Clinical Trials Related to Zolpimist (Zolpidem)
Zolpidem CR and Hospitalized Patients With Dementia [Recruiting]
The purpose of this research study is to compare the effectiveness of Zolpidem CR to that of
placebo in improving sleep efficiency in people with dementia admitted to the hospital
because of their symptoms. You can participate in this study if you have dementia of the
Alzheimer's type or vascular dementia. This study involves placebo; a placebo is a tablet
that looks exactly like Zolpidem CR, the study drug, but contains no active study drug. We
will use placebos to see if the study results are due to the study drug or due to other
reasons. Zolpidem CR is also called Ambien CR and is widely available by prescription.
Zolpidem CR is approved by the U. S. Food and Drug Administration (FDA) for the short-term
treatment of insomnia (trouble falling or staying asleep).
Imaging the Effects of Zolpidem and Alprazolam in Healthy Volunteers at 3T [Recruiting]
The primary goal of this double-blind, placebo-controlled, within-subjects functional
neuroimaging study is to examine the extent to which the hypnotic zolpidem decreases brain
activity in regions of the brain known to process emotional information. Although zolpidem
is an effective sleep-aid, its ability to engender anti-anxiety effects is equivocal, yet
promising. Zolpidem's activity during tasks that engage anxiety-related processes in the
brain will be compared to that of the known anxiolytic drug alprazolam, a positive
comparator caffeine, and placebo. A secondary goal of this study is to compare the
subjective drug effects, or how individuals feel, following the interventions. These
measures will be used to determine the existence of brain-behavior relationships, thus
demonstrating that imaging is an important tool for informing us about how drugs produce
their effects in the brain.
The Role of Partial Reinforcement in the Long Term Management of Insomnia [Recruiting]
The lack of scientific attention devoted to the placebo effect as a phenomenon in its own
right probably reflects the paucity of theoretical positions within which to organize the
existing data and design new research. The proposed investigation 1) is an attempt to
advance from a descriptive to an experimental analysis of the placebo effect, taking into
account classical conditioning effects, and 2) examines the clinical implications of partial
reinforcement as it is applied to the treatment of insomnia. Subjects with primary insomnia
will be treated with zolpidem for a period of one month and then randomized to one of four
groups for a period of 12 weeks: one receiving full dose zolpidem on a nightly basis
(continuous reinforcement), one receiving full dose zolpidem on 14 of 28 nights where
placebo is provided on non-drug nights (partial reinforcement), one receiving full dose
zolpidem on 14 of 28 nights where no pills are imbibed on non-drug nights (intermittent
dosing), and one receiving 5 mg dose zolpidem on a nightly basis (continuous reinforcement
with half the standard dose). Following treatment, subjects will be entered into an
extinction protocol during which they will 1) continue on the schedule assigned during the
experimental period, 2) receive only placebo, or 3) receive neither drug nor placebo. Sleep
and daily functioning will be monitored on a daily basis via sleep diaries for the duration
of the study. It is hypothesized that, holding cumulative dose constant, a partial schedule
of reinforcement will enable patients to better maintain their clinical gains as compared to
subjects that receive either continuous reinforcement with half the standard dose or half
the frequency of use.
Relevance: The proposed research is not an attempt to offer a behavioral alternative to drug
treatment; it is an attempt to acknowledge and capitalize on a behavioral dimension in the
design of drug treatment protocols. The value of the proposed research resides in its
capacity to provide for the long term treatment of insomnia in a manner that increases the
durability of pharmacotherapy while reducing the overall amount of medication required. If
proven effective in the current application, this new approach to pharmacotherapy and
placebo effects is likely to stimulate new interdisciplinary research for the treatment of a
variety of chronic diseases.
The Role of Sleep in the Treatment of Cannabis Use Disorders [Recruiting]
The number of people seeking treatment for marijuana-related problems is on the rise, yet
there is no currently accepted medication proven to help them quit. Frequent marijuana users
have reported that they have trouble sleeping when they try to quit, and that the loss of
sleep can lead to relapse. This research is designed to measure the severity of sleep
problems in people as they are trying to quit heavy use of marijuana, and to investigate
whether extended-release zolpidem (Ambien CRŽ) can improve quit rates among people trying to
stop using marijuana.
Reducing Suicidal Ideation Through Insomnia Treatment [Recruiting]
Epidemiologic reports have linked insomnia to suicidal ideation and suicide death. However,
no studies have determined whether treating insomnia decreases the risk of suicidality. We
have new data indicating that (1) the link between insomnia and suicidal ideation holds true
in clinical trials of depressed insomniacs, (2) dysfunctional cognitions about sleep are
related to suicidal ideas, and (3) treatment of insomnia with hypnotics leads to a reduction
of suicidal ideation. We now propose to test whether cautious use of hypnotics in suicidal,
depressed insomniacs may reduce suicide risk in a multi-site clinical trial.
