Abstract

The present invention provides a tilmicosin dry suspension. The invention also provides a method for preparing the dry suspension and uses thereof. According to the tilmicosin dry suspension of the present invention, via reasonable compatibility of excipients, dispersion of tilmicosin in water is significantly improved, so the tilmicosin is enabled to be evenly distributed in the water in a long time, convenient for clinical administration of medicine by drinking water. Meanwhile, the dry suspension has greatly improved the palatability of the tilmicosin, so the dry suspension can be used not only for animal groups with underdeveloped taste such as chickens, but also for other animal groups with sensitive taste such as pigs, thus expanding the scope of application of the product.

Description

technical field [0001] The invention relates to a tilmicosin dry suspension, a preparation method and application thereof. Background technique [0002] Tilmicosin (Tilmicosin) is a semi-synthetic macrolide antibiotic for livestock and poultry, with a chemical name of 4 A -O-de(2,6-dideoxy-3-C-methyl-L-ribose-pyranylhexyl)-20-deoxy-20-(3,5-dimethyl-1-piperidinyl)- Tylosin, also known as 20-deoxy-20-(3,5-dimethyl-1-piperidinyl) decarbamucose tylosin, its structural formula is: [0003] [0004] Molecular formula is C 46 h 80 N 2 o 13 , molecular weight 869.13. [0005] The tilmicosin products recorded in "The Veterinary Pharmacopoeia of the People's Republic of China (2010 Edition)" have three dosage forms: premix, injection, and solution, and are mainly used clinically to treat animals such as cattle, goats, sheep, dairy cows, pigs, and chickens. Infectious diseases caused by sensitive bacteria, especially livestock and poultry respiratory infection and cow mastiti...
