[Controlled multicentric study comparing cefixime and amoxicillin in the treatment of lower respiratory tract infections in adults].

This multicentre, randomized, double-blind study evaluated the effectiveness and safety of cefixime versus amoxicillin. Patients were admitted if they had lower respiratory tract infection with a bacterial pathogen susceptible to both study drugs. Diagnoses included acute respiratory tract infections with no underlying pulmonary pathology (cefixime 21, amoxicillin 27), acute exacerbation of chronic obstructive lung disease (cefixime 32, amoxicillin 42), superinfection of viral bronchitis or lung cancer, and pleuritis (cefixime 10, amoxicillin 6). Patients were treated for at least 10 days with either cefixime 200 mg b.d. or amoxicillin 1 g b.d. A clinical success rate of 80.7 per cent (50/62) in the cefixime group and 82.2 per cent (60/73) in the amoxicillin group was achieved in infections due to susceptible organisms. In acute infections with no underlying pathology, the clinical success rate was 90.5 per cent with cefixime and 81.5 per cent with amoxicillin. Twenty-three cefixime patients and 20 amoxicillin patients were seen 2 to 6 weeks after treatment: there were 2 and 1 clinical recurrences, respectively. All 3 patients were suffering from chronic obstructive lung disease. The bacteriological eradication rate at the end of treatment in assessable patients was 94.7 per cent (17/18) with cefixime and 80 per cent (16/20) with amoxicillin. Six and 11 new organisms appeared, responsible for 2 superinfections under cefixime and 7 under amoxicillin. Treatment was well tolerated by 96.4 per cent of cefixime patients and 90 per cent of amoxicillin patients. This study confirms the value of cefixime as a new oral antibiotic in the treatment of lower respiratory tract infections in adults.
