Evaluation of short-term clinical efficacy of 3-day therapy with azithromycin in comparison with 5-day cefcapene-pivoxyl for acute streptococcal tonsillopharyngitis in primary care

Abstract

Group A streptococcal (GAS) tonsillopharyngitis is one of the few conditions for which antibiotics are advocated among common upper respiratory infections. Although a 3-day course of azithromycin is attracting attention as a treatment of choice for the condition, it is not clear if the efficacy of the treatment is comparable with that of treatment with cephalosporins. A prospective, randomized, comparative multicenter study was conducted to compare the efficacy of azithromycin (AZM) given once daily for 3days with that of cefcapene-pivoxyl (CFPN-PI) divided into three daily doses for 5days. 88 patients (male: 38, mean age: 16.5) were treated with AZM and 69 (male: 34, mean age: 16.9) with CFPN-PI. The symptoms of all but 5 (2 for AZM and 3 for CFPN-PI) of the patients were resolved by the 8th day of the treatment. By the 4th day of the treatment, criteria for clinical efficacy were fulfilled in 71 (80.7%) subjects who were treated with AZM and in 48 (67.6%) of those treated with CFPN-PI (p=0.07). The same figures on the 8th day of the treatment were 86 (97.7%) and 68 (95.8%), respectively (p=0.66), confirming there was no significant difference in clinical efficacy between the two treatments. Mild adverse reactions were reported by two patients treated with AZM and by none treated with CFPN-PI. The clinical efficacy of a 3-day course with AZM was comparable with that of a 5-day course of CFPN-PI for GAS tonsillopharyngitis.
