The efficacy of an investigational macrolide, azithromycin, in the treatment of acute otitis media consequent to an infection by a strain of beta-lactamase-producing Haemophilus influenzae, was evaluated using the chinchilla animal model. The results indicate that the azithromycin high-dosage (30 mg/kg/d) group has a significantly higher rate for effusion sterilization and resolution as compared with the other treatment groups. Unique pharmacokinetic properties of this investigational antimicrobial were demonstrated. Clinical trials using azithromycin for the treatment of upper respiratory tract infections, including otitis media, are warranted.

D004917 Erythromycin A bacteriostatic antibiotic macrolide produced by Streptomyces erythreus. Erythromycin A is considered its major active component. In sensitive organisms, it inhibits protein synthesis by binding to 50S ribosomal subunits. This binding process inhibits peptidyl transferase activity and interferes with translocation of amino acids during translation and assembly of proteins.
