RESUMEN
Objective To establish a suitable formulation for the dispersible tablets of breviscapinum. Methods The preparative process was scanned out by single factor test and orthogonal design. A comprehensive scoring analysis was performed with disintegrating time and rigidity as the indexes. Results The demonstration for the dispersible tablets from the optimized formulation,being totally disintegrated within three minutes and sifted through the sieve in size of the 2nd,show better dissolubility in-vitro in comparison with the common tablets and their quality meets with the requirement for the dispersible in Phamarcopoeia of the People's Republic of China. Conclusion The formulation screened out for the dispersible tablets of breviscapinum is suitable for the production on a large scale.
RESUMEN
AIM:The different factors on stability of salvianolic acid B in Danshen freeze-dried powder injection was investigated to provide the experimental data for clinical application and storage of the preparation. METHODS: The stability of salvianolic acid B for lamplight,temperature,sodium chloride injection and glucose injection in Danshen freeze-dried powder injection were studied and the content of salvianolic acid B was determined by HPLC. RESULTS: The content of salvianolic acid B in Danshen freeze-dried powder injection didn't almost change under the condition of lamplight(3000lx) in 60 d.Its expiry date estimated by Q_(10) method was(2.39) a.The preparation was matched respectively with(0.9%) sodium chloride injection and 5% glucose injection,the content of salvianolic acid B was invariable and insoluble particles were qualified under the condition of 25 and 37 ℃ in 24 h. CONCLUSION: Danshen freeze-dried powder injection is stable for lamplight and clinical injection and the expiry data of the preparation is(2.39) a.
