Abstract
The invention belongs to the novel technology field of the medicines and relates to a novel dosage form of ceftibuten for treating: upper respiratory tract infection such as pharyngitis, antiaditis, scarlet fever, paranasal sinusitis, and otitis medium; lower respiratory tract infection such as acute bronchitis, acute attack of chronic bronchitis and pneumonia; urinary tract infection; enteritis and gastroenteritis. The dosage form is characterized in that the dosage form is dispersing tablets, and can disintegrate quickly into fine granules when encountering water, and the granules uniformly disperse and can pass through size 2 sieve (24 mesh). Preparing the medicines with small dose and low water-solubility into the dispersing tablets can obviously improve absorption in vivo and improve bioavailability.
Description
technical field [0001] The invention belongs to the field of new medicine technology, and relates to a new dosage form of ceftibuten, which is used for treating upper respiratory tract infections such as pharyngitis, tonsillitis, scarlet fever, paranasal sinusitis and otitis media; lower respiratory tract infections such as acute bronchitis and acute chronic bronchitis seizures, pneumonia; urinary tract infection; enteritis and gastroenteritis. Specifically, it is a preparation method and application of ceftibuten dispersible tablets. Background technique [0002] Cephalosporin antibiotics have the characteristics of broad antibacterial spectrum, strong antibacterial activity, high curative effect, and low toxicity, and have been widely used clinically. By 1998, 56 varieties including the first generation to the fourth generation were on the market in the world. Since the first-generation cephalosporin cephalothin was successfully developed in China in the 1970s, cephalospo...
