Cognitive style, alprazolam plasma levels, and treatment response in panic disorder

Depression and Anxiety, 2008

This study investigated an anxiety-prone cognitive style (measured by the Anxious Thoughts and Tendencies Questionnaire, AT&T) as a predictor of the acute response to increasing alprazolam plasma levels in panic disorder. Panic disorder patients (n 5 26) were treated with escalating doses of alprazolam for 4 weeks, then a fixed dose of 1 mg four times a day for 4 weeks. At 0, 1, 2, 3, 4, 6, and 8 weeks, trough alprazolam plasma levels; clinical, self-report, and performance measures; and vital signs were assessed. Panic attack data were from daily diaries. The repeated response measures were analyzed in relation to alprazolam plasma levels using SAS GENMOD, with patients classified as high or low on the baseline AT&T. Panic attacks, anticipatory anxiety, fear, avoidance, overall agoraphobia, the Hamilton Anxiety Rating Scale, and clinicians' global ratings improved with increasing alprazolam plasma levels. Hopkins Symptom Checklist-90 Anger-Hostility; Profile of Mood States Vigor, Confusion, and Friendliness; and speed and accuracy of performance worsened. Patients with high AT&T scores were worse throughout the study on situational panics, fear, avoidance, overall agoraphobia, the Hamilton Anxiety Rating Scale, the Hamilton Rating Scale for Depression, and Clinical Global Improvement; most Hopkins Symptom Checklist-90 clusters; Profile of Mood States Anxiety, Depression, and Confusion; and Continuous Performance Task omissions. We conclude that in panic disorder: (1) alprazolam has a broad spectrum of clinical activity related to plasma levels in individual patients; (2) sedation, disinhibition, and performance deficits may persist for at least a month after dose escalation ends; (3) marked anxiety-prone cognitions predict more symptoms throughout treatment, but do not modify the response to alprazolam and therefore should not influence the choice of alprazolam as treatment.

Adverse effects associated with the short-term treatment of panic disorder with imipramine, alprazolam or placebo

European Neuropsychopharmacology, 1994

Side effects play a significant role in the selection of drugs to be used in panic disorder/agoraphobia whose polyphobic symptomatology often includes a suspiciousness about taking drugs and a fear of undesired side effects which may lead to the refusal of treatment. The safety, side effects and patients' acceptance of alprazolam and imipramine versus placebo were evaluated in 1168 subjects with panic disorder/agoraphobia who had been enrolled in the second phase of the Upjohn World Wide Panic Study. Side effects that worsened over baseline to a greater extent with alprazolam than with imipramine and placebo were sedation, fatigue/weakness, memory problems, ataxia and slurred speech. In the imipramine group blurred vision, tachycardia/palpitations, insomnia, sleep disturbance, excitement/nervousness, malaise, dizziness/faintness, headache, nausea/vomiting and decrease in appetite were worse than in the other groups. In the placebo group the anxious symptoms were most prominent. The highest level of compliance was shown in the alprazolam-treated group and the lowest in the placebo-treated group. Strong predictors of side effects were not observed. lfa side effect profile is known, it will be easier for a clinician to choose the right drug and the appropriate management by taking into account compliance, safety and efficacy in each patient under treatment. Further information about side effects in long-term maintenance treatment would be of great clinical pertinence in ensuring safety and enhancing patients' quality of life.

Current Pharmacological and Non-Pharmacological Treatments of Panic Disorder/Agoraphobia

Anxiety disorders represent the most prevalent psychiatric disorders, however, many patients who might benefit from treatment are not diagnosed or treated. This may partly be due to lack of awareness of the anxiety disorders by primary care practitioners and by the sufferers themselves. In addition, the stigma still associated with psychiatric disorders and lack of confidence in psychiatric treatments are factors leading to no/under recognition and treatment, or the use of unnecessary or inappropriate treatments. This paper aims to provide a comprehensive review of the pharmacological treatment of panic disorders (PD). The first-line treatments include selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Tricyclic antidepressants (TCAs) are similarly effective, but are less well tolerated than the SSRIs/SNRIs. In treatment-resistant cases, benzodiazepines like alprazolam may be used in patients with no history of dependency and tolerance. Other treatment options include irreversible and reversible monoamine-oxidase inhibitors, hydroxyzine, and others. Atypical antipsychotics may also be effective in resistant cases. Besides pharmacological treatments, some psychological strategies have been shown to be effective, in particular, cognitive behavior therapy (CBT) and other variants of behavior therapy have been sufficiently investigated in controlled studies, and, therefore, will be reviewed herein.

Alprazolam and Exposure for Panic Disorder with Agoraphobia

British Journal of Psychiatry, 1994

Patients with panic disorder plus agoraphobia had 8 weeks of drug treatment (alprazolam or placebo) plus psychological treatment (exposure or relaxation). At the end of treatment at week 8, 40 patients who had become much/very much improved rated how much their gains were attributable to medication or to their own efforts. During the tapering-off to week 16, and treatment-free follow-up to week 43, patients who at week 8 had attributed their gains to medication and felt less confident in coping without tablets had more severe withdrawal symptoms and greater loss of gains than did patients who at week 8 had attributed their gains to their own efforts during treatment. Baseline illness severity, greater age, higher expectations from drug treatment, and more side-effects of drugs during treatment all predicted more external attributions (i.e. to the effect of drugs) but did not independently predict relapse. Patients on alprazolam compared with placebo had more drug attributions. Thoug...

Alprazolam in the treatment of generalized anxiety and panic disorders: A double-blind placebo-controlled study

Psychopharmacology, 1982

In a double-blind controlled study lasting 8 weeks, 50 anxious psychoneurotic outpatients with a primary diagnosis of generalized anxiety or panic disorder were randomly assigned to alprazolam (n = 30), a new benzodiazepine, or placebo (n = 20), after a washout period of 1 week. Alprazolam at dosages between 0.25 and 3 mg/day was found to be significantly better than placebo in the treatment of either disorder. The finding that alprazolam was effective in the treatment of panic disorder is of interest as this diagnostic category is usually treated with tricyclic antidepressants or MAO inhibitors.

Pre-tretment predictors of treatment outcome in panic disorder and agoraphobia treated with alprazolam and exposure

Journal of Affective Disorders, 1994

Pre-treatment predictors of treatment outcome were examined in a group of 144 patients with panic disorder and agoraphobia randomly allocated to alprazolam + exposure (AE), placebo + exposure (PE), alprazolam + relaxation (AR), and placebo + relaxation (PR). First-time psychotropic medication use, severity of agoraphobic disability, and longer duration of illness predicted less global improvement at post-treatment. Pre-treatment severity of agoraphobia predicted less improvement both in the short-and the long-term. Predictors of poorer outcome at 6-month follow-up were older age, past history of depression, severity of phobia targets, and longer duration of illness. Sex, source of referral, pre-treatmerit depression-anxiety-panic, and expectancy from treatment did not relate to outcome.

Alprazolam and exposure for panic disorder with agoraphobia. Attribution of improvement to medication predicts subsequent relapse

Naturalistic manner of benzodiazepine use and cognitive behavioral therapy outcome in panic disorder with agoraphobia

Journal of Anxiety Disorders, 2002

Benzodiazepines (BZs) are commonly used in conjunction with cognitive behavioral therapy (CBT) in the treatment of panic disorder with agoraphobia (PDA). However, empirical evidence provides little support for the utility of this combined treatment approach over CBT alone. Westra and Stewart [Clin. Psychol. Rev. 18 (1998) 307] have proposed that prn or as-needed use of BZs may inhibit positive CBT outcome to a greater extent than regularly scheduled BZ use. Using a naturalistic design, the present study investigated the impact of manner of BZ use on treatment outcome from CBT in 43 patients with PDA. Among various BZ parameters (chronicity, frequency, dose, and frequency of prn use), prn use of BZs for coping with anxiety symptoms was a signi®cant negative predictor of degree of change in both anxiety sensitivity and anxious arousal from pre-to post-CBT. Although no signi®cant between-group differences were evident in pre-treatment symptomatology, unmedicated subjects demonstrated the most positive overall CBToutcome, while prn BZ users evidenced the fewest gains. Regular BZ users were generally not signi®cantly differentiated from unmedicated subjects in CBT outcome and both tended to obtain post-treatment scores in the nonclinical range. Implications of these ®ndings for clinical management of BZ use throughout CBT for PDA are discussed. #

Treatment of panic disorder: recent developments and current status

Expert Review of Neurotherapeutics, 2008

Panic disorder is a commonly encountered condition in general medical practice and in various medical settings. It is important for all medical practitioners to be able to recognize this disorder, provide patients with basic information and medical advice, and depending on the specifi c circumstances, to refer patients for appropriate treatment by primary care physicians, psychiatrists and/or clinical psychologists. This article reviews the developments in the treatment of panic disorder, focusing on the major treatment modalities of pharmacotherapy and cognitive-behavior therapy, as well as their combinations. In addition to providing information on current treatments for panic disorder and the main underlying treatment issues, the article identifi es areas where improvements need to be made and areas where much research has been conducted in recent years. These include simplifi ed modes of delivery of cognitive-behavior therapy, optimal ways of combining medications with cognitive-behavior therapy, and minimizing the risk of recurrence after the cessation of treatment.
