Cognitive-behavior therapy for discontinuation of SSRI treatment of panic disorder: a case series

Barriers to discontinuing antidepressants in patients with depressive and anxiety disorders: a review of the literature and clinical recommendations

Use of antidepressants has recently increased, mainly caused by the increase of long-term users. Although evidence-based indications for long-term use are lacking, it is assumed that long-term use is unnecessary or undesirable in some patients. Perceived barriers to discontinuing antidepressants contribute to unnecessary or undesirable long-term use. Identifying barriers prior to, during and following discontinuation may enable strategies to overcome them. This narrative review summarises relevant qualitative and quantitative articles on perceived barriers to discontinuing antidepressants and provides recommendations for clinical practice. We can conclude that implications for clinical practice are diverse and the most important barriers experienced by patients and physicians include the fear of relapse or recurrence, insufficient evaluation and monitoring, withdrawal symptoms, and actual relapse or recurrence.

Unified protocol for the discontinuation of long-term serotonin reuptake inhibitors in obsessive compulsive disorder: Study protocol and methods

Obsessive-compulsive disorder (OCD) is chronic psychiatric disorder associated with high rates of functional impairment and decreased quality of life. Although serotonin reuptake inhibitors have demonstrated efficacy in the treatment of OCD, little data is available to guide clinicians on how to manage these medications long-term. Cognitive-behavioral approaches provide a promising avenue for helping OCD patients discontinue maintenance SRIs while minimizing the potential for symptom worsening. This manuscript describes the rationale and methods for pilot feasibility study designed to a unified, cognitive-behavioral strategy for discontinuing long-term SRIs in OCD. The aims of the study are (1) to evaluate the feasibility and acceptability of research procedures and interventions, (2) to test the efficacy of this treatment relative to an enhanced control condition and (3) to investigate the role of distress tolerance in both taper completion and clinical outcome. Our central aim is to investigate whether this approach improves discontinue outcomes relative to an enhanced control condition. Identifying optimal long-term treatment strategies for this population is needed to guide clinicians managing this often-chronic disorder.

Five sessions and counting: considering ultra-brief treatment for panic disorder

BACKGROUND

Brief cognitive-behavioral therapy for panic disorder has the potential to lower health care costs and enhance dissemination of evidence-based interventions to clinical practice. This manuscript evaluates the utility of brief cognitive-behavioral therapy for panic disorder.

METHODS

A narrative review of studies examining the efficacy of cognitive-behavioral brief treatment of panic disorder, with a specific focus on an ultra-brief, 5-session, intervention developed by our group.

RESULTS

Brief cognitive-behavioral therapy for panic disorder is associated with clinically meaningful symptom improvement reflecting large effect sizes, comparable to those observed for standard protocols.

CONCLUSIONS

Growing evidence encourages the further evaluation and application brief cognitive-behavioral therapy for panic disorder. Controlled trials of cognitive-behavioral therapy have established the dramatic benefit that can be offered by brief treatment (often 12-15 sessions) approaches for Axis I disorders. Yet, as the field advances and core mechanisms of change are identified, there is the potential for offering efficacy in even briefer treatment protocols. In this manuscript, we describe the elements and initial efficacy estimates, based on published studies, for an ultra-brief treatment approach for panic disorder. We also discuss the potential impact, and such brief treatment can have relative to dissemination issues and the desire for the timely end to psychological suffering.

Evidence-based pharmacotherapy of panic disorder: an update

The evidence-based pharmacotherapy of panic disorder continues to evolve. This paper reviews data on first-line pharmacotherapy, evidence for maintenance treatment, and management options for treatment-refractory patients. A Medline search of research on pharmacotherapy was undertaken, and a previous systematic review on the evidence-based pharmacotherapy of panic disorder was updated. Selective serotonin reuptake inhibitors remain a first-line pharmacotherapy of panic disorder, with the serotonin noradrenaline reuptake inhibitor venlafaxine also an acceptable early option. Temporary co-administration of benzodiazepines can be considered. Maintenance treatment reduces relapse rates, but further research to determine optimal duration is needed. For patients not responding to first-line agents several pharmacotherapy options are available, but there is a notable paucity of data on the optimal choice.

Efficacy of CBT for benzodiazepine discontinuation in patients with panic disorder: Further evaluation

Despite its acute efficacy for the treatment of panic disorder, benzodiazepines (BZs) are associated with a withdrawal syndrome that closely mimics anxiety sensations, leading to difficulty with treatment discontinuation and often disorder relapse. An exposure-based cognitive-behavioral treatment for BZ discontinuation, Panic Control Treatment for BZ Discontinuation (CBT) targets the fear of these sensations and has demonstrated efficacy in preventing disorder relapse and facilitating successful BZ discontinuation among patients with panic disorder. In this randomized controlled trial, CBT was compared to taper alone and a taper plus a relaxation condition to control for the effect of therapist contact and support among 47 patients with panic disorder seeking taper from BZs. Based on the primary outcome of successful discontinuation of BZ use, results indicate that adjunctive CBT provided additive benefits above both taper alone and taper plus relaxation, with consistently medium and large effect sizes over time that reached significance at the six month follow-up evaluation. The efficacy of CBT relative to either of the other taper conditions reflected very large and significant effect sizes at that time. These findings suggest that CBT provides specific efficacy for the successful discontinuation from BZs, even when controlling for therapist contact and relaxation training.

Predictors of relapse in the second follow-up year post cognitive-behavior therapy for panic disorder

OBJECTIVE: To investigate predictors of relapse two years after a brief cognitive-behavior group therapy in patients with panic disorder who had failed to respond to pharmacologic treatment. METHOD: A total of 56 patients with panic disorder were followed who had met remission criteria at 1 year evaluation after 12 sessions of cognitive-behavior group therapy. Demographic and clinical features and life stressors were investigated as predictors of relapse. RESULTS: At the 2 year assessment, 39 (70%) patients maintained remission status and use of medication was reduced significantly, such that 36 (64%) patients were not undergoing any psychiatric treatment. Among all independent variables investigated, only "conflict" as a stressful life event, RR = 3.20 (CI95% 1.60; 7.20 - p = 0.001), and the severity or residual anxiety symptoms, RR = 3.60 for each scale point (CI95% 1.02; 1.08 - p < 0.001), emerged as nonredundant predictors. CONCLUSION: In spite of the high treatment gains across two years of follow-up, clinicians should pay attention to stress management and to the role of residual symptoms during this period. Results were discussed in the context of treatment cost-efficacy and potential strategies to prolong treatment gains from cognitive-behavior group therapy.

Empirically supported treatments for panic disorder

This article provides an empirical review of the elements and efficacy of both pharmacologic and psychosocial treatments for panic disorder. Both monotherapies and combination treatment strategies are considered. The available evidence suggests that both cognitive behavioral therapy (CBT) and pharmacotherapy (prominently, selective serotonin reuptake inhibitors or serotonin-norepinephrine reuptake inhibitors) are effective first-line agents and that CBT offers particular cost efficacy relative to both pharmacotherapy alone and combined pharmacotherapy and CBT. Predictors of non-response and mechanisms of action are considered, as are novel treatment strategies, including the use of memory enhancers to improve CBT outcome.

[Cognitive-behavioral therapy in panic disorder]

OBJECTIVE

Panic disorder is a chronic and recurrent condition that impairs an individual's psychosocial functioning and quality of life. Despite the efficacy of psychopharmacological treatment in reducing panic attacks, many patients fail to respond adequately to these interventions. Cognitive behavioral therapy provides an alternative and efficacious method for treating panic disorder and agoraphobic avoidance. The objective of the study is to describe the use of cognitive behavioral therapy for panic disorder.

METHOD

Narrative review of data collected from Medline, SciELO and PsycInfo and specialized textbooks.

RESULTS

We describe the cognitive-behavioral model for the treatment of panic disorder, and review both short and long-term efficacy findings. We also discuss the role of combined treatment (cognitive behavioral therapy and psychopharmacology).

CONCLUSIONS

Cognitive behavioral therapy, either individual or in group, can be used as first-line therapy for panic disorder. This treatment modality can also be indicated as a next step for patients failing to respond to other treatments.

Pharmacotherapy of Mood Disorders and Treatment Discontinuation

Depression is the most frequent and costly problem in primary care, where most of these patients are seen and treated. In many countries, the public regard antidepressant drugs as 'addictive', partly because of the withdrawal symptoms that can occur when they are discontinued. Indeed, discontinuation (withdrawal) symptoms can follow the stoppage of almost all classes of antidepressants, including selective serotonin receptor inhibitors (SSRIs). This is important because they are widely regarded as drugs of choice for both depression and the anxiety disorders. But is this true withdrawal or merely rebound? The antidepressant discontinuation syndrome is characterised by the time-locked emergence of new, clearly defined and quantifiable signs and symptoms that ensue on stopping or reducing the dose of an antidepressant. Thereby, it meets the criteria for a withdrawal syndrome. The symptoms are not usually severe or protracted. SSRIs vary in their propensity to be associated with a discontinuation syndrome: paroxetine appears to be the most likely. Patients should be warned of the possibility of developing such a reaction, but reassured that it is usually mild and self limiting. Tapering the dose, if practicable, is worthwhile. In severe cases, temporary reinstatement of the SSRI and slower tapering may be necessary. Escalation of antidepressant dosage, or 'street abuse', is rare with antidepressants. The use of antidepressants is generally beneficial, and efforts should be made to optimise our current use of these drugs as well as encouraging the development of newer, better and innovative compounds. To this end, physicians should educate themselves and the public about discontinuation and withdrawal, so that these clinical features can be put in a realistic context.

Combining Cognitive-Behavioral Therapy and Pharmacotherapy for the Treatment of Panic Disorder

This article focuses on the role of combination treatment strategies in the management of panic disorder (PD). Despite short-term benefits, there is not consistent evidence for a longer-term advantage of combined treatment over cognitive-behavior therapy alone. In discussing this result, we place emphasis on ways in which medication treatment may interfere with the learning of safety in relation to feared cues in PD. These considerations are placed in the context of animal and human studies of factors that interfere with the extinction of fears. Strategies to overcome this interference are also discussed as are novel approaches to combination treatment.

Combined Treatment for Social Anxiety Disorder

Despite scant evidence of an advantage of combining medication and cognitive behavioral therapy (CBT) for social anxiety disorder, the advantages and disadvantages of the two approaches suggest the possibility that some form of combination may be helpful for many clients. At the same time, the available evidence and theoretical considerations suggest that some methods of combination could provide short-term benefits but long-term decreases in efficacy compared to either treatment alone. Thus, current knowledge suggests that, for social anxiety disorder, more treatment is no substitute for well-informed treatment. We provide guidelines for treatment based on available evidence, theoretical models, and clinical experience. Overall, the clearest case for combination treatment is for the addition of an empirically supported CBT for social anxiety disorder following the stabilization of response to an empirically supported psychopharmacological agent. The CBT should then be modified to address the use of medication, the possibility of relapse, and, ideally, the tapering of medication during CBT. Further research is called for in order to support these recommendations and extend the available literature.

Do Medications Matter in the Context of Cognitive Behavior Therapy for Panic Disorder?

Patients with panic disorder are frequently medicated when they participate in psychotherapy such as cognitive behavioral therapy (CBT). The present study examined the effects of overall medication status, medication type (benzodiazepine versus antidepressant), and medication dose in a large sample of patients with panic disorder (N = 178) participating in CBT. Overall, medications exhibited very little effect on outcome. After controlling for the effects of CBT, however, taking higher doses of antidepressants was associated with poorer end-state functioning. Results are discussed in relation to better understanding the role of combining psychopharmacological and psychosocial treatments for panic disorder.

Panic disorder

BACKGROUND

This article reviews the clinical features, epidemiology, pathophysiology, dental findings, and dental and medical management of the care of patients with panic disorder, or PD.

TYPES OF STUDIES REVIEWED

The authors conducted a MEDLINE search for the period 1998 through 2003, using the key term "panic disorder" to define the pathophysiology of the disorder, its epidemiology and dental implications. The articles they selected for further review included those published in peer-reviewed journals.

RESULTS

PD is a common and debilitating psychiatric disease in which a person experiences sudden and unpredictable panic attacks, or PAs, with symptoms of overwhelming anxiety, chest pain, palpitations and shortness of breath. Persistent concern about having another attack and worry that it may indicate a heart attack or "going crazy" impairs the person's social, family and working lives. Frequently accompanying the disorder is agoraphobia, depression and mitral valve prolapse, or MVP.

CLINICAL IMPLICATIONS

In patients with PD, the prevalence of dental disease may be extensive because of the xerostomic effects of psychiatric medications used to treat it. Dental treatment consists of preventive dental education and prescribing saliva substitutes and anticaries agents. Precautions must be taken when prescribing or administering analgesics, antibiotics or sedative agents that may have an adverse interaction with the psychiatric medications. Because there is a connection between PAs and MVP, the dentist needs to consult with the patient's physician to determine the presence of MVP and whether there is associated mitral valve regurgitation. Patients with MVP and accompanying mitral valve regurgitation require prophylactic antibiotics when undergoing dental procedures known to cause a bacteremia and heightened risk of endocarditis.

Modelos de tratamento para o transtorno do pânico

O Transtorno do Pânico tem sido um problema de saúde importante, apesar de não ser o transtorno ansioso mais freqüente. Ele está associado a uma diminuição marcante da qualidade de vida. No Transtorno do Pânico, é comum a procura contínua por serviços médicos em busca de uma explicação para os sintomas físicos e psicológicos apresentados. Entretanto, a falha no diagnóstico é habitual nestas situações, reforçando o comportamento de visitas repetidas a serviços médicos, aumentando os custos sociais e econômicos. Estes custos poderiam ser minimizados por meio de tratamentos bem estabelecidos e eficientes, como os tratamentos com medicamentos e psicoterapia comportamental-cognitiva. Estudos recentes mostraram que a combinação medicamentos antidepressivos e psicoterapia comportamental-cognitiva tem sido mais indicada pelos bons resultados obtidos. Este trabalho tem como objetivo discutir os principais modelos de tratamento para o Transtorno do Pânico.

Treating medication-resistant panic disorder: predictors and outcome of cognitive-behavior therapy in a Brazilian public hospital

BACKGROUND

In Brazil, treatment of panic disorder is most frequently initiated with pharmacotherapy, but only half of the patients can be expected to be panic free after medication. Studies have suggested that individual or group cognitive-behavior therapy (CBT) is an effective treatment strategy for panic patients who have failed to respond to pharmacotherapy.

METHODS

Thirty-two patients diagnosed with panic disorder with agoraphobia having residual symptoms despite being on an adequate dose of medication were treated with 12 weeks of group CBT. The outcome was evaluated for panic frequency and severity, generalized anxiety, and global severity. Comorbid conditions, a childhood history of anxiety, and defense mechanism styles were assessed as potential predictors of treatment response.

RESULTS

Twenty-nine patients completed the 12-week protocol. Treatment was associated with significant reductions in symptom severity on all outcome measures (p < 0.001). Patients with depression had a poorer outcome of the treatment (p = 0.01) as did patients using more neurotic (p = 0.002) and immature defenses (p = 0.05).

CONCLUSION

Consistent with previous reports, we found that CBT was effective for our sample of treatment-resistant patients. Among these patients, depression as well as neurotic defense style was associated with a poorer outcome. The use of CBT in Brazil for treatment-resistant and other panic patients is encouraged.
