Population: Evaluable population. The evaluable population are those subjects with calculable values for one or more of AUC0-inf (AUC0-t when appropriate) and/or Cmax.

The AUC(0-32) and AUC(inf) of (-/+)-M1 after each treatment (i.e., 10, 20 and 30 mg desmetramadol fasted, and 30 mg desmetramadol fed)

SECONDARY outcome

Timeframe: Participant report adverse events throughout study enrolment; investigators observe adverse events during all 11 days of inpatient treatment; laboratory safety labs are obtained on Day 11 (the final study day).

Population: Only treatment-emergent AEs (TEAEs) are summarized. A TEAE is defined as an AE that is starting or worsening at the time of or after study drug dosing. Each TEAE will be attributed to a treatment based on the onset date and time of the AE. An AE that occurs during the washout period between drugs will be considered treatment-emergent to the last drug administered prior to onset of the AE. See "Adverse Events" for data table.

Adverse events will include: 1) reports by participants; 2) observations by investigators; and 3) abnormal laboratory safety test results.
