Abstract

A child cefdinir composition freeze-dried oral disintegrating tablet and a preparation method thereof relate to the technical field of medicine and preparation methods for medicine. The child cefdinir composition comprises, by weight, 24% to 49% of cefdinir, 49% to 72% of mannitol, 2% to 4% of gelatin and 0.1% to o.15% of sucralose. A tert butyl alcohol- water cosolvent is used as a menstruum. The freeze-dried oral disintegrating tablet has the advantages that components are simple, water is not required when a user takes the freeze-dried oral disintegrating tablet, chewing is not required, disintegrating time in human mouths is no more than two seconds, absorption is quick, bioavailability is high, intestinal canal residue is few, side effect is low, hepatic first pass effect is small, and the freeze-dried oral disintegrating tablet tastes good and is particularly suitable for infant patients.

Description
