Safety and Efficacy Study of Oxazolidinones to Treat Uncomplicated Skin Infections

The purpose of this study is to assess the efficacy, safety and tolerability of RX-1741, an oxazolidinone, versus linezolid, another oxazolidinone, in the treatment of uncomplicated skin and skin structure infections
