Pharmacological management of treatment-resistant depression

New drugs, old problems: Revisiting… Pharmacological management of treatment-resistant depression

Effective pharmacological management of depression resistant to antidepressant medication is best carried out in the context of a supportive and collaborative relationship, following a mutually agreed care plan. Simpler pharmacological approaches such as switching antidepressant classes are tried first, then augmentation is used if needed. New classes of antidepressants have made antidepressant combination a popular augmentation strategy, but lithium addition has most supporting evidence. The use of atypical antipsychotics as augmenting agents is increasing. For patients unresponsive to these strategies, monoamine oxidase inhibitors and electroconvulsive therapy remain important. Large randomised pragmatic trials are needed to help clinicians and patients make better treatment choices.

Toolbox: Psychotropic medications for augmentation or combination in treatment-resistant depression

This toolbox compares pharmacologic options for treatment-resistant depression (TRD) that may be considered if the patient fails to experience adequate response or remission despite optimizing antidepressant therapy.

Pharmacological management of treatment resistant depression: a clinical review

Objectives: Treatment resistant depression (TRD), commonly encountered in clinical practice, leads to socioeconomic disability and therapeutic pessimism. This paper reviews evidence for pharmacological approaches used in TRD.

Method: Electronic literature searches were performed using Medline and Psychlit using broad search terms relating to TRD.

Results: Agents that potentiate both serotonin and noradrenaline may allow more patients to achieve full remission. Attention must be paid to dose titration and length of treatment courses in TRD. Augmentation with lithium and switching within antidepressant class or between classes can often improve symptoms but efficacy of other augmentation approaches remains uncertain. Antidepressant combinations and addition of atypical antipsychotics can be useful but combinations of predominantly serotonergic antidepressants should be avoided. Electroconvulsive therapy retains an important role in TRD but pharmacological treatments need to be continued concomitantly.

Conclusions: Good improvement is seen in TRD after vigorous antidepressant treatment but most patients continue to have lower grade symptomatology.

[Evidence-based therapy of depression: S3 guidelines on unipolar depression]

Unipolar depressive disorders are among the most frequent reasons for utilizing the health care system. Although efficacious treatments are available and further advances have recently been made there is still a need for improving diagnostic and therapeutic procedures. Alignment of treatment on evidence-based treatment guidelines establishes an essential mainstay. The new S3 and National Health Care guidelines on unipolar depression, the compilation of which was coordinated by the German Society of Psychiatry, Psychotherapy and Neurology (DGPPN) and which were approved by 29 scientific and professional associations, is the ambitious effort to present state of the art evidence and clinical consensus for the treatment of depression. For pharmacotherapy of depression differentiated recommendations can be given, also separate from and in addition to psychotherapy.
