Predictors of symptom resolution in panic disorder after one year of pharmacological treatment: a naturalistic study 总被引:1,自引:0,他引:1
OBJECTIVE: In this naturalistic and prospective study, patients with panic disorder (PD) were treated for one year 1) to verify the rate of patients achieving the resolution of full-symptom attacks, limited-symptom attacks, anticipatory anxiety, phobic avoidance and depression; and 2) to identify the predictors of symptom resolution for each domain. METHOD: One hundred patients with PD, according to DSM-IV criteria, participated in the study. In all patients, a baseline and a follow-up with monthly evaluations of SCL-90, Ham-A, Ham-D and panic diaries were carried out over a one-year period. All patients were treated with paroxetine or citalopram. RESULTS: Seventy-one patients completed the study, whereas the remaining 29 dropped out. Among completers, remission of full- and limited-symptom panic attacks was observed in 76 % of patients, whereas complete remission (resolution of panic attacks, anticipatory anxiety, phobic anxiety, and depression) was achieved by only 46 % of patients. Predictors of absence of symptom remissions were obsessive-compulsive disorder (OCD) and recurrent major depression (MD) comorbidity (for panic attacks), pre-treatment severity of anxious symptoms (for anticipatory anxiety), phobic anxiety (for phobic avoidance), and depressive symptoms (for depression). CONCLUSION: This naturalistic study shows that the high comorbidity of OCD and MD and the greater pre-treatment severity of anxious, phobic and depressive symptoms reduced the likelihood of achieving complete remission of symptoms in PD patients who completed the protocol, even though they were adequately treated with SSRI medication. 相似文献

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. 相似文献

BACKGROUND: This 12-week, placebo-controlled study was carried out to compare the relative efficacy of paroxetine, clomipramine, and cognitive therapy in the treatment of DSM-III-R-defined panic disorder with or without agoraphobia. METHOD: After a 3-week single-blind, placebo run-in period, 131 patients were randomly assigned to receive double-blind medication or 12 sessions of cognitive therapy based on the model of Clark. Efficacy assessments included the daily panic attack diary, the Clinical Global Impression scale, the Patient Global Evaluation, the Hamilton Rating Scale for Anxiety, the Marks-Sheehan Phobia Scale, the Montgomery-Asberg Depression Rating Scale, and the Sheehan Disability Scale. RESULTS: Comparisons with placebo revealed significant superiority of paroxetine (20-60 mg/day) and clomipramine (50-150 mg/day) on nearly all outcome measures. On most measures, paroxetine also showed higher efficacy than cognitive therapy. With few exceptions, cognitive therapy did not differ significantly from placebo. The number of subjects becoming panic-free (66%) was higher and the onset of action was faster in the paroxetine-treated group. Treatment with cognitive therapy yielded the highest drop-out rate (26%). CONCLUSION: In this short-term study assessing treatment of panic disorder and agoraphobia, paroxetine and clomipramine were consistently superior to pill placebo, whereas cognitive therapy was superior on only a few measures. 相似文献

INTRODUCTION: Anxiety disorders are highly prevalent and disabling disorders, for which selective serotonin reuptake inhibitor (SSRI) antidepressants are an effective treatment. Escitalopram is the most selective SSRI available. Beyond its well-established efficacy in depression with or without anxiety, preclinical studies have demonstrated that escitalopram has a broad spectrum of anxiolytic activity. AIM OF THE REVIEW: This review focuses on the therapeutic use and the tolerability issues of escitalopram in the treatment of adult patients with panic disorder, generalized anxiety disorder (GAD), social anxiety disorder, and obsessive-compulsive disorder (OCD), on the basis of numerous recent short-term and long-term controlled studies in these disorders. In a 10-week randomised, double-blind trial in patients with panic disorder, escitalopram (flexible doses 5-10 mg/d) was significantly more effective than placebo in reducing the panic attack frequency, with a faster onset of action than citalopram. Fifty percent of escitalopram recipients and 38% of placebo recipients experienced no panic attacks, with a similar incidence of the most common adverse events for both groups. LITERATURE FINDINGS IN PD: In an open-label study in elderly (>65 years) patients with panic disorder, improvement in panic attack frequency and secondary efficacy variables occurred more rapidly in escitalopram than citalopram recipients. LITERATURE FINDINGS IN GAD: In four double-blind, comparative, eight- to 12-week studies in patients with GAD, escitalopram was more effective than placebo and at least as effective as paroxetine in reducing the mean Hamilton Rating Scale for Anxiety total score. Escitalopram 10-20 mg/d demonstrated continued efficacy in a 24-week extension study of short double-blind trials and in a placebo-controlled, double-blind, 24/76-week relapse-prevention study. In this trial, escitalopram recipients showed a significantly longer time to relapse and reduced risk of relapse than placebo recipients, and the risk of relapse was 4.04 times higher in the placebo group than in the escitalopram group. Escitalopram was well tolerated and only 7% patients withdrew, due to adverse events in the escitalopram group, versus 8% in the placebo group. LITERATURE FINDINGS IN SOCIAL PHOBIA: In two randomised, double-blind, 12- and 24-week studies in patients with social anxiety disorder (social phobia), escitalopram 10-20 mg/d was generally more effective than placebo and at least as effective as paroxetine in reducing the mean Liebowitz Social Anxiety Scale total scores. In a 24-week double-blind, placebo-controlled relapse-prevention study, escitalopram recipients had a longer time to relapse and reduced risk of relapse compared with placebo recipients, and significantly fewer escitalopram than placebo recipients relapsed (22% versus 50%). In these studies, the treatment effects of escitalopram were independent of gender, symptom severity and chronicity, and comorbid depressive symptoms, and the drug was tolerated well. LITERATURE FINDINGS IN OCD: Finally, in patients with OCD, escitalopram 20mg/d for 12 weeks was more effective than placebo, and at least as effective as paroxetine 40 mg/day, with respect to a mean reduction from baseline in the Yale-Brown Obsessive Scale total score. In a 24-week, randomised, placebo-controlled relapse-prevention study, the proportion of patients who relapsed in the escitalopram group (23%) was 2.74 times lower than in the placebo group (52%). In both groups, the majority of adverse events reported were mild to moderate. CONCLUSION: On the whole, numerous clinical data indicate that escitalopram, 10-20 mg/d, is an effective and well-tolerated first-line treatment option for the management of panic disorder, GAD, social anxiety and OCD. Beyond short-term demonstrations of efficacy in these disorders, several controlled relapse-prevention studies showed the necessity and utility of maintaining the treatment six months or more after the remission has been obtained. 相似文献

Paroxetine has been shown to be effective in panic disorder in three 10- to 12-week studies. This trial studied the longer term effects of paroxetine in patients with DSM-III-R defined panic disorder. Patients who satisfactorily completed a 12-week, double-blind, placebo-controlled study of paroxetine and clomipramine could choose to continue receiving their randomized treatment for a further 36 weeks. Efficacy assessments included the daily panic attack diary, the Clinical Global Impression Scale, the Hamilton Anxiety Rating Scale, the Marks Sheehan Phobia Scale and the Sheehan Disability Scale. In total, 176 patients were included in the intention-to-treat population. The number of full panic attacks decreased in all three groups during the 12-week study, and improvements continued with long-term therapy. Paroxetine was statistically significantly more effective than placebo throughout the long-term study with respect to reduction from baseline of full panic attacks, and at the end of treatment with respect to the proportion of patients who eventually experienced no panic attacks. There were no significant differences between paroxetine and clomipramine. The proportion of patients who withdrew from the study due to adverse effects was greater in the clomipramine group (19%) than in either the paroxetine group (7%) or the placebo group (9%). Paroxetine was significantly more effective than placebo and as effective as (but better tolerated than) clomipramine in the long-term treatment of panic disorder. Not only was efficacy maintained, but continued improvement was also seen, indicating the importance of long-term treatment in patients with panic disorder. 相似文献

The primary objectives of this multicenter study were to determine the efficacy and safety of moclobemide, a selective reversible inhibitor of monoamino oxidase A, as drug treatment in DSM-III-R panic disorder with and without agoraphobia. In a comparative double-blind, randomized parallelgroup design with fixed-flexible dose moclobemide 450 mg per day was compared to clomipramine 150 mg per day, as that drug was considered standard treatment of panic disorder in Europe. 135 patients were randomized and treated for a period of eight weeks. No other treatment was given. By the end of week 8,49% of the patients treated with moclobemide and 53% of those treated with clomipramine were seen as treatment responders since they were without panic attacks. 78% of the patients in the moclobemide and 88% in the clomipramine group were considered responders according to clinical global impression of change. No significant differences were found between the two treatments at week 8.Adverse events were observed with significantly higher frequency among patients treated with clomipramine, particularly due to anticholinergic side effects. Close to 20% of those treated with moclobemide experienced headache, dizziness, nausea, insomnia, or dry mouth, but other adverse effects were infrequent.In conclusion, moclobemide in a dose of 450 mg per day seems to be a good drug alternative for treatment of panic disorder with and withouth agoraphobia. 相似文献

Analyses in 44 agoraphobic patients given single-blind placebo over a two-week period, without the customary confound of instructions of exposure to phobic situations, replicated previous findings of a weak placebo response in that there were statistically, but not clinically, significant reductions in panic and phobic symptoms. Further analyses of a representative subsample of 10 patients who continued to receive placebo revealed that the placebo response was maintained and even increased at the end of 10 weeks when 20% to 30% of the patients could be classified as marked responders on key panic and phobic measures. Results also revealed an interesting observation that most of the improvement in panic, anxiety, and depression occurred early whereas improvement in phobic measures was more gradual and increased significantly over time. Implications for clinical research are briefly discussed. 相似文献

Escitalopram in the treatment of panic disorder: a randomized, double-blind, placebo-controlled trial 总被引:9,自引:0,他引:9
BACKGROUND: Escitalopram, the therapeutically active isomer of the racemic selective serotonin reuptake inhibitor antidepressant citalopram, has shown significant anxiolytic effects in placebo-controlled clinical trials of social anxiety disorder, generalized anxiety disorder, and anxiety symptoms associated with major depression. This study evaluated the safety and efficacy of escitalopram in outpatients diagnosed with panic disorder. METHOD: Male and female outpatients between 18 and 80 years of age meeting DSM-IV criteria for panic disorder, with or without agoraphobia, were randomly assigned to 10 weeks of double-blind treatment with escitalopram, citalopram, or placebo in a study conducted from September 1999 to July 2001. The primary measure of efficacy was panic attack frequency at week 10 relative to baseline, as assessed by the Modified Sheehan Panic and Anticipatory Anxiety Scale. RESULTS: A total of 366 subjects (128 escitalopram patients, 119 citalopram patients, and 119 placebo patients) received at least 1 dose of double-blind treatment. The frequency of panic attacks was statistically significantly improved (p =.04), and the increase in percentage of patients with zero panic attacks reached borderline significance (p =.051), in the escitalopram-treated group relative to the placebo-treated group. Both escitalopram and citalopram statistically significantly reduced panic disorder symptoms and severity versus placebo at endpoint (p =.05), as measured by the Panic and Agoraphobia Scale total score, the Clinical Global Impressions scale, the Patient Global Evaluation, and the Quality of Life Enjoyment and Satisfaction Questionnaire. Treatment with escitalopram was safe and well tolerated, with a similar incidence of the most common adverse events for the escitalopram and placebo groups. The rate of discontinuation for adverse events was 6.3% for escitalopram, 8.4% for citalopram, and 7.6% for placebo. CONCLUSION: Escitalopram is efficacious, safe, and well tolerated in the treatment of panic disorder. 相似文献

BACKGROUND: Tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs) as well as benzodiazepines have been shown to be effective for the treatment of panic disorder. The introduction of SSRIs has enabled a greater understanding of the role of serotonin in the etiology of panic disorder; however, the role of norepinephrine has been more challenging to ascertain. The aim of this study was to determine the efficacy and tolerability of reboxetine, a novel selective norepinephrine reuptake inhibitor, in patients with panic disorder with and without agoraphobia. METHOD: Eighty-two patients (aged 18-65 years) with DSM-III-R panic disorder, with or without agoraphobia, were randomly assigned to receive 6 to 8 mg/day of reboxetine (42 patients) or placebo (40 patients) for 8 weeks in this placebo-controlled, parallel-group, double-blind clinical trial. RESULTS: Of the 82 patients enrolled in the trial, 75 were considered in the analysis (37 patients in the reboxetine group and 38 patients in the placebo group). At last assessment, there was a significant reduction in the mean number of panic attacks (range, 9.3-1.2) and phobic symptoms (range, 8.1-3.2) in the reboxetine group compared with the placebo group (ranges, 8.5-5.8 and 7.7-5.2, respectively; p < .05). Improvement in Hamilton Rating Scale for Depression, Hopkins Symptom Checklist-90, and Sheehan Disability Scale scores were also greater in the reboxetine group compared with the placebo group. Adverse events reported more frequently with reboxetine than placebo included dry mouth (36% vs. 16%), constipation (27% vs. 22%), and insomnia (26% vs. 22%). CONCLUSION: Reboxetine was effective and well tolerated in the treatment of panic disorder. 相似文献

BACKGROUND: The purpose of this multicenter, double-blind, placebo-controlled study was to evaluate the efficacy and safety of optimized dosages of clonazepam for the treatment of panic disorder and assess the tolerability of a schedule for gradual discontinuation. METHOD: Adult patients with panic disorder with or without agoraphobia (DSM-III-R criteria) were randomly assigned to receive either placebo or clonazepam in individually adjusted doses over 3 weeks to approximate an optimal dosage, which was then maintained for an additional 3 weeks, amounting to a 6-week therapeutic phase. The daily dose range was 0.25 to 4.0 mg administered in 2 divided doses. In the following 7-week discontinuance phase, the doses were tapered gradually to cessation. RESULTS: At the therapeutic endpoint, clonazepam (N = 222) proved clinically and statistically superior to placebo (N = 216) in change in the number of panic attacks and in Clinical Global Impressions-Severity of Illness (CGI-S) and CGI-Change scores, Patient's Global Impression of Change scores, amount of fear and avoidance associated with phobic symptoms, and duration of anticipatory anxiety. The gradual tapering of clonazepam was not associated with symptoms suggestive of withdrawal syndrome. Although patients taking clonazepam experienced some clinical worsening compared with the status achieved at endpoint, particularly in terms of number of panic attacks, no deterioration was observed using their condition at baseline as point of reference. No overall evidence of rebound was found. All regimens were generally well tolerated. Somnolence was the main adverse event associated with clonazepam therapy. The percentage of patients who reported adverse events was higher in the clonazepam group than in the placebo group, as was the mean number of adverse events per patient. CONCLUSION: In this placebo-controlled trial, clonazepam was an efficacious and safe shortterm treatment of the symptoms of panic disorder. Discontinuance during and after slow tapering was well tolerated. 相似文献

OBJECTIVE: To assess the effectiveness of clonazepam, in a fixed dose (2 mg/day), compared with placebo in the treatment of panic disorder patients. METHOD: 24 panic disorder patients with agoraphobia were randomly selected. The diagnosis was obtained using the structured clinical interview for DSM-IV. All twenty-four subjects were randomly assigned to either treatment with clonazepam (2 mg/day) or placebo, during 6 weeks. Efficacy assessments included: change from baseline in the number of panic attacks; CGI scores for panic disorder; Hamilton rating scale for anxiety; and panic associated symptoms scale. RESULTS: At the therapeutic endpoint, only one of 9 placebo patients (11.1%) were free of panic attacks, compared with 8 of 13 (61.5%) clonazepam patients (Fisher exact test; p=0,031). CONCLUSION: the results provide evidence for the efficacy of clonazepam in panic disorder patients. 相似文献

OBJECTIVE: Open-label trials with the selective serotonin reuptake inhibitor citalopram suggest that this agent is effective and safe for the treatment of depressive symptoms in children and adolescents. The current study investigated the efficacy and safety of citalopram compared with placebo in the treatment of pediatric patients with major depression. METHOD: An 8-week, randomized, double-blind, placebo-controlled study compared the safety and efficacy of citalopram with placebo in the treatment of children (ages 7-11) and adolescents (ages 12-17) with major depressive disorder. Diagnosis was established with the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version. Patients (N=174) were treated initially with placebo or 20 mg/day of citalopram, with an option to increase the dose to 40 mg/day at week 4 if clinically indicated. The primary outcome measure was score on the Children's Depression Rating Scale-Revised; the response criterion was defined as a score of < or =28. RESULTS: The overall mean citalopram dose was approximately 24 mg/day. Mean Children's Depression Rating Scale-Revised scores decreased significantly more from baseline in the citalopram treatment group than in the placebo treatment group, beginning at week 1 and continuing at every observation point to the end of the study (effect size=2.9). The difference in response rate at week 8 between placebo (24%) and citalopram (36%) also was statistically significant. Citalopram treatment was well tolerated. Rates of discontinuation due to adverse events were comparable in the placebo and citalopram groups (5.9% versus 5.6%, respectively). Rhinitis, nausea, and abdominal pain were the only adverse events to occur with a frequency exceeding 10% in either treatment group. CONCLUSIONS: In this population of children and adolescents, treatment with citalopram reduced depressive symptoms to a significantly greater extent than placebo treatment and was well tolerated. 相似文献

At the end of a two-week single-blind placebo baseline, 43 patients with a diagnosis of panic disorder with agoraphobia without significant dysphoria-depression and with moderate to severe panic and phobic symptoms were assigned to, and 32 of them completed, a placebo-controlled (n = 7) dose-response study with three weight-adjusted imipramine hydrochloride dosages: 0.5 mg/kg/d (n = 10), 1.5 mg/kg/d (n = 9), and 3 mg/kg/d (n = 6). Eleven patients, three from the medium-dose and eight from the high-dose conditions, dropped out owing to side effects. No instructions or encouragement for self-directed exposure to phobic situations or other coping strategies with panic or fear were given throughout the trial. Compliance, as assessed by pill counts and by plasma tricyclic levels, was high. Results provided strong evidence for a positive dose-response relationship on panic and phobic symptoms and confirmed earlier suggestions (1) that imipramine without concurrent exposure possesses a significant antipanic and antiphobic effect, (2) that improvement correlates primarily with imipramine but not N-desmethylimipramine plasma levels, and (3) that side effects prevent optimum dose buildup in a substantial proportion of patients with this disorder. 相似文献

A double-blind 12 week trial was undertaken to compare the effects of clomipramine + dixyrazine with clomipramine + placebo in the treatment of panic disorder with or without agoraphobia. Of 45 patients included (21 dixyrazine, 24 placebo), 16 dropped out (6 dixyrazine, 10 placebo). The number of panic attacks and the scores on the panic disorder subscale of the Hamilton Anxiety Rating Scale were significantly reduced in response to both treatment regimens, but the reduction was significantly greater in the dixyrazine group. The patients’ daily functioning was significantly more improved with the dixyrazine combination. The serum concentration of desmethylclomipramine monotherapy was significantly higher and the side effects significantly lower in the combined treatment with dixyrazine than with clomipramine monotherapy. Clomipramine combined with dixyrazine seems superior to clomipramine in the treatment of panic disorder. 相似文献

BACKGROUND: A new 13-item scale has been developed for measuring severity of illness in patients with panic disorder and agoraphobia, the Panic and Agoraphobia Scale (P & A). The scale has five subscales covering the main factors that reduce quality of life in panic disorder patients (panic attacks, avoidance, anticipatory anxiety, disability and worries about health). The application of this scale in a double-blind placebo-controlled panic disorder trial is described. At the same time, the aim of the study was to compare the therapeutic effects of aerobic exercise with a treatment of well-documented efficacy. METHODS: Patients with Panic disorder (DSM-IV) were randomly assigned to three treatment modalities: running (n=45), clomipramine (n=15) or placebo (n=15). Treatment efficacy was measured with the Panic and Agoraphobia Scale (P & A) and other rating scales. RESULTS: According to the P & A and other scales, both exercise and clomipramine led to a significant decrease of symptoms in comparison to placebo treatment. Clomipramine was significantly more effective and improved anxiety symptoms significantly earlier than exercise. The evaluation of the P & A subscales revealed that exercise exerted its effect mainly reducing anticipatory anxiew and panic-related disability. CONCLUSIONS: The new Panic and Agoraphobia Scale was shown to be sensitive to differences between different panic treatments. Analysis of the scales five subscores may help to understand mechanisms of action of panic disorder treatments. 相似文献

Serotonergic implication in panic disorder has been demonstrated by the efficacy of serotonin reuptake blockers in treatment. Fluoxetine, a potent 5-HT reuptake blocker, has been suggested to have anti-panic efficacy. This open study examines 30 patients (eight males and 22 females) with an average age of 36.9 years, ranging from 18 to 62, who were treated for eight weeks with fluoxetine (mean dose 20 mg per day). All patients fulfilled DSM-III-R criteria of panic disorder with agoraphobia as determined in a SCID interview schedule. Out of 28 patients who started medication, 64% of the patients completed the clinical trial and 36% of the patients dropped out of treatment because of increased anxiety or a lack of efficacy. Thirty-two percent of the patients had zero panic attacks by week 3. By the end of eight weeks of treatment, 48% of the patients had zero panic attacks. There was a significant reduction in anxiety and phobic avoidance and panic attacks. Tritiated platelet imipramine and paroxetine bindings revealed significantly lower maximal binding for patients with panic disorder in comparison with controls. Paroxetine Bmax showed a trend to increase in the direction of control values by the end of the trial. 相似文献

BACKGROUND: Both cognitive-behavioral therapy and treatment with selective serotonin reuptake inhibitors (SSRIs) have proved to be effective in the treatment of panic disorder. The present study examined the effects of paroxetine added to continued cognitive-behavioral therapy in patients who were unsuccessfully treated with initial cognitive-behavioral therapy alone. METHOD: 161 patients with panic disorder with or without agoraphobia (DSM-IV criteria) underwent a manual-guided cognitive-behavioral therapy of 15 sessions. Forty-three unsuccessfully treated patients from this group were included in a double-blind, placebo-controlled, next-step treatment study consisting of continued cognitive-behavioral therapy plus adjunctive paroxetine at a dose of 40 mg/day or continued cognitive-behavioral therapy plus placebo. RESULTS: Overall, patients in the cognitive-behavioral therapy plus paroxetine condition improved significantly on agoraphobic behavior (p < .05) and anxiety discomfort (p < .01), whereas patients in the cognitive-behavioral therapy plus placebo condition did not. Effect sizes in the cognitive-behavioral therapy plus paroxetine condition ranged from 1.0 to 1.8 and in the cognitive-behavioral therapy plus placebo condition, from 0.4 to 1.0. CONCLUSION: Patients with panic disorder who are unsuccessfully treated with initial cognitive-behavioral therapy may benefit from the addition of an SSRI as a second treatment modality. The importance of timely evaluation of treatment results is emphasized. 相似文献

We investigated the comparative efficacy of citalopram vs. citalopram administered with clomipramine, in treatment-resistant obsessive-compulsive disorder (OCD). Sixteen adult outpatients participated in a 90-day, randomized, open-label trial. Eligible patients were aged 18 to 45 years, had moderate to severe DSM-III-R OCD of >/= one year's duration, a baseline Yale-Brown scale (Y-BOCS) score of >/= 25 and no other active axis I diagnosis, and had failed adequate clomipramine and fluoxetine trials. The citalopram-plus-clomipramine group (n = 9) experienced a significantly larger percent decrease in mean Y-BOCS score by day 90 than the citalopram alone group (n = 7). Only one citalopram patient decreased her score by >/= 35%, and two by >/= 25%. All nine citalopram-plus-clomipramine patients experienced decreases of 35%. Side effects were mild to moderate in both groups. We also treated with citalopram six OCD patients who had not tolerated fluoxetine alone and clomipramine alone; three achieved Y-BOCS score decreases of >/= 35% at 90 days. Since citalopram does not significantly affect clomipramine metabolism, the improvement in the combined drug group is unlikely to have resulted from increased plasma clomipramine levels. Double-blind controlled trials are needed of citalopram in OCD, and of combining citalopram with clomipramine in treatment-resistant OCD. 相似文献

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. 相似文献
