Preparation and Quality Investigation of Azithromycin Dispersible Tablets

Objective: To experiment on the preparation of dispersible azithromycin tablets.Methods With the dispersible time as the focus of attention,different disintegrants were compared and orthogonal design was compared with that of the conventional tablets in the market.Results The result showd that its disintegration and uniformity of dispersion reached the standard of Ch.P. 2000,and its quality was stable.Of the four tested disintergrants crospovidone had the best dispersing effect and the dispersible tablets of optimal formulation exhibited a disintegrants crospovidone had the best dispersing effect and the dispersible tablets of optimal formulation exhibited a disintegrating time of 92.1s with a much quicker dissolution speed than that of the conventional tablets.Conclusion The dispersible Agithromycin tablets have a higher dissolution speed than those of conventional tablet.
