title: Postantibiotic effects of telavancin against 16 gram-positive organisms.
abstract: The in vitro postantibiotic effects (PAEs), postantibiotic sub-MIC effects (PA-SMEs), and sub-MIC effects of telavancin were determined for 16 gram-positive organisms. Telavancin staphylococcal, streptococcal, and enterococcal PAE ranges were 0.9 to 3.9 h, 0.4 to 6.7 h, and 0.3 to 2.2 h, respectively. The PA-SME ranges (0.4 times the MIC) for staphylococci, streptococci, and enterococci were 6.7 to >10.7 h, >10.7 to >11.0 h, and >10 to >10.8 h, respectively. The extended PAE of telavancin, together with its long elimination half-life in humans, supports once-daily dosing for this investigational drug.
