Brief Summary:

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 or disease Intervention/treatment Phase
Major Depressive Disorder Drug: escitalopram Phase 4

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.
