SYNOPSIS: Clinically relevant doses of bactericidal antibiotics (quinolones, aminoglycosides and β-lactams) were shown to cause mitochondrial dysfunction and overproduction of reactive oxygen species in mammalian cells in vitro and in mice, leading to oxidative tissue damage. The antioxidant acetylcysteine prevented these effects.
