MDL Number: MFCD01862248
Application: It was used as calibration standard at concentrations 3.90, 5.85, 7.80, 9.75 and 11.70 mg/mL during HPLC analysis to determine azithromycin in tablets and capsules.
Biochem Physiol Actions: Azithromycin dihydrate is a macrolide antibiotic, azalide subclass. It binds to the 50S subunit of the 70S bacterial ribosomes and inhibits RNA-dependent protein synthesis in bacterial cells. Azithromycin also has anti-immunomodulatory/anti-inflammatory properties, which make it useful in treating cystic fibrosis.
