Cefpodoxime proxetil in upper respiratory tract infections.
Cefpodoxime proxetil is a new third generation oral cephalosporin, which shows potent antibacterial activity against both Gram-positive and Gram-negative bacteria, and high stability in the presence of beta-lactamases. Low concentrations of cefpodoxime inhibit most respiratory pathogens, including Haemophilus influenzae, Streptococcus pneumoniae, and Moraxella (Branhamella) catarrhalis. Cefpodoxime reaches concentrations of 0.24 +/- 0.06 mg/kg in tonsils, 0.89 +/- 0.80 mg/kg in lung parenchyma, and 0.91 +/- 0.01 mg/kg in bronchial mucosa; these values exceed by far the minimum inhibitory concentrations (MICs) of cefpodoxime for respiratory pathogens. Preliminary clinical studies were carried out in 181 patients with upper respiratory tract infections: the results indicated an overall clinical response in 88.4% of patients; in 30% the clinical efficacy was excellent and in 58.5% it was good. Further studies showed clinical cure in 90.3% of patients with pharyngotonsillitis, and clinical efficacy (cure plus improvement) in 95% of those with acute sinusitis. Moreover, bacterial eradication was obtained in 78 to 96.7% of cases, most of which involved H. influenzae, streptococci, or M. catarrhalis. Cefpodoxime appears to be an effective new antibacterial that can be recommended as a drug of first choice in the treatment of most upper respiratory tract infections.[1]References
