Efficacy and safety of temafloxacin versus those of amoxicillin in hospitalized adults with community-acquired pneumonia

Abstract

Temafloxacin, a new fluoroquinolone, was compared with amoxicillin in the treatment of adult hospitalized patients with community-acquired pneumonia. In this double-blind, multicenter study, patients were randomly assigned to treatment with temafloxacin at 600 mg twice daily (n = 125) or amoxicillin at 500 mg three times daily (n = 121); the average duration of treatment was 10 days. Clinical recovery rates were similar for patients treated with temafloxacin and amoxicillin (89 and 85%), as were bacterial eradication rates (99 and 97%). This was also true for subgroups of patients with pneumococcal pneumonia (n = 100), nonpneumococcal pneumonia (n = 122), or atypical pneumonia (n = 12). Outcomes for temafloxacin- and amoxicillin-treated patients were also similar in terms of defervescence, improvement in leukocytosis, and radiographic evidence of infection. The frequency and severity of adverse events were similar in both groups, consisting primarily of digestive disorders and skin manifestations. We conclude that temafloxacin may be recommended as an alternative antibacterial drug for patients with suspected pneumococcal pneumonia who fail to respond to benzylpenicillin or amoxicillin when the incidence of multiresistant pneumococcal strains is low. In countries where the incidence of these strains is high, temafloxacin may also be recommended.
