Single Dose Pharmacokinetic and Pharmacodynamic Evaluation of Three Different Doses of Zolpidem in Children

Insomnia Clinical Trial

Official title: Single Dose Pharmacokinetic and Pharmacodynamic Evaluation of Three Different Zolpidem Doses in Children Ages 2 to 18 Years of Age

Status Completed

Clinical Trial Summary

This is a multicenter trial to evaluate the single-dose safety, tolerability and pharmacokinetics-pharmacodynamics of Zolpidem in a group of children with sleep disturbances stratified by age and dose.

Clinical Trial Description

The consequences of sleep deprivation to the productivity of the individual and society are extensive. (Most clinicians and patients believe that insomnia becomes a clinical problem requiring therapy when excessive daytime sleepiness impairs cognition and mood, interfering with a patient's performance of functions that require alertness. Chronic sleep deprivation often leads to adverse personal, medical and psychiatric complications, underscoring the common request of patients for treatment by their physician.

With an increasing focus on the problem of sleep deprivation in children of all ages, our appreciation of the scope of the problem is expanding. It is estimated that up to 40 % of infants experience difficulty in settling and frequent nighttime wakings with sleep disturbances including bedtime resistance, delayed onset of sleep, and disruptive night wakings occurring in 25 to 50 % of preschoolers. In school-aged children, parents reported an incidence of bedtime resistance in 15 % of their children.

Very limited data exist describing the pharmacokinetics of zolpidem in pediatrics. Colle and colleagues reported the zolpidem clearance to be 3 times greater in children (n=6) compared to young adults (n=104) though Cmax and AUC values were similar despite a higher zolpidem dose (mg/Kg) in the children. Unfortunately these data raise more questions than they answer regarding zolpidem disposition relative to age and highlight the need to comprehensively determine zolpidem disposition characteristics across a broad age range of pediatric subjects.

In summary, although researchers have been hesitant to include children in drug studies, the data indicate that pediatric sleep disturbance have a negative health impact on children and warrant pharmacologic intervention. Studies to identify the appropriate drug and dosage for children of all ages are essential in addressing this health problem that impacts the child and his/her family. ;
