RT Journal Article SR Electronic A1 Sinclair, Heather Q. T1 Therapeutic Augmentation for Treatment-Resistant MDD JF MD Conference Express YR 2009 FD SAGE Publications VO 9 IS 3 SP 24 OP 26 DO 10.1177/155989770903008 UL http://mdc.sagepub.com/content/9/3/24.abstract AB Major depressive disorder (MDD) affects about 15 million adults in the United States. Within that population, only one-third of patients who are treated with first-line antidepressant therapies achieve remission [Trivedi MH, Papakostas G, Perlis R. APA 2009]. Therefore, therapeutic augmentation, the addition of nonantidepressant compounds to an antidepressant regimen, may be a more reasonable option for those patients with first-line treatment resistance. This article explores the issue of treatment resistance in MDD and possible management strategies.
