Brandt J, Bressi J, Lê ML, Neal D, Cadogan C, Witt-Doerring J, Witt-Doerring M, Wright S. Prescribing and deprescribing guidance for benzodiazepine and benzodiazepine receptor agonist use in adults with depression, anxiety, and insomnia: an international scoping review. EClinicalMedicine 2024; 70:102507. [PMID: 38516102 PMCID: PMC10955669 DOI: 10.1016/j.eclinm.2024.102507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 02/03/2024] [Accepted: 02/16/2024] [Indexed: 03/23/2024] Open
Abstract
Background Clinical practice guidelines and guidance documents routinely offer prescribing clinicians' recommendations and instruction on the use of psychotropic drugs for mental illness. We sought to characterise parameters relevant to prescribing and deprescribing of benzodiazepine (BZD) and benzodiazepine receptor agonist (BZRA), in clinical practice guidelines and guidance documents internationally, for adult patients with unipolar depression, anxiety disorders and insomnia to understand similarities and discrepancies between evidence-based expert opinion. Methods A Scoping Review was conducted to characterize documents that offered evidence-based and/or consensus pharmacologic guidance on the management of unipolar depression, anxiety disorders, obsessive-compulsive disorders, post-traumatic stress disorders and insomnia. A systematic search was conducted of PubMed, SCOPUS, PsycINFO and CINAHL from inception to October 13, 2023 and supplemented by a gray literature search. Documents were screened in Covidence for eligibility. Subsequent data-charting on eligible documents collected information on aspects of both prescribing and deprescribing. Findings 113 documents offering guidance on BZD/BZRA use were data-charted. Overall, documents gathered were from Asia (n = 11), Europe (n = 34), North America (n = 37), Oceania (n = 7), and South America (n = 4) with the remainder being "International" (n = 20) and not representative to any particular region or country. By condition the documents reviewed covered unipolar depressive disorders (n = 28), anxiety disorders, obsessive-compulsive disorder and post-traumatic stress disorder (n = 42) and Insomnia (n = 25). Few documents (n = 18) were sufficiently specific and complete to consider as de-prescribing focused documents. Interpretation Documents were in concordance in terms of BZD and BZRA not being used routinely as first-line pharmacologic agents. When used, it is advisable to restrict their duration to "short-term" use with the most commonly recommended duration being less than four weeks. Documents were less consistent in terms of prescriptive recommendations for specific drug, dosing and administration pattern (i.e regular or 'as needed') selection for each condition. Deprescribing documents were unanimously in favor of gradual dose reduction and patient shared decision-making. However, approaches towards dose-tapering differed substantially. Finally, there were inconsistencies and/or insufficiency of detail, among deprescribing documents, in terms of switching to a long-acting BZD, use of adjunctive pharmacotherapies and micro-tapering. Funding The authors received no funding for this work.

Cytokine profile in drug-naïve panic disorder patients. Transl Psychiatry 2022; 12:75.

Abstract
Although accumulating evidence suggests that inflammatory processes play a role in the pathophysiology of mental disorders, few studies have investigated this matter in panic disorder (PD). Furthermore, no studies to date have evaluated cytokine levels in drug-naïve patients with PD. Therefore, little is known about the presence of inflammation at the onset of this disorder. The aim of the present study was to determine the levels of the proinflammatory interleukins IL-1B and IL-2R and the anti-inflammatory cytokine IL-10 in drug-naïve PD patients. Analysis of serum chemokine levels revealed increased proinflammatory activity in the early phase of PD through increased IL-2R and IL-1B levels and a decrease in IL-10 levels in drug-naïve PD patients compared to matched healthy controls. Neurotransmitters and neurocircuits that are targets of inflammatory responses are discussed, followed by an examination of brain-immune interactions as risk factors for PD. This study is the first to identify a proinflammatory cytokine response in drug-naïve PD subjects. These findings indicate that treatments targeting proinflammatory markers may ameliorate anxiety symptoms in PD patients.

Abstract
Panic disorder is a common mental disease with high psychiatric comorbidity. It is considered that a combination of genetic predisposition and a special psychic vulnerability plays a key role in the occurrence of panic disorder. Clinically proven efficacy in the treatment of panic disorder have benzodiazepines, tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors and selective serotonin and norepinephrine reuptake inhibitors; antidepressants from other pharmaceutical groups are also used. Selective serotonin reuptake inhibitors are the first line medicines in the treatment of panic disorder. Atypical antipsychotics may be used for the therapy augmentation in addition to first line drugs. Psychotherapy is used along with medications, and a combination of pharmacotherapy and cognitive behavioral therapy is the best method of treatment.

Abstract
Panic disorder is commonly prevalent in the population, but the treatment response for panic disorder in clinical practice is much less effective than that in our imagination. Increasing evidence suggested existence of a chronic or remitting-relapsing clinical course in panic disorder. In this systematic review, we re-examine the definition of treatment-resistant panic disorder, and present the potential risk factors related to the treatment resistance, including the characteristics of panic disorder, other psychiatric and physical comorbidities, and psychosocial stresses. Furthermore, we summarize the potential pathophysiologies, such as genetic susceptibility, altered brain functioning, brain-derived neurotrophic factor, and long-term inflammation, to explain the treatment resistance. Finally, we conclude the current therapeutic strategies for treating treatment-resistant panic disorder from pharmacological and non-pharmacological views.

Abstract
OBJECTIVES The most important change of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) is the use of dimensional approach to assess the severity of symptoms across different diagnosis. There are 2 purposes in this study: the first purpose was to identify the proportion of outpatients with panic disorder who have suicidal ideation. The second aim was to examine the relationships among panic, agoraphobic symptoms, and suicidal ideation in patients with panic disorder, adjusting by age, social support, and alcohol use. METHODS Sixty patients with panic disorder were recruited from outpatient psychiatric clinics in southern Taiwan. Suicidal ideation in the preceding 2 weeks was measured. The Panic and Agoraphobic Symptoms Checklist, Social Support Scale, Questionnaire for Adverse Effects of Medication for Panic Disorder, and Social Status Rating Scale were used to understand the severity of panic and agoraphobia, social support, drug adverse effects, and social status. Significant variables from the univariate analysis were included in a forward regression model. Then, we used structural equation modeling to fit the model. RESULTS We found that 31.7% of outpatients with panic disorder had had suicidal ideation in the preceding 2 weeks. Multiple regression analysis showed that younger age, current alcohol use, more severe panic symptoms, and less social support were associated with suicidal ideation. In addition, the structural equation model illustrated the recursive model from panic to agoraphobia and suicidal ideation. Agoraphobia had no association with suicidal ideation. Panic symptom was a mediator to suicidal ideation but not agoraphobic symptoms. CONCLUSIONS A high proportion of patients with panic disorder had suicidal ideation. We found that panic symptoms, social support, age, and alcohol use affected suicide and could be identified. The 3-level model from panic to agoraphobia revealed that panic was a predictor of agoraphobia and agoraphobia was not a predictor of panic. This verified the evolution of the diagnostic view of the DSM. Panic symptom was a mediator to suicidal ideation. With the dimensional model in DSM-V, panic symptoms can be used as a marker for greater morbidity and severity.

Abstract
Paroxetine is widely prescribed because it has the indication for multiple psychiatric disorders. Our objective was to assess the effect of short-term administration of paroxetine on low-density lipoprotein cholesterol (LDL-C) levels in both healthy controls (HCs) and in patients with panic disorder (PD). Blood samples for measurement of LDL-C were collected atbaseline, after 8 weeks of paroxetine administration and post-discontinuation in 24 male HCs and nine male patients suffering from PD, for a total of 33 subjects. Paroxetine treatment, both in HCs and PD patients, induced a mean 9% increase per subject in LDL-C that normalized post-discontinuation, suggesting causality. The National Cholesterol Education Program (NCEP) guidelines suggest that this paroxetine-induced increase in LDL-C is clinically significant but would not warrant therapeutic intervention in this population selected to be at low cardiovascular risk. However, the increase in LDL-C levels raised above the threshold of 2.7 mmol/L (100 mg/dL) in 36% of our low-risk subjects. The LDL-C increase in this subgroup would be associated with a minor increase in coronary heart disease (CHD) risk. A similar 9% paroxetine-induced increase in LDL-C observed in the large number of psychiatric patients suffering from comorbid established CHD would be detrimental from a cardiovascular perspective and would oppose the new NCEP therapeutic goals of decreasing LDL-C levels by 30-40% in high and moderately high-risk patients. It is possible that longer treatment duration and use of higher doses of paroxetine would lead to a greater increase in LDL-C.

Abstract
BACKGROUND Because a large proportion of patients with panic attacks receiving approved pharmacotherapy do not respond or respond poorly to medication, it is important to identify additional therapeutic strategies for the management of panic symptoms. This article describes a randomized, rater-blind study comparing low-dose risperidone to standard-of-care paroxetine for the treatment of panic attacks. METHODS Fifty six subjects with a history of panic attacks were randomized to receive either risperidone or paroxetine. The subjects were then followed for eight weeks. Outcome measures included the Panic Disorder Severity Scale (PDSS), the Hamilton Anxiety Scale (Ham-A), the Hamilton Depression Rating Scale (Ham-D), the Sheehan Panic Anxiety Scale-Patient (SPAS-P), and the Clinical Global Impression scale (CGI). RESULTS All subjects demonstrated a reduction in both the frequency and severity of panic attacks regardless of treatment received. Statistically significant improvements in rating scale scores for both groups were identified for the PDSS, the Ham-A, the Ham-D, and the CGI. There was no difference between treatment groups in the improvement in scores on the measures PDSS, Ham-A, Ham-D, and CGI. Post hoc tests suggest that subjects receiving risperidone may have a quicker clinical response than subjects receiving paroxetine. CONCLUSION We can identify no difference in the efficacy of paroxetine and low-dose risperidone in the treatment of panic attacks. Low-dose risperidone appears to be tolerated equally well as paroxetine. Low-dose risperidone may be an effective treatment for anxiety disorders in which panic attacks are a significant component.

Abstract
OBJECTIVE Although effective treatments exist, individuals with depressive and anxiety disorders can remain ill for years. Little is known regarding mental health status and treatment use in this population. This study provided national estimates of the prevalence of persistent depression and anxiety, as well as estimates of illness severity, treatment use, and quality of care in this population. METHODS Data were from a prospective, community-based cohort study of 1,642 adults with probable major depression, dysthymia, panic disorder, or generalized anxiety disorder who were part of a U.S. probability sample. Telephone surveys were conducted during 1997-1998 and again an average of 32 months later. Surveys assessed diagnosis, quality of life, treatment satisfaction, medical conditions, suicidal ideation, insurance, medications, and treatment use. RESULTS At follow-up, 59% no longer met criteria for a disorder. The estimated national prevalence of a persistent depressive or anxiety disorder was 4.7%. In this subgroup, 87% had a chronic comorbid medical disorder. During the past year, 88% had seen a primary care practitioner, and 22% had seen a mental health specialist. Between baseline and follow-up, the percentage using appropriate medication increased (21% to 29%), but there was no significant change in use of appropriate counseling (23% to 19%). Only 12% were receiving both appropriate medication and counseling at follow-up. Treatment was less likely for men and people with less education. Suicidal ideation was present in 51% at follow-up. CONCLUSIONS Strategies are needed to increase treatment use and intensity for people with persistent depressive and anxiety disorders. This may require improved access to mental health specialists.

Abstract
In this report, which is an update of a guideline published in 2002 (Bandelow et al. 2002, World J Biol Psychiatry 3:171), recommendations for the pharmacological treatment of anxiety disorder, obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) are presented. Since the publication of the first version of this guideline, a substantial number of new randomized controlled studies of anxiolytics have been published. In particular, more relapse prevention studies are now available that show sustained efficacy of anxiolytic drugs. The recommendations, developed by the World Federation of Societies of Biological Psychiatry (WFSBP) Task Force for the Pharmacological Treatment of Anxiety, Obsessive-Compulsive and Post-traumatic Stress Disorders, a consensus panel of 30 international experts, are now based on 510 published randomized, placebo- or comparator-controlled clinical studies (RCTs) and 130 open studies and case reports. First-line treatments for these disorders are selective serotonin reuptake inhibitors (SSRIs), serotonin-noradrenaline reuptake inhibitors (SNRIs) and the calcium channel modulator pregabalin. Tricyclic antidepressants (TCAs) are equally effective for some disorders, but many are less well tolerated than the SSRIs/SNRIs. In treatment-resistant cases, benzodiazepines may be used when the patient does not have a history of substance abuse disorders. Potential treatment options for patients unresponsive to standard treatments are described in this overview. Although these guidelines focus on medications, non-pharmacological were also considered. Cognitive behavioural therapy (CBT) and other variants of behaviour therapy have been sufficiently investigated in controlled studies in patients with anxiety disorders, OCD, and PTSD to support them being recommended either alone or in combination with the above medicines.

Abstract
PURPOSE OF REVIEW Although anxiety disorders are acknowledged as chronic, the issue of the pharmacological treatment duration remains unsettled. This review focuses on the long-term outcome of patients with anxiety disorders as demonstrated by randomized controlled trials. RECENT FINDINGS Results from long-term randomized controlled trials of antidepressants in anxiety disorders indicate that maintenance treatment significantly reduces the odds of relapse, whatever the anxiety disorder is. This result appears to be similar to what is reported in long-term studies in depressive disorders. In addition, regarding the natural course of depressive disorders, acknowledged as mostly recurrent, some patients may require very long-term treatment, that is, more than 2 years. Moreover, naturalistic studies in anxiety disorders indicate that the relapse risk after discontinuation is not associated with the treatment duration. Finally, there is no predictor to identify those patients who require long-term pharmacotherapy for anxiety disorders. SUMMARY In light of this review, other long-term studies in anxiety disorders have to be undertaken to identify predictors of relapse after treatment discontinuation. As it is now acknowledged for depressive disorders, some patients may require very long-term pharmacological treatment for anxiety disorders.

Abstract
BACKGROUND Nonfearful panic disorder (NFPD) is a type of panic disorder (PD) that was first described in 1987 among cardiology patients who had panic attacks without the experience of fear. NFPD may be considered a subtype of PD with significant impact on the long-term outcome of chest pain patients. OBJECTIVE The authors sought to explore the long-term outcome of NFPD and PD. METHOD Authors studied 199 patients previously referred to cardiology outpatient investigation because of chest pain. Assessments comprising cardiological and psychiatric (SCID-I) examinations were conducted after 9 years. RESULTS At follow-up, no patients suffered from NFPD, but 18% had panic disorder with fear (PD). There were no significant differences between the baseline NFPD (N=11) and PD (N=44) patients regarding psychiatric comorbidity, chest pain, healthcare utilization, and health-related quality of life at follow-up. CONCLUSION NFPD can have a significant impact on the long-term outcome of chest pain patients even though they may not seek psychiatric treatment.

Abstract
A randomized, controlled trial was conducted to examine the cost-effectiveness of cognitive-behavioral treatment (CBT) for panic disorder with agoraphobia. A total of 100 participants were randomly assigned to standard ( n = 33), group ( n = 35), and brief ( n = 32) treatment conditions. Results show significant clinical and statistical improvement on standard symptom measures and quality of life from baseline to posttreatment and 3-month follow-up, with no significant differences between treatment conditions. Compared with standard CBT, brief and group CBT incurred lower treatment costs and had a superior cost-effectiveness ratio, suggesting the potential of these alternative treatment conditions in increasing access to effective treatment.

Abstract
Panic disorder (PD) is a disabling condition which appears in late adolescence or early adulthood and affects more frequently women than men. PD is frequently characterized by recurrences and sometimes by a chronic course and, therefore, most patients require long-term treatments to achieve remission, to prevent relapse and to reduce the risks associated with comorbidity. Pharmacotherapy is one of the most effective treatments of PD. In this paper, the pharmacological management of PD is reviewed. Many questions about this effective treatment need to be answered by the clinician and discussed with the patients to improve her/his collaboration to the treatment plan: which is the drug of choice; when does the drug become active; which is the effective dose; how to manage the side effects; how to manage nonresponse; and how long does the treatment last. Moreover, the clinical use of medication in women during pregnancy and breastfeeding or in children and adolescents was reviewed and its risk-benefit balance discussed.

Abstract
AIMS The aim was to assess the association between panic disorder (PD) and the long-term outcome of chest pain patients with or without coronary artery disease (CAD). METHODS Patients (n = 199) consecutively referred to a cardiology outpatient clinic because of chest pain were reassessed after 9 years. At the initial examination 16% suffered from CAD and 38% from PD. Data were collected on mortality, cardiac events, cardiac risk factors, chest pain, anxiety and depression (SCL-90-R), and health-related quality of life (SF-36). RESULTS The death rate in the study population was not significantly different from that in the general population and no significant associations were found between PD at baseline and mortality and cardiac morbidity at follow-up. PD was associated with significantly higher follow-up scores of chest pain intensity (p = 0.025), depression (p = 0.005), anxiety (p = 0.039), and poorer health-related quality of life: physical functioning (p = 0.004), role physical (p = 0.001), body pain (p = 0.007), and general health (p < 0.001). CONCLUSIONS PD has a negative long-term effect on psychological and physical well-being of chest pain patients which emphasizes the necessity of identifying PD patients and offering them adequate treatment.

Abstract
RATIONALE Few randomized, placebo-controlled trials have evaluated the comparative efficacy and tolerability of more than one pharmacological agent for panic disorder. OBJECTIVES The primary objective of this study was to compare the efficacy and tolerability of venlafaxine extended release (ER) with placebo in treating panic disorder. Secondary objectives included comparing paroxetine with venlafaxine ER and placebo. METHODS Outpatients aged > or =18 years (placebo, n = 157; venlafaxine ER 75 mg, n = 156; venlafaxine ER 225 mg, n = 160; paroxetine, n = 151), with a primary diagnosis of panic disorder (+/-agoraphobia) based on the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) criteria for > or =3 months were randomly assigned to receive venlafaxine ER (titrated to 75 mg/day or 225 mg/day), paroxetine (titrated to 40 mg/day), or placebo for 12 weeks. The primary efficacy measure was the percentage of patients free of full-symptom panic attacks (> or = four symptoms) at endpoint. Key secondary outcomes included the Panic Disorder Severity Scale (PDSS) mean score change and response. RESULTS At endpoint, all active treatment groups showed a significantly (P < 0.01) greater proportion of patients free of full-symptom panic attacks, compared with placebo, and were superior (P < 0.05) on most secondary measures. The venlafaxine ER 225 mg group had significantly (P < 0.05) greater mean PDSS score improvement than the paroxetine group (-12.58 vs -11.87) and a significantly higher proportion of patients free of full symptom panic attacks (70.0 vs 58.3%). Both drugs were generally well tolerated. CONCLUSION Venlafaxine ER 75 mg/days and 225 mg/days and paroxetine 40 mg/day were both well tolerated and effective for short-term treatment of panic disorder.

Abstract
Anxiety disorders usually are chronic or recurrent disorders characterized by stress sensitivity and a fluctuating course. Both psychopharmacologic and cognitive-behavioral treatments are well-established, evidence-based treatments for panic disorder, social anxiety disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Exposure-based behavioral treatment is well established as evidence-based treatment for specific phobias. Primary care physicians can make a significant impact on patients' lives by identifying and educating about anxiety disorders, directing patients to appropriate self-help resources, choosing evidence-based drug treatment when indicated, and making referrals for specialist care.

Abstract
Consumption rates of anxiolytic drugs, and especially of benzodiazepines, remain very high in France compared to other Western countries, whereas clinical guidelines limit their indications to short term treatments and only for some precise anxiety disorders. Recent epidemiologic surveys in the community indicated that more than 15% of people used once or more an anxiolytic drug in the past year. The issue of chronic treatments is particularly crucial because of their poor benefit/risk ratio in most anxiety disorders (limited efficacy, cognitive side effects, withdrawal and dependence problems). To address this important public health issue, and knowing that, in France, benzodiazepines are prescribed mainly by general physicians, our aims were to explore psychiatric diagnoses in GP's patients with chronic use of anxiolytic benzodiazepines. We included 4 425 patients consuming such drugs regularly for six months or more, and assessed their anxiety and depression symptoms through various clinical scales (Hospital Anxiety and Depressive scale - HAD, Clinical Global Impression scale - CGI, Sheehan Disability Scale - SDS, Cognitive Dependence to Benzodiazepines scale - CDB) and with the Mini International Neuropsychiatric Interview for DSM IV criteria. Only 2.2% of the subjects had neither anxious nor depressive symptoms as indicated by low scores on both subscores (less than 8) of the HAD scale, used as a screener. Nearly three quarters of the 4,257 subjects (73.2%), had CGI scores of at least 5 (markedly ill to extremely ill). Social and familial disability was also high in more than 40% of the sample (marked to extreme disruption according to SDS scores). About half of the sample had CDB scores suggesting a benzodiazepine dependence. According to the MINI, 85.1% of the patients had at least one current DSM IV diagnosis of affective disorder. The most frequent diagnoses were major depressive episode (60%), generalized anxiety disorder (61.2%), and panic disorder (22.5%). An anxiety and depressive comorbidity wad found in 41.9% of the subjects. Some methodological limitations must be taken into account in the discussion of our results, and especially the fact that the included patients were not supposed to be totally representative of all patients consuming anxiolytic benzodiazepines in general practice. However, the size of our sample is sufficiently large to limit possible biases in patient selection. The main result of this study is that a great majority of the patients had significant symptomatology, in particular major depressive episodes and generalized anxiety disorder, often with marked severity and disability. These data are in line with the knowledge of a lack of efficacy of benzodiazepines in depressive and most anxiety disorders, despite long term treatment. They also confirm the current guidelines which recommend prescribing serotoninergic antidepressants, and not benzodiazepines, when long term treatments are needed for severe and chronic affective disorders. This epidemiologic study leads to the conclusion that a specific and attentive diagnostic assessment should be done in all patients receiving benzodiazepines for more than three months, in order to purpose in many cases other long term therapeutic strategies.

Abstract
To date, no large-scale, controlled trial comparing a serotonin-norepinephrine reuptake inhibitor and selective serotonin reuptake inhibitor with placebo for the treatment of panic disorder has been reported. This double-blind study compares the efficacy of venlafaxine extended-release (ER) and paroxetine with placebo. A total of 664 nondepressed adult outpatients who met DSM-IV criteria for panic disorder (with or without agoraphobia) were randomly assigned to 12 weeks of treatment with placebo or fixed-dose venlafaxine ER (75 mg/day or 150 mg/day), or paroxetine 40 mg/day. The primary measure was the percentage of patients free from full-symptom panic attacks, assessed with the Panic and Anticipatory Anxiety Scale (PAAS). Secondary measures included the Panic Disorder Severity Scale, Clinical Global Impressions--Severity (CGI-S) and--Improvement (CGI-I) scales; response (CGI-I rating of very much improved or much improved), remission (CGI-S rating of not at all ill or borderline ill and no PAAS full-symptom panic attacks); and measures of depression, anxiety, phobic fear and avoidance, anticipatory anxiety, functioning, and quality of life. Intent-to-treat, last observation carried forward analysis showed that mean improvement on most measures was greater with venlafaxine ER or paroxetine than with placebo. No significant differences were observed between active treatment groups. Panic-free rates at end point with active treatment ranged from 54% to 61%, compared with 35% for placebo. Approximately 75% of patients given active treatment were responders, and nearly 45% achieved remission. The placebo response rate was slightly above 55%, with remission near 25%. Adverse events were mild or moderate and similar between active treatment groups. Venlafaxine ER and paroxetine were effective and well tolerated in the treatment of panic disorder.

Abstract
Although most individuals with recurrent headache disorders in the general population do not experience severe psychopathology, population-based studies and clinical investigations find high rates of comorbidity between headache and mood and anxiety disorders. When present, psychiatric disorders may complicate headache treatment and portend a poorer treatment response. The negative prognosis associated with psychiatric comorbidity emphasizes the importance of the identification of psychopathology among those with headache beginning at an early age, and suggests that the treatment of psychiatric comorbidity is warranted to improve the outcome of headache management. In this article we describe the mood and anxiety disorders most commonly associated with migraine, tension-type headache, and chronic daily headache. We provide recommendations for the assessment of comorbid mood and anxiety disorders as well as a brief overview of treatment options. Last, we discuss the clinical implications of mood and anxiety disorders on the treatment and outcome of headache.

Abstract
Recent research on headache has focused on identifying the prevalence of psychiatric disorders in headache patients and discerning the impact of psychiatric comorbidity on treatment of headache. The presence of comorbid psychiatric disorders, especially anxiety and depression, in headache patients is now a well-documented phenomenon. Existing but limited empirical data suggest that psychiatric comorbidity exacerbates headache and negatively impacts treatment of headache. Problematically, these findings have not yet eventuated in improved treatments for individuals suffering from both headache and a psychiatric disorder(s). The present article is an attempt to describe the application of cognitive-behavioral therapies (CBT) for depressive and anxiety disorders to headache patients who present with psychiatric comorbidity. We discuss the origins of the chronic care model in relation to CBT, review basic cognitive-behavioral principles in treating depression and anxiety, and offer clinical recommendations for integrating CBT into existing headache treatment protocols. Directions for future research are outlined, including the need for treatment outcome studies that examine the effects of treating comorbid psychiatric disorders on headache (and vice versa) and the feasibility of developing an integrated CBT protocol that addresses both conditions simultaneously.

Abstract
BACKGROUND Panic disorder can be treated with pharmacotherapy, psychotherapy or in combination, but the relative merits of combined therapy have not been well established. OBJECTIVES To review evidence concerning short- and long-term advantages and disadvantages of combined psychotherapy plus antidepressant treatment for panic disorder with or without agoraphobia, in comparison with either therapy alone. SEARCH STRATEGY The Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Registers (CCDANCTR-Studies and CCDANCTR-References) were searched on 11/10/2005, together with a complementary search of the Cochrane Central Register of Controlled Trials and MEDLINE, using the keywords antidepressant and panic. A reference search, SciSearch and personal contact with experts were carried out. SELECTION CRITERIA Two independent review authors identified randomised controlled trials comparing the combined therapy against either of the monotherapies among adult patients with panic disorder with or without agoraphobia. DATA COLLECTION AND ANALYSIS Two independent review authors extracted data using predefined data formats, including study quality indicators. The primary outcome was relative risk (RR) of "response" i.e. substantial overall improvement from baseline as defined by the original investigators. Secondary outcomes included standardised weighted mean differences in global severity, panic attack frequency, phobic avoidance, general anxiety, depression and social functioning and relative risks of overall dropouts and dropouts due to side effects. MAIN RESULTS We identified 23 randomised comparisons (representing 21 trials, 1709 patients), 21 of which involved behaviour or cognitive-behaviour therapies. In the acute phase treatment, the combined therapy was superior to antidepressant pharmacotherapy (RR 1.24, 95% confidence interval (CI) 1.02 to 1.52) or psychotherapy (RR 1.17, 95% CI 1.05 to 1.31). The combined therapy produced more dropouts due to side effects than psychotherapy (number needed to harm (NNH) around 26). After the acute phase treatment, as long as the drug was continued, the superiority of the combination over either monotherapy appeared to persist. After termination of the acute phase and continuation treatment, the combined therapy was more effective than pharmacotherapy alone (RR 1.61, 95% CI 1.23 to 2.11) and was as effective as psychotherapy (RR 0.96, 95% CI 0.79 to 1.16). AUTHORS' CONCLUSIONS Either combined therapy or psychotherapy alone may be chosen as first line treatment for panic disorder with or without agoraphobia, depending on patient preference.

Abstract
OBJECTIVE In this naturalistic and prospective study, personality was assessed in patients with panic disorder (PD), in order to evaluate whether personality features negatively influence the outcome of pharmacological treatment. METHOD Before drug treatment, PD was diagnosed with the Structured Clinical Interview for DSM-IV disorders and personality was assessed with the Structured Interview for DSM-IV Personality Disorders. Moreover, all patients were evaluated with the SCL-90, the Ham-A and Ham-D. Then, patients were randomly treated with paroxetine (33.5+/-13.3 mg/day) or citalopram (34.7+/-15.2 mg/day) and were followed at monthly intervals for 1 year. Absence of full and limited-symptom attacks, anticipatory anxiety, phobic avoidance and depression for 3 months was used to establish remission. The effect of personality traits on each symptom domain was evaluated. RESULTS Seventy-one patients completed the study. Remission rate was 76% for panic attacks and 46% for complete remission. When the effects of age, gender, age of onset and duration of PD, baseline SCL-90 phobic anxiety, Ham-A and Ham-D scores, Axis I comorbidity and the SIDP traits on remission were analyzed in a logistic regression, only borderline traits negatively influenced remission of panic attacks (OR=0.69; 95% CI=0.49-0.96; p=0.03), whereas the number of traits of each personality Cluster and the total number of SIDP traits did not affect the outcome of treatment. CONCLUSIONS This study suggests that in PD patients, borderline features may negatively influence the response to monotherapy with SSRI drugs; therefore, other treatment strategies (i.e., combination of SSRI with psychotherapy) are needed to obtain remission in these patients.

Abstract
Panic disorder is a common mental disorder that affects up to 5% of the population at some point in life. It is often disabling, especially when complicated by agoraphobia, and is associated with substantial functional morbidity and reduced quality of life. The disorder is also costly for individuals and society, as shown by increased use of health care, absenteeism, and reduced workplace productivity. Some physical illnesses (eg, asthma) commonly occur with panic disorder, and certain lifestyle factors (eg, smoking) increase the risk for the disorder, but causal pathways are still unclear. Genetic and early experiential susceptibility factors also exist, but their exact nature and pathophysiological mechanisms remain unknown. Despite an imprecise, although increased, understanding of cause, strong evidence supports the use of several effective treatments (eg, pharmacological, cognitive-behavioural). The adaptation and dissemination of these treatments to the frontlines of medical-care delivery should be urgent goals for the public-health community.

Abstract
Evidence-based medicine combines the best currently available evidence from systematic medical research, together with clinical expertise, in order to provide the best available care for patients. In conjunction with systematic reviews (meta-analyses), a critical review of evidence-based literature forms the basis for the development of clinical treatment guidelines. Current treatment guidelines for generalized anxiety disorder (GAD) advocate the use of selective serotonin reuptake inhibitors (SSRIs) or serotonin-noradrenaline reuptake inhibitors (SNRIs) as the first line of pharmacotherapy. The safety and tolerability profiles of other medications, such as the benzodiazepines, limit their use, especially for long-term treatment. Since data comparing the efficacy in GAD of different SSRIs are limited, selection of one SSRI over another is generally based on consideration of tolerability profiles. Treatment guidelines for patients with social anxiety disorder (SAD) often recommend SSRIs as the first line of medication treatment, as this class has the largest evidence-base in support of efficacy. Less consistent evidence of efficacy exists for other agents, such as reversible inhibitors of monoamine oxidase inhibitor A (RIMAs), and issues of safety are a concern when considering the use of benzodiazepines. Again, there are few head-to-head studies of the SSRIs, and treatment selection is usually made on the basis of tolerability issues. The efficacy and tolerability of the SSRI, escitalopram, has been evaluated in patients with GAD and with SAD. In long-term studies of SAD, escitalopram demonstrated superior efficacy to placebo and paroxetine. It also exhibited a better tolerability profile, as assessed by discontinuation emergent signs and symptoms (DESS), in both patient groups. Furthermore, in relapse prevention trials of SAD, escitalopram conferred a significant benefit relative to placebo.

Abstract
These British Association for Psychopharmacology guidelines cover the range and aims of treatment for anxiety disorders. They are based explicitly on the available evidence and are presented as recommendations to aid clinical decision making in primary and secondary medical care. They may also serve as a source of information for patients and their carers. The recommendations are presented together with a more detailed review of the available evidence. A consensus meeting involving experts in anxiety disorders reviewed the main subject areas and considered the strength of evidence and its clinical implications. The guidelines were constructed after extensive feedback from participants and interested parties. The strength of supporting evidence for recommendations was rated. The guidelines cover the diagnosis of anxiety disorders and key steps in clinical management, including acute treatment, relapse prevention and approaches for patients who do not respond to first-line treatments.

Abstract
BACKGROUND Psychotropic medication use can be employed as an indicator of appropriate treatment for mental disorders. The Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2) offers the first opportunity to characterize Canadian psychotropic medication use on a national level within diagnostic groups as assessed by a full version of the Composite International Diagnostic Interview (CIDI). METHOD We assessed the prevalence of antidepressant, sedative-hypnotic, mood stabilizer, psychostimulant, and antipsychotic use over 2 days overall and in subgroups defined by CIDI-diagnosed disorders and demographics. We employed sampling weights and bootstrap methods. RESULTS Overall psychotropic drug utilization was 7.2%. Utilization was higher for women and with increasing age. With any lifetime CIDI-diagnosed disorder assessed in the CCHS 1.2, utilization was 19.3%, whereas without such disorders, it was 4.1%. Selective serotonin reuptake inhibitors (SSRIs) were the most commonly used antidepressants for those with a past-year major depressive episode (17.8%), followed by venlafaxine (7.4%). Among people aged 15 to 19 years, antidepressant use was 1.8% overall and 11.7% among those with past-year depression; SSRIs made up the majority of use. Sedative-hypnotics were used by 3.1% overall, increasing with age to 11.1% over 75 years. CONCLUSIONS International comparison is difficult because of different evaluation methods, but antidepressant use may be higher and antipsychotic use lower in Canada than in recent European and American reports. In light of the relative lack of contemporary evidence for antidepressant efficacy in adolescents, it is likely that antidepressant use among those aged 15 to 19 years will continue to decline. The increased use of sedative-hypnotics with age is of concern, given the associated risk of adverse effects among seniors.

Abstract
The objective of this double-blind, placebo-controlled randomized withdrawal study was to evaluate the efficacy and safety of sertraline for 8 weeks in treating Japanese patients with DSM-IV panic disorder. Patients (n=394) were initially treated with 8 weeks of open-label sertraline followed by 8 weeks of double-blind treatment with either sertraline (50-100 mg/day) or placebo. Responders during the open-label phase were eligible to be entered into the double-blind phase. Two hundred and forty patients were entered to the double-blind phase and randomly assigned to receive sertraline (n=119) or placebo (n=121). On the primary efficacy measure (relapse), there was no significant difference between the two treatment groups (sertraline 10.1%; placebo 13.2%). However, the frequency of panic attacks was significantly (P=0.012) lower for sertraline compared to placebo. The proportion of sertraline-treated patients who met response criteria (Clinical Global Impression-Improvement Scale score of 1 or 2) at the end of double-blind phase treatment was also significantly (P=0.003) higher for sertraline (89.9%) compared to placebo (74.4%). Panic Disorder Severity Scale total score was significantly (P=0.012) lower in the sertraline group compared to the placebo group. Adverse events during acute treatment were consistent with the known adverse event profile of sertraline, and the incidence of adverse events during the double-blind phase treatment was not different between sertraline and placebo.

Abstract
PURPOSE OF REVIEW Despite repeated recommendations to limit benzodiazepines to short-term use (2-4 weeks), doctors worldwide are still prescribing them for months or years. This over-prescribing has resulted in large populations of long-term users who have become dependent on benzodiazepines and has also led to leakage of benzodiazepines into the illicit drug market. This review outlines the risks of long-term benzodiazepine use, gives guidelines on the management of benzodiazepine withdrawal and suggests ways in which dependence can be prevented. RECENT FINDINGS Recent literature shows that benzodiazepines have all the characteristics of drugs of dependence and that they are inappropriately prescribed for many patients, including those with physical and psychiatric problems, elderly residents of care homes and those with comorbid alcohol and substance abuse. Many trials have investigated methods of benzodiazepine withdrawal, of which the keystones are gradual dosage tapering and psychological support when necessary. Several studies have shown that mental and physical health and cognitive performance improve after withdrawal, especially in elderly patients taking benzodiazepine hypnotics, who comprise a large proportion of the dependent population. SUMMARY Benzodiazepine dependence could be prevented by adherence to recommendations for short-term prescribing (2-4 weeks only when possible). Withdrawal of benzodiazepines from dependent patients is feasible and need not be traumatic if judiciously, and often individually, managed.

Abstract
A substantial number of patients with panic disorder and agoraphobia may remain symptomatic after standard treatment (including selective serotonin reuptake inhibitors, tricyclic antidepressants, benzodiazepines, or irreversible monamine oxidase inhibitors). In this review, recommendations for the treatment of patients with panic disorder and agoraphobia who do not respond to these drugs are provided. Nonresponse to drug treatment could be defined as a failure to achieve a 50% reduction on a standard rating scale after a minimum of 6 weeks of treatment in adequate dose. When initial treatments have failed, the medication should be changed to other standard treatments. In further attempts at treatment, drugs should be used that have shown promising results in preliminary studies, such as venlafaxine.
