Administration Dosage Frequency Description References
Mice Lethal S. pneumoniae lung infection model Oral 12 mg/kg Twice daily for 3 days Evaluated efficacy against wild-type and GrlA mutant infections. Despite mutant MIC increase (0.5 μg/ml), PD50 only rose 1.9-fold (11.1 mg/kg vs 6.0 mg/kg). Drug levels exceeded MIC in lungs for >20 hours. Antimicrob Agents Chemother. 1996 Dec;40(12):2691-7
Swiss mice Immunocompetent mice (penicillin-susceptible strain P-4241) and leukopenic mice (penicillin-resistant strains P-54988, P-12698, P-15986 and ciprofloxacin-resistant strain P-18316) Subcutaneous injection 12.5-300 mg/kg Every 8 or 12 hours for 3 days Evaluate the in vivo efficacy of Trovafloxacin in a mouse pneumonia model against penicillin-susceptible and -resistant S. pneumoniae. Results showed that Trovafloxacin (25 mg/kg) provided 2- to 4-fold higher survival rates than sparfloxacin (50 mg/kg) or temafloxacin (50 mg/kg) and 8- to 16-fold higher than ciprofloxacin (100 mg/kg) against penicillin-susceptible and -resistant strains. The AUC/MIC ratios in serum and lung tissue were more favorable with trovafloxacin than with other quinolones. Antimicrob Agents Chemother. 1998 Apr;42(4):862-7
