Intranasal Dexmedetomidine and Zolpidem for Treatment of Primary Insomnia
A Randomized, Placebo-controlled Crossover Trial of Intranasal Dexmedetomidine and Zolpidem for Treatment of Primary Insomnia
Insomnia is a significant public health burden, increasing work absenteeism and health care costs in a large proportion of the population. It causes altered cognition, emotional disturbances, and reduced quality of life. The purpose of this study is to determine whether the sleep promoting effect of dexmedetomidine is superior to the conventional sleep promoting drug, zolpidem.
The main outcome of this study is to measure the time taken to fall asleep. Investigators will also look at incidences of wakening after sleep onset, sleep quality and wake time during sleep.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Sleep onset latency
Time Frame: 720 minutes
|
Sleep onset latency is a measure of how long it takes for the participant to fall asleep once the participant gets into bed.
This will be measured in minutes and reported as minutes for each of the treatments
|
720 minutes
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of wakening after sleep onset; Sleep quality; Wake time during sleep
Time Frame: 720 minutes
|
Incidence of wakening after sleep onset: This is a measure of how many times the participant will wake up after falling asleep. It will be measured as count data. Sleep quality: This is a subjective measure and will be given as a score from a survey completed by the participant. The data will be reported as count data Wake time during sleep: This will be detected with the polysomnography and will be reported in total minutes |
720 minutes
