    Abstract:
    OBJECTIVE: To evaluate the clinical effects, pharmacokinetics, post-antibiotic effect (PAE) and toxicity of netilmicin as a single daily dose in the treatment of lower respiratory tract infection. METHODS: 48 cases were divided into 3 groups: In the first group, Netilmicin(6 mg.kg-1.d-1) was administered in a single daily dose; in the second group, netilmicin (200 mg/d) was combined with cefazolin (3 g, Q12 h); and in the third control group, the combination of cefazolin and Amikacin was used. Pharmacokinetics were studied in 7 patients using the TDX system, and PAE induced by Netilmicin was determined by the Avantage microbiologic system. Clinical symptoms, laboratory studies, chest X-rays, and side effects were observed. RESULTS: The overall clinical effects of the first group were better than those of the third group. The mean serum concentration of netilmicin was 27.23 mg/L, the valley serum concentration was 0.23 mg/L, T1/2 beta was 5.059 h, AUC was 70 micrograms.h-1.ml-1.netilmicin at concentrations 0.5, 1.0 and 4 times the MIC showed different degrees of PAE against 4 strains of bacterium. Nephrotoxicity and ototoxicity were not found in the treatment group. CONCLUSIONS: Netilmicin in a single daily dose resulted in a high peak serum concentration and big AUC. As a concentration-dependent bactericidal agent, netilmicin showed a longer PAE and better therapeutic effects.
