Spiramycin API powder Introduction
Spiramycin API powder is a raw material for macrolide antibiotics, which appears as a white or slightly yellow crystalline powder with slight hygroscopicity and is easily soluble in organic solvents. The product is prepared using microbial fermentation technology and undergoes strict purification and refinement. Its purity meets the mainstream pharmacopoeia standards of CP/USP/BP/EP, and indicators such as heavy metals and microbial limits meet the requirements of pharmaceutical and veterinary medicine. It exerts antibacterial effects by inhibiting bacterial protein synthesis and has good inhibitory activity against Gram positive bacteria, some negative bacteria, mycoplasma, chlamydia, and Toxoplasma gondii. It has the characteristics of wide antibacterial spectrum, strong tissue penetration, low side effects, and low drug resistance. Our Spiramycin has stable and reliable quality, and is a core raw material for the preparation of oral and veterinary drug formulations, as well as for foreign trade exports. It is widely used in fields such as medicine and animal husbandry.
