[Antibiotic strategy in bronchial infections. Role of roxithromycin].

Data in the literature on roxithromycin treatment in respiratory tract infections demonstrate to clinical and bacteriological efficacy at high doses comparable with other available antibiotics. ANTIBIOTIC STRATEGY: These results are explained by the bioavailability of roxithromycin, its antibacterial spectrum, and its pharmacokinetic features (high serum peak, high intracellular and extracellular concentrations).
