About this trial

The aim of this study is to evaluate the efficacy of hydroxyzine compared to treatment as usual (TAU) for patients with panic disorder. By conducting a pilot study, we hope to provide initial data on the feasibility and potential impact of hydroxyzine for this population. This will inform the design and power calculations of a larger, more comprehensive study in the future.

Objectives:

To assess the feasibility of conducting a randomized controlled trial (RCT) of hydroxyzine for panic disorder.

To evaluate the effectiveness of hydroxyzine compared to TAU in reducing panic symptoms in patients with panic disorder.

To explore the potential side effects and tolerability of hydroxyzine in this population.

Methods:

This will be a single-center, open-label, randomized pilot study. A total of 30 patients with a primary diagnosis of panic disorder will be recruited from a psychiatric outpatient clinic. Participants will be randomly assigned to receive either hydroxyzine or TAU for 8 weeks. The primary outcome measure will be the change in panic symptoms as assessed by the Panic Disorder Severity Scale (PDSS). Secondary outcome measures will include the Hamilton Anxiety Rating Scale (HAM-A) and the Clinical Global Impression-Severity (CGI-S) scale. Participants will be assessed at baseline, 4 weeks, and 8 weeks. Adverse events will be monitored throughout the study.

Expected Results:

This pilot study is expected to provide preliminary data on the feasibility and potential efficacy of hydroxyzine for panic disorder. The results will inform the design of a larger RCT to further evaluate the efficacy of hydroxyzine for this population.

Significance:

There is a need for effective and well-tolerated treatments for panic disorder. If found to be effective, hydroxyzine could provide a new option for patients with this condition, potentially improving their quality of life and functioning. The results of this pilot study will inform the design of future studies and contribute to the development of evidence-based treatments for panic disorder.

Trial outcomes

Primary outcomes

Change in Panic Disorder Severity Scale (PDSS) Mean Score

The primary outcome measure will be the change in panic disorder severity as measured by the PDSS, which will be completed at baseline, week 4, and week 8. The Panic Disorder Severity Scale (PDSS) is a self report scale that measures the severity of panic attacks and panic disorder symptoms. It is appropriate for use with adolescents (13+) and adults. The scale is a useful way of assessing overall panic disorder severity at baseline, and it provides a profile of severity of the different panic disorder symptoms. It is a good monitoring tool because it is brief and sensitive to change, and can be used to track symptoms over time. The scale consists of seven items, each rated on a 5-point scale. The items assess panic frequency, distress during panic, panic-focused anticipatory anxiety, phobic avoidance of situations, phobic avoidance of physical sensations, impairment in work functioning, and impairment in social functioning.

Time frame

8 weeks

Secondary outcomes

Change in Clinical Global Impression Scale (CGI) Mean Score

The secondary outcome measure will be the change in clinical global impression as measured by the CGI, which will be completed at baseline, week 4, and week 8

Time frame

8 weeks
