It was shown to be more effective against certain Gram-negative bacteria, particularly Legionella pneumophila. Roxithromycin exerts its antibacterial action by binding to the bacterial ribosome and interfering with bacterial protein synthesis. It is marketed in Australia as a treatment for respiratory tract, urinary and soft tissue infections."}]
