Last verified: January 2010

This will be an open label study of escitalopram. Patients not responsive to citalopram will be switched directly to escitalopram.

Patients will receive escalating doses of escitalopram up to a maximum of 50 mg until they either achieve remission (MADRS <9) or fail to tolerate the dose.

Condition Intervention Phase
Major Depressive Disorder Drug: escitalopram Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Primary Outcome Measures:
  • The number of patients achieving remission (MADRS<9). [ Time Frame: 8 months ]

Enrollment: 60
Study Start Date: October 2008
Study Completion Date: December 2009
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Active
Active escitalopram
Drug: escitalopram
Dose ranging up to 50mg

Detailed Description:

Patients will receive escalating doses of escitalopram up to a maximum of 50 mg until they either achieve remission (MADRS <9) or fail to tolerate the dose.

Visit 1 - (Initial visit) - escitalopram 10 mg Visit 2 - (Week 2) - escitalopram 20 mg Visit 3 - (Week 4) - review visit Visit 4 - (Week 6) - MADRS <12 - continue 20 mg MADRS >12 - escitalopram 30 mg Visit 5 - (Week 8) - MADRS <8 - continue current dose MADRS >8 - escalate dose (20 mg to 30 mg or 30 mg to 35mg)

Thereafter, Patients who have achieved remission will be maintained on the remission dosage and reviewed at four weekly intervals. At any subsequent visit where the MADRS is >8 they will have a dosage increase

Patients who have not achieved remission will have dosage escalated by 5 mg at two weekly intervals until remission, a maximum dose of 50 mg is achieved or the dosage is intolerable when they will be reduced to the previous tolerable dose.

Patients will be followed up until eight months from their initial visit.
