Said Roxithromycin composition freeze-drying oral cavity disintegration tablet specification is 150mg/ sheet, 250mg/ sheet or 300mg.
We have formulated relevant detection method to the disintegration rate of Roxithromycin composition freeze-drying oral cavity disintegration tablet:
Disintegration
According to inspection technique disintegration (two appendix ⅹ of Chinese Pharmacopoeia version in 2010 A); The stainless steel shaft of hanging basket through the upper end hung on the metal rack; Immerse in the 1000ml beaker; And screen cloth fills temperature and is 37 ℃ ± 1 ℃ water apart from beaker bottom 25mm in the beaker when regulating the hanging basket position it being descended, when regulating height of water level hanging basket being risen screen cloth in the underwater 15mm place.
