Abstract

The invention provides roxithromycin composition freeze-dried orally disintegrating tablets and a preparation method of the orally disintegrating tablets, relates to the field of a medicine and a medicine preparation method technology and mainly solves the problems in the prior art that the oral preparation made by roxithromycin is not suitable for children, old people, bedridden patients, patients suffering from serious disability and the patients who are difficult to swallow. The roxithromycin composition freeze-dried orally disintegrating tablets are prepared from the following components by weight: 30-66% of roxithromycin, 33-66% of mannitol, 2-4% of gelatin, 0.1-0.15% of trichlorosucrose and 50-70% of tertiary butanol-water. The roxithromycin composition freeze-dried orally disintegrating tablets prepared by the above components are easy in preparation process, and simple in components, and mainly meet the administration requirements of children, old people, bedridden patients, patients suffering from serious disability and the patients who are difficult to swallow; moreover, the roxithromycin composition freeze-dried orally disintegrating tablets have the advantages of being fast to disintegrate, convenient to take, and good in taste; and the tablets take effect quickly and are fully absorbed, and the first pass effect of the liver is avoided.

Description

Technical field: [0001] The invention relates to the technical field of medicines and preparation methods of medicines, in particular to a freeze-dried orally disintegrating tablet of a roxithromycin composition and a preparation method thereof. Background technique: [0002] Roxithromycin is a white or off-white crystalline powder with a pH of 8.0-10.0. This product is a macrolide antibiotic, white or off-white crystalline powder, odorless, bitter, slightly hygroscopic. Soluble in ethanol, tert-butanol and acetone, dissolved in methanol and ether, almost insoluble in water; roxithromycin has a similar antibacterial spectrum to erythromycin, and is resistant to Staphylococcus aureus (except MRsA), Streptococcus (including Streptococcus pneumoniae and Streptococcus type A, B, C (except type G and Enterococcus), Corynebacterium, Listeria, Moraxella catarrhalis (catarrhalis), Legionella, etc. are highly sensitive or relatively sensitive. It also has a good antibacterial effec...
