. [0002] Background technique [0003] Povidone-iodine is recognized as a new type of high-efficiency, broad-spectrum, less irritating, non-toxic and side effects, no residue, and no drug resistance fungicide. It has a strong killing effect on Staphylococcus aureus, Pseudomonas aeruginosa, hepatitis B virus, HIV, Trichomonas vaginalis, spores, etc., and can almost kill common bacteria in clinical practice. But so far, because povidone iodine has multiple iodine forms and is volatile, under different pH values, the content of available iodine varies greatly, which affects its content and directly affects the therapeutic effect. The pH value of povidone-iodine solution is very unstable, and the range of decline is very large. At present, povidone-iodine is mostly newly formulated for...
