Answer

Although some necrotizing infections may still be susceptible to penicillin, clindamycin is the treatment of choice for necrotizing infections, for the following reasons [62] :

  • Unlike penicillin, the efficacy of clindamycin is not affected by the inoculum size or stage of bacterial growth [89, 90]

  • Clindamycin is a potent suppressor of bacterial toxin synthesis [91, 92]

  • Subinhibitory concentrations of clindamycin facilitate the phagocytosis of GABS [53]

  • Clindamycin reduces the synthesis of penicillin-binding protein, which, in addition to being a target for penicillin, is also an enzyme involved in cell wall synthesis and degradation [90]

  • Clindamycin has a longer postantibiotic effect than β-lactins such as penicillin [92]

  • Clindamycin suppresses lipopolysaccharide-induced mononuclear synthesis of tumor necrosis factor-α (TNF-α) [93]

Consequently, the success of clindamycin also may be related to its ability to modulate the immune response. [94]
