Cohorts and Interventions

Group / Cohort
Intervention / Treatment
venlafaxine
Patients with no experience of using time Effexor(venlafaxine) who will be administered time Effexor(venlafaxine)for the first
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. However, the dose should be increased by 75 mg/day at intervals of not less than 1 week.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Adverse Drug Reactions
Time Frame: 12 weeks from the start date (up until 52 weeks)
An adverse drug reaction (ADR) was any untoward medical occurrence attributed to Effexor in a participant who received Effexor. A serious ADR was a ADR resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening experience (immediate risk of dying); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly. Relatedness to Effexor was assessed by the physician.
12 weeks from the start date (up until 52 weeks)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
12 weeks from the start date (up until 52 weeks)
