Biological Activity

Description	Azithromycin Dihydrate(CP-62993 dihydrate) is an acid stable orally administered macrolide antimicrobial drug, structurally related to erythromycin.

In vitro
In vitro	Azithromycin displays a similar spectrum of antimicrobial activity. Azithromycin is marginally less active than erythromycin in vitro against Gram-positive organisms, although this is of doubtful clinical significance as susceptibility concentration fall within the range of achievable tissue Azithromycin concentrations. The mean MIC90 of Azithromycin against erythromycin susceptible/βL-ve strains, Streptococcus strains and NS (not selected for antimicrobial sesitivity)/erythromycin susceptible strains is 0.63, 0.35, and <0.27 mg/L, respectively. In contrast, Azithromycin appears to be more active than erythromycin against many Gram-negative pathogens and several other pathogens, notably Haemophilus influenza (MIC90, 1.34 mg/L), H. parainfluenzae(MIC90, 1 mg/L), Moraxella catarrhalis (MIC90, <0.1 mg/L), Neisseria gonorrhoeae (MIC90, 0.25 mg/L), Ureaplasma urealyticum, Bordetella spp (MIC90, 0.03-0.24 mg/L) and Borrelia burgdorferi. Azithromycin is also activity against clinical isolates of anaerobic bacteria Gram-positive cocci and propionibacterium acnes with MIC90 of 2.3, 0.03 mg/L. Like erythromycin and other macromycin, the activity of Azithromycin is unaffected by the production of β-lactamase. However, erythromycin-resistant organisms are also resistant to Azithromycin. ^[1]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
