An in vitro study was carried out to investigate the effect of clarithromycin, a new oral macrolide, on neutrophil reactive oxygen species generation and chemotaxis. It was found that neutrophil-generated O2-, H2O2 and OH. levels were significantly increased by clarithromycin at concentrations of 50 μg/ml (P < 0.05). The drug also significantly increased chemotaxis (P < 0.05). These results indicate that clarithromycin may enhance the activation of neutrophils in vivo.
