Abstract

Background Traditional combination strategies of cognitive-behavior therapy plus pharmacotherapy have met with disappointing results for anxiety disorders. Enhancement of cognitive-behavior therapy with d-cycloserine (DCS) pharmacotherapy represents a novel strategy for improving therapeutic learning from cognitive-behavior therapy that remains untested in panic disorder.Method This is a randomized, double-blind, placebo-controlled augmentation trial examining the addition of isolated doses of 50 mg d-cycloserine or pill placebo to brief exposure-based cognitive-behavior therapy. Randomized participants were 31 outpatients meeting DSM-IV criteria for panic disorder with or without agoraphobia, who were offered five sessions of manualized cognitive-behavior therapy emphasizing exposure to feared internal sensations (interoceptive exposure) but also including informational, cognitive, and situational exposure interventions. Doses of study drug were administered 1 hour before cognitive-behavior therapy sessions 3 to 5. The primary outcome measures were the Panic Disorder Severity Scale (PDSS) and Clinicians' Global Impressions of Severity.Results Results indicated large effect sizes for the additive benefit of d-cycloserine augmentation of cognitive-behavior therapy for panic disorder. At posttreatment and 1 month follow-up, participants who received d-cycloserine versus placebo had better outcomes on the PDSS and global severity of disorder and were significantly more likely to have achieved clinically significant change status (77% vs. 33%). There were no significant adverse effects associated with DCS administration.Conclusions This pilot study extends support for the role of d-cycloserine in enhancing therapeutic learning from exposure-based cognitive-behavior therapy and is the first to do so in a protocol emphasizing exposure to feared internal sensations of anxiety in panic disorder.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
