Acetylspiramycin for spiramycin acetylated derivatives, belonging to 16 membered ring macrolide. It is suitable for sensitive Staphylococcus, Streptococcus and Streptococcus pneumoniae induced by mild to moderate infections, such as pharyngitis, tonsillitis, sinusitis, otitis media, periodontitis, acute bronchitis, chronic bronchitis, pneumonia, non-gonococcal urethritis, skin and soft tissue infection, can be used for the selection of drugs for cryptosporidiosis, or as a treatment for pregnancy women of toxoplasmosis. The mechanism for Acetylspiramycin combined with sensitive microbial 50S ribosomal subunit, RNA dependent inhibition of protein synthesis and bacteriostasis.

In Vivo Use Guide

Adult dosage: a 0.2 ~ 0.3g, 4 times a day, for the first time double. Pediatric dose each day according to the weight of 20 ~ 30 mg/kg, 4 times a day

Route of Administration: Oral

In Vitro Use Guide

Resident mouse peritoneal macrophages cultured with acetylspiramycin (ASPM) (25-100 micrograms/ml for 18 h) showed a 62-92% reduction in phagocytosis. This was due to decreases in both attachment and ingestion of SRBC and was additional to the detachment of some macrophages from the surface of the culture chamber. Morphologically the macrophages were vacuolated, with some nuclear condensation. When the cells were cultured for a further 48 h after removal of ASPM there was almost complete functional and morphological recovery.
