[Depyrogenation in key manufacturing processes of Reduning injection].

Objective: To investigate the effect of removing bacterial endotoxin in the key processes of Reduning injection.
Method: The content of bacterial endotoxins was detected by kenitic-turbidimetry and the removal efficacy was studied before and after using 0.8% of activated carbon and ultrafiltration with molecular weight cut-off of 10 x 10(3).
Result: The adsorption rate of bacterial endotoxins was 78.7% by using activated carbon, while the removal efficacy of bacterial endotoxins was 99.6% with ultrafiltration membrane at cut-off molecular weight 10 x 10(3).
Conclusion: The key technology can effectively guarantee the safety of Reduning injection.
