[Use of azithromycin in ORL].

If the demonstration of the interest to treat beta-haemolytic streptococcal pharyngitis is not to be done, the recommended antibiotics, most of the time, display the drawback of a treatment with one to three intakes daily for 10 days. The azithromycin, with its numerous properties, allows for the required treatment duration, to decrease the intakes number, thus facilitating the compliance. Its in vitro activity is very good on streptococci with a MIC90 of 0.06 mg/l. Its in vivo activity in animal, with experimental Streptococcus pyogenes infection models is identical to the amoxicillin activity, and better than those of other tested macrolides. One of the major characteristics of azithromycin in man is its most peculiar pharmacokinetic with an extended half life and very high tonsillar concentrations, for at least 10 days after the administration of the product at the 1.5 g dose regimen over 3 days. In streptococcal acute tonsillitis clinical studies, with a 1.5 g dose regimen over 5 days, clinical results and bacterial eradication are identical to those obtained in the Penicillin V groups. This administration facility should greatly improve the treatment compliance and lower the risks of a prematurely discontinued treatment.
