Summary:

      The purpose of this study is to evaluate the efficacy and safety of MDT-10013 in men and
      women 18 to 80 years of age who are undergoing bunionectomy. The primary objective is to

             screening ECG.

             clinically significant laboratory values that, in the opinion of the investigator,
             could compromise the safety of the subject or the scientific integrity of the study

         21. Is judged by the investigator not to be a suitable candidate for study treatment and

         22. Is not stabilized on the following medications for at least 8 weeks prior to dosing:
             selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake
