The efficacy, tolerability and safety of azithromycin and co-amoxiclav in the treatment of non-severe acute maxillary/ethmoidal sinusitis were compared in a randomized, open clinical trial in 254 adult patients. The predominant pathogens were Streptococcus pneumoniae and Haemophilus influenzae (83 patients). Azithromycin was administered orally to 165 patients at a single daily dose of 500 mg for 3 days, and co-amoxiclav (4:1) to 89 patients, at a dose of 500 mg three times daily for 10 days. The overall clinical response rates were 87.5% for azithromycin and 83.7% for co-amoxiclav at follow-up (day 21-28). Microbiological responses to both drugs were good, with only five patients in each group having a persistent infection after treatment. Both drugs were well tolerated and produced similar incidences of adverse events, which were mostly gastrointestinal. Azithromycin was as effective, and as well tolerated as co-amoxiclav, and its shorter simpler dosing regime may offer advantages in compliance and cost.
