Effexor® XR

Drug

150 mg Extended-Release Capsule

Other names: Venlafaxine Hydrochloride (generic name)

Primary outcomes

  1. Cmax of Venlafaxine.

    Time frame: Blood samples collected over a 36 hour period.

    Bioequivalence based on Venlafaxine Cmax (maximum observed concentration of drug substance in plasma).

  2. AUC0-t of Venlafaxine.

    Time frame: Blood samples collected over a 36 hour period.

    Bioequivalence based on Venlafaxine AUC0-t (area under the concentration-time curve from time zero to time of last measurable concentration).

  3. AUC0-inf of Venlafaxine.

    Time frame: Blood samples collected over a 36 hour period.

    Bioequivalence based on Venlafaxine AUC0-inf (area under the concentration-time curve from time zero to infinity).

Secondary outcomes

  1. Cmax of O-Desmethylvenlafaxine.

    Time frame: Blood samples collected over a 36 hour period.

    Informational comparison of Cmax values for the metabolite O-Desmethylvenlafaxine.

  2. AUC0-t of O-Desmethylvenlafaxine.

    Time frame: Blood samples collected over a 36 hour period.

    Informational comparison of AUC0-t values for the metabolite O-Desmethylvenlafaxine.

  3. AUC0-inf of O-Desmethylvenlafaxine.

    Time frame: Blood samples collected over a 36 hour period.

    Informational comparison of AUC0-inf values for the metabolite O-Desmethylvenlafaxine.
