At an estimated cost of almost $50 billion a year, the socioeconomic burden
of major depressive disorder is enormous. Although remission has been iden
tified as the key goal of treatment, such treatment must be highly acceptab
le to patients, predictably effective, and carry minimal adverse effects. T
he cornerstone of depression management, remission can improve clinical sta
tus, functional ability, and quality of life for the patient while lowering
utilization costs related to the disease and its comorbidities. Initially,
the goals of therapy are to: (1) reduce and ultimately remove all signs an
d symptoms of the depressive syndrome; (2) restore occupational and psychos
ocial function to the asymptomatic state; and (3) achieve and maintain remi
ssion. Most patients can achieve these goals with the help of antidepressan
t medications, problem-focused psychotherapy, or a combination of the 2 met
hods. Following an initial assessment of the patient, treatment of depressi
on has 3 phases: acute, continuation, and maintenance. Although adherence t
o treatment is crucial to successful treatment of depression, only about 25
% to 35% of patients will achieve remission after 6 to 8 weeks of treatment
; another 15% to 20% may remain depressed for months or years. Patients who
achieve remission are much less likely to relapse than those who do not. M
uch debate has focused on the relative merits of prescribing selective sero
tonin reuptake inhibitors or venlafaxine. Results of a pooled analysis of 8
such comparative studies are presented.
