The usual adult starting dosage for oral use is 37.5 mg of venlafaxine once daily, which is increased to 75 mg once daily after a meal from 1 week later.
The dose may be adjusted within a range not exceeding 225 mg/day according to the patient's age and symptoms.

Change From Baseline in the 17-item Hamilton Rating Scale for Depression (HAM-D17) Total Scores at Pre-specified Evaluation Points
Time Frame: 12 weeks from the start date ( up until 52 weeks)
|
HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with depression (symptoms such as depressed mood, work and activities, sleep, suicide, psychomotor agitation/retardation, appetite, sexual interest, anxiety, and somatic symptoms).
The items of the HAM-D17 are rated on a scale of 0 to 2 (8 items) or from 0 to 4 (9 items), and the total score ranges from 0 to 52, higher scores indicating more severity.
Change from baseline: mean score at observation minus mean score at baseline.
Evaluation was performed at Week 4, 8, 12, 16, 24, 36, and 52.

12 weeks from the start date ( up until 52 weeks)

Change From Baseline in the Montgomery - Asberg Depression Rating Scale (MADRS) Total Scores at Pre-specified Evaluation Points
Time Frame: 12 weeks from the start date ( up until 52 weeks)
|
MADRS is a clinician-administered rating scale that assesses the overall severity of depressive symptoms.
The MADRS had a 10-item checklist (apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts).
Items are scored from 0 to 6, and the total score ranges from 0 to 60, higher scores indicating more severity.
Change from baseline: mean score at observation minus mean score at baseline.
Evaluation was performed at Week 4, 8, 12, 16, 24, 36, and 52.

12 weeks from the start date ( up until 52 weeks)

Clinical Global Impressions-Severity
Time Frame: 12 weeks from the start date (up until 52 weeks)
|
CGI-S is a 7-point clinician-administered rating scale that assesses overall severity of the current illness state.
The score ranges from 1 to 7, higher scores indicating more affected: "1: normal, not at all ill," "2: borderline mentally ill," "3: mildly ill," "4: moderately ill," "5: markedly ill," "6: severely ill," or "7: among the most extremely ill patients."
Evaluation was performed at Week 4, 8, 12, 16, 24, 36, and 52.
|
12 weeks from the start date (up until 52 weeks)

Changes in the Clinical Global Impressions-Improvement
Time Frame: 12 weeks from the start date (up until 52 weeks)
|
CGI-I is a 7-point clinician-administered rating scale that assesses overall improvement of the disease/condition.
The score ranges from 1 to 7, higher scores indicating more affected: was assessed as "1: markedly improved," "2: moderately improved," "3: mildly improved," "4: no change," "5: slightly worsened," "6: worsened," or "7: severely worsened."
Evaluation was performed at Week 4, 8, 12, 16, 24, 36, and 52.
