New Studies about Zolpidem Tartrate (AMBIEN)

Treatment of patients who suffer from chronic insomnia with Ambien (Zolpidem) showed significantly higher improvement in work performance.

The study was lasting 6 months and treatments were administered from three to seven nights a week. The result was measured by the Work Limitation Questionnaire a self-administrated questionnaire measuring the degree to which health problems interfere with their ability to work.

Patients involved in the study were asked to rate their level of performance on 25 specific job demands by assigning scores ranging from 0 (limitations none of the time) to 100 (limitations all of the time). Work Limitation Questionnaire result was assessed at baseline, 4 and 12 weeks later and at the end of treatment or premature discontinuation.

Worker output assessed the ability to meet demands for quantity and quality of work while completing tasks in a timely manner and time management assessed the ability to meet time demands and cope successfully with scheduling pressures.

"These new data add to the growing body of evidence that shows that the treatment of chronic insomnia can improve next day functioning," said Milton Erma, MD, chief medical officer, Avastra USA, and clinical professor of psychiatry, UCSD School of Medicine.
