    7. any other drug with potential psychotropic effects within the last week.
    8. any drug known to lower blood pressure in the last week.
  6. The patient has been treated with any investigational product within 3 months prior to screening.
  7. The patient has been treated during the current episode with escitalopram or venlafaxine.
  8. The patient has a history of severe drug allergy or hypersensitivity, or known hypersensitivity to escitalopram or venlafaxine.
  9. The patient started (or will start) formal psychotherapy in the month preceding inclusion.
  10. The patient has a previous history of convulsive disorder other than a single childhood febrile seizure.
  11. The patient presents evidence of urinary retention or glaucoma.

  13. The patient has, in the opinion of the investigator, on the basis of a physical examination, medical history and vital signs, a comorbid conditions(s) that would render inclusion in the study unsafe.
  14. The patient takes medication that, in the opinion of the investigator, could interfere with the assessments of safety, tolerability, or efficacy.
  15. The patient, in the opinion of the investigator, is unlikely to comply with the clinical study protocol or is unsuitable for any reason
