Buspirone and diazepam in anxiety: a controlled study.

Area of Science:

• Psychiatry and Pharmacology
• Clinical Psychology

Background:

• Anxiety disorders represent a significant public health concern.
• Buspirone and diazepam are established anxiolytic medications with distinct mechanisms of action.
• Comparative efficacy and side effect profiles require ongoing investigation.

Purpose of the Study:

• To compare the anxiolytic efficacy of buspirone and diazepam against placebo.
• To identify patient characteristics associated with differential treatment response.
• To evaluate the side effect profiles of buspirone and diazepam.

Main Methods:

• A 4-week, double-blind, randomized controlled trial involving 240 anxious patients.
• Patients received either buspirone (81), diazepam (81), or placebo (78).
• Inclusion criteria included specific scores on the Covi and Hamilton Rating Scale for Anxiety.

Main Results:

• 212 patients were evaluable for treatment outcomes.
• Married, well-educated females with positive family adjustment and low depression showed greatest improvement.
• Diazepam demonstrated equal efficacy in males and females, targeting somatic symptoms.
• Buspirone was more effective for cognitive and interpersonal anxiety symptoms.
• Significant differences in side effect profiles were observed between buspirone and diazepam.

Conclusions:

• Both buspirone and diazepam show anxiolytic properties, with differential efficacy for specific symptom clusters.
• Patient demographics and psychological factors may predict treatment response.
• Distinct side effect profiles necessitate careful consideration in clinical practice.
