Product Features
Sitafloxacin API adopts new-generation synthesis and purification technology, breaking through the purity bottleneck of traditional quinolone drugs. Its major component content is stably above 99.0%, and the impurity level is far lower than the pharmacopoeia limit, fully complying with pharmaceutical-grade API standards and ensuring the safety and effectiveness of preparations from the source. The product has a broad antibacterial spectrum and strong bactericidal ability, causing potent inhibition on key clinical pathogens such as Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Klebsiella, Pseudomonas aeruginosa, as well as atypical pathogens such as Mycoplasma and Chlamydia.
It has a low cross-resistance rate with other antibacterial drugs and can be used as a first-line raw material for the treatment of multi-drug resistant bacterial infections. Sitafloxacin Powder has stable physical and chemical properties and low hygroscopicity . It is compatible with mainstream preparation processes such as dry granulation, wet granulation and sterile filling, effectively improving production efficiency and the stability of final products. As a highly active Sitafloxacin API, the product is rapidly absorbed in vivo with high bioavailability and wide tissue distribution. It reaches a high concentration in infected target organs with a long-lasting effect, quickly controlling infection symptoms and shortening the treatment cycle, making it a core raw material for high-end antibacterial preparations.
