Efcacy mean nal dose is approximately 150 mg/day of imip Alprazolam has been studied more extensively than any ramine and the maximum nal dose is up to 300 mg/day. They found that both the medium National Collaborative Panic Study, which involved more and high doses were superior to placebo in reducing panic than 1,000 patients randomly assigned to receive imip and not signicantly different from each other; the low ramine, alprazolam, or placebo (594). There is a suggestion in the literature that clomip Two meta-analyses of studies on alprazolam treatment for ramine may be effective in somewhat lower doses than panic disorder are also available (402, 586). Clomipramine can generally be used effec In six of the seven double-blind, placebo-controlled tively with doses less than 150 mg/day. Cassano and colleagues (99) continued to who were originally assigned to receive active treatment treat patients with imipramine or placebo for 6 months af or placebo at the start of the trial); the differences between ter an acute-phase 8-week study and found that imi the completers were less striking or nonsignicant be pramine remained superior to placebo for panic cause of higher dropout rates for the nonresponders in the reduction. Alprazolam was superior to placebo in re tients on a regimen of placebo or imipramine for up to 8 ducing agoraphobic avoidance in ve of the six studies in months after acute 8-week treatment and found that the which it was assessed, disability in ve of ve studies, an placebo-treated patients had more panic attacks and ago ticipatory anxiety in three of three studies, and Hamilton raphobic avoidance and were more likely to drop out of anxiety scale scores in six of seven studies. The limited studies, patients with primary current major depression available data are mixed about whether patients who remit were excluded and the level of agoraphobic avoidance was during treatment benet more from over a year of subse moderate. More dropouts occurred in the imip fects of these agents in people with panic disorder. The there were no long-term memory decits, suggesting that agents studied include clonazepam (effective in the three there is no carryover effect after medication has been dis double-blind, placebo-controlled trials and the only other continued (597). One study the ndings and because many studies have serious meth showed superiority of imipramine over chlordiazepoxide. Furthermore, data in the more se the adverse effects of benzodiazepines in patients with verely ill Medicaid population with a mix of mostly mood panic disorder appear similar to those reported when ben and anxiety disorder diagnoses show that long-term use of zodiazepines are used for other indications. They include benzodiazepines (at least 2 years) does not typically result primarily sedation, fatigue, ataxia, slurred speech, memory in dose escalation, with the incidence of escalation to a impairment, and weakness. In addition, an in use, especially in specic cohorts of patients with panic creased risk of motor vehicle accidents in association with disorder, are lacking, making it difcult to draw denitive benzodiazepine use has been reported (288). In geriatric conclusions about the potential for benzodiazepine toler patients, the risk of falls and fractures appears to be greater ance in the clinical treatment of panic disorder. Practice Guideline for the Treatment of Patients With Panic Disorder 59 of treatment. Another study showed that, compared with end was found for 65% of patients taking the higher dose, imipramine, alprazolam causes signicantly more with 50% of those taking the lower dose, but only 15% of those drawal symptoms, recurrent panic attacks, and inability to taking placebo (278). An additional study sug benzodiazepine use for the lower-dose (23%) and placebo gested that patients with panic disorder have more diffi(35%) patients were considerably greater than the rate for culty during tapering of alprazolam than do those with the patients taking the higher alprazolam dose (4%) (278), generalized anxiety disorder, even when the patients in perhaps suggesting that the patients did not nd the lower both groups are treated with similar doses (599). In addition, adverse ties during alprazolam tapering seem most severe during side effects were more pronounced at the higher dose than the last half of the taper period and the rst week after the at the lower dose of alprazolam in that study. In many instances, it is diffiIn one multicenter dose-ranging trial, patients with cult to determine the extent to which symptoms are occur panic disorder were randomly assigned to placebo or one ring because of withdrawal, rebound, or relapse. During 6 panic disorder indicated that both are no different from weeks of treatment, the minimum effective dose was 1 placebo during gradual tapering of the rst half of the mg/day, and daily doses of 1 mg/day and higher were dose (600). With abrupt discontinuation of the remaining equally effective in reducing the number of panic attacks. Diaz are more difculties with short half-life, high-potency epam doses ranged from 5 mg/day to 40 mg/day in two compounds. Length of treatment long half-lives or high versus low potency has not been Very few data indicate the optimum length of maintenance adequately addressed in relation to panic disorder. Two published dition, studies by Schweizer, Rickels, and associates (126, trials have compared maintenance imipramine, alprazolam, 351) of benzodiazepine-treated patients with other psy and placebo treatment, and both suggested that imip chiatric disorders show no signicant effect of half-life on ramine may be superior. In the study by Cassano and col the results of a gradual taper, but greater withdrawal se leagues (99), patients who received imipramine and those verity after abrupt discontinuation with compounds that who received alprazolam fared equally well in terms of have shorter half-lives and with higher daily doses. Taken panic reduction during a 6-month maintenance phase, but together, these studies suggest that half-life is less of a fac the imipramine-treated patients had less agoraphobic tor, or in fact may not be important, given a gradual taper avoidance. Curtis and associates (104) found that from disorder, after accounting for the effects of dose and dura month 4 through the end of an 8-month maintenance tion of alprazolam use, as well as pretreatment anxiety and phase patients taking imipramine had virtually no panic at panic frequency, measures of anxiety symptom sensitivity tacks, whereas alprazolam-treated patients continued to ex and avoidance predicted difculty discontinuing alpraz perience infrequent panic attacks. Dose third investigation by Lepola and colleagues (602), 27 pa Very few studies have empirically evaluated dosing of ben tients who had been treated with alprazolam and 28 pa zodiazepines for panic disorder. Two studies compared al tients who had been treated with imipramine in a 9-week prazolam doses of 6 mg/day and 2 mg/day (95, 278).

Reboxetine tors, but no placebo, showed comparable efcacy to both Reboxetine, a norepinephrine reuptake inhibitor, is cur uoxetine (298) and clomipramine (299), respectively, the rently not available for use in the United States or Canada. Anticonvulsants panic disorder treated with trazodone found signicant There are limited data concerning the use of anticonvul improvement in panic symptoms compared to a baseline sant medications in the treatment of panic disorder. One period of placebo treatment (307), a double-blind study in randomized controlled trial of gabapentin in 103 patients which 74 patients with panic disorder were assigned to with panic disorder provided partial support for its effitrazodone, imipramine, or alprazolam showed trazodone cacy and safety (321). The only other randomized study, a to be less effective than either imipramine or alprazolam small placebo-controlled trial, suggested that carbamaze (221). Further, a study of trazodone exibly dosed from 50 pine was not effective for panic disorder (328). Antipsychotic agents Bupropion has been found to be effective in the treatment There is minimal evidence that rst-generation antipsy of depression, but there is little systematic study of its effichotic medications are effective for panic disorder. In small cacy in panic disorder, and the available data are contradic open-label trials, signicant reductions in symptoms were tory. Two small uncontrolled trials have been published, observed in patients with treatment-resistant panic disor one positive and one negative. In the positive trial, which der treated with olanzapine (329) and adjunctive risperi included 20 patients, bupropion sustained release exibly done (330).

This is a potentially order, more research is needed to optimize these fruitful avenue for research on enhancing the effects of treatments and to develop novel approaches that will ex psychosocial treatments with specic pharmacological pand the array of treatment options. Additional re edge in this area would help to identify individuals at high search is also needed to provide clinicians with guidance risk for the disorder. Delineation of susceptibility genes in treating patients whose panic symptoms are resistant to for panic disorder (and, potentially, their interaction with initial treatments. For example, studies of specic aug known environmental risk factors for panic disorder such mentation or switching strategies (within and across mo as smoking or childhood maltreatment) could help iden dalities) would make valuable contributions to the tify new potential pathways and mechanisms to target for literature on treatment of panic disorder. More studies of the basic fying effects of medications or psychosocial treatments pathophysiology of panic disorder are needed in order to that predict treatment outcome. Basic and translational research also informs de needed to evaluate long-term effectiveness and relapse pre velopment and renement of psychosocial treatments. In addition, little is known about charac For example, animal studies showing that D-cycloserine teristics of individuals with panic disorder that predict facilitates extinction of conditioned fear have led to re response to any specic treatment. As such, there is a mini search on whether this agent could optimize response to mal evidence base to aid psychiatrists and patients in choos exposure therapy. Recently D-cycloserine was shown to ing among standard treatments for panic disorder based on enhance response to exposure therapy in patients with so patient characteristics. Researchers should continue to cial phobia, and initial work suggests it may demonstrate search for factors that predict positive response and resis Copyright 2010, American Psychiatric Association. However, only a limited number of com identify genes that are associated with response to particular bined treatments have been rigorously investigated. Such studies could aid in the development of studies of combination treatments are needed to clarify the more tailored and effective interventions, bringing the treat potential benets. Developing an evidence base for treating trolled trials and require more systematic investigation to panic disorder in pediatric and geriatric patients is critical. Benzodiazepines are clearly effective for panic treatments for panic disorder in pediatric and geriatric pa disorder, but concerns about their side effects and propensity tients are clearly needed. Additional research is also re for producing physiological dependence constrain their use. Most participants in than 30 years, more research that claries the effects of clinical trials for panic disorder are Caucasian, and inves chronic benzodiazepine use. These lines of research could aid in developing threshold panic disorder can be an impairing condition more targeted, streamlined interventions that lead to requiring treatment, research focused on treatment of this faster and more complete symptom resolution. Investigations of the Panic-focused psychodynamic psychotherapy is a prom relationship of sleep, exercise, and nutrition to panic dis ising psychosocial treatment, with efcacy supported by a order symptoms could be illuminating in this regard, as randomized controlled trial. More research is needed to de psychodynamic psychotherapies would also be of interest.
