Prescribing of antidepressant treatment (ADT) for major depressive disorder (MDD) has increased in quantity and popularity over the last two decades. This is likely due to the approval of safer medications, better education of clinicians and their patients, direct-to-consumer marketing practices, and less stigma associated with those taking ADT. This trend has also been met with some controversy, however, as the ongoing safety and effectiveness of these treatments have at times been called into question. This paper discusses the differing levels of evidence that support the use of ADT based on (A) Food and Drug Administration approvals, (B) data from randomized controlled trials or meta-analyses and, where these are not available, the authors discuss and apply, (C) theoretical pharmacodynamic principles to justify antidepressant choice in the treatment of MDD patients. The final section discusses standard psychopharmacology guideline approaches to better alert the reader as to which practices are commonplace compared with those which are more outside of the standard of care.
Numerous clinical trials have been conducted to determine the utility of antidepressant treatment (ADT), psychotherapy, and combined psycho-pharmaco-psychotherapy (PPPT) in treating major depressive disorder (MDD). While all approaches have shown benefit over placebo to varying degrees, the parallel neurophysiological mechanisms that underlie their efficacy have received little attention. The authors will review and discuss a growing body of literature that relates the factors of treatment selection and response to the principles of neuromodulation, with emphasis regarding how neuroimaging and other experimental data reinforce the need for personalized MDD treatment. This manuscript and its theoretical approaches were supported by conducting relevant literature searches of MEDLINE and PubMed electronic databases, prioritizing systemic reviews, and randomized clinical trials using selected MeSH terms. The authors conclude that ADT, psychotherapy, and PPPT all create potentially observable neurofunctional changes and argue that additive and synergistic potentiation of these effects in PPPT may produce more sustained symptom relief than with monotherapy alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
