    Abstract:
    Cefdinir, an oral cephalosporin active against Streptococcus pyogenes (group A beta-hemolytic streptococci [GABHS]), is also resistant to degradation by most oropharyngeal beta-lactamases. This multicenter, randomized, controlled, double-masked study assessed the tolerability and efficacy of 2 dosing regimens of cefdinir in the treatment of pharyngitis due to GABHS. Adults and adolescents with pharyngitis due to GABHS received cefdinir 600 mg QD, cefdinir 300 mg BID, or penicillin V 250 mg QID each for 10 days. A throat culture and clinical assessment were obtained 4 to 9 days after completion of therapy. Of 919 patients enrolled, 644 (70.1%) were microbiologically assessable. The eradication rates 4 to 9 days after completion of therapy were 91.4% in the cefdinir QD group, 91.7% in the cefdinir BID group, and 83.4% in the penicillin group (P = 0.02 for cefdinir QD vs penicillin, P = 0.01 for cefdinir BID vs penicillin, P = 0.95 for cefdinir QD vs cefdinir BID). Clinical cure rates were also superior with cefdinir QD (94.8%, P = 0.02) and cefdinir BID (96.3%, P < 0.01) compared with penicillin (88.9%). Diarrhea was more common in the cefdinir groups (P < 0.001). Seventeen cefdinir patients and 4 penicillin patients discontinued therapy because of adverse reaction (P = 0.13). Ten days of treatment for streptococcal pharyngitis with cefdinir QD or BID is superior to treatment with penicillin V for the eradication of GABHS from the pharynx, although it is associated with a higher rate of adverse reactions.
