Azithromycin in children: A critical review of the evidence

Background: Azithromycin is a macrolide antibiotic that can be dosed once daily. In the last decade, the body of literature concerning the clinical applications of azithromycin has grown rapidly, leading to improved understanding as well as new questions about the role of this drug in the treatment of adult and pediatric infections. Objective: This review explores the use of azithromycin in the treatment of pediatric infections. Methods: We conducted a MEDLINE literature search to identify pertinent English-language studies of azithromycin published between 1987 and 2001. Results: The use of azithromycin in the treatment of acute Streptococcus pyogenes pharyngotonsillitis, acute otitis media, community-acquired pneumonia, pertussis, skin and soft tissue infections, Mycobacterium avium complex (MAC), trachoma, typhoid fever, cat-scratch disease, cryptosporidiosis, and legionnaires' disease has been studied in clinical trials. Conclusions: Azithromycin is indicated as a first-line treatment for respiratory tract infections caused by Legionella species, Mycoplasma pneumoniae, and Chlamydia pneumoniae, and as empiric therapy for community acquired pneumonia in older children and adolescents who are deemed appropriate for outpatient oral therapy. Azithromycin in a single dose is an excellent treatment for chlamydia cervicitis/urethritis and for trachoma and has demonstrated efficacy in prophylaxis and treatment of disseminated MAC infections in children who have AIDS. Azithromycin may be considered as an alternative in the treatment of skin and soft tissue infections, although local patterns of resistance of pathogens must be considered in its selection.
