Effects of zolpidem, a short acting non benzodiazepine hypnotic, have been studied in eight female poor sleepers, aged 25 to 54 years, documented during two consecutive adaptation nights. Subjects were recorded according to a 22 day single blind study. Placebo was given orally at bedtime on nights 2-4, zolpidem on nights 5-20 and finally placebo on nights 21-22. Polygraphic recordings (conventional analysis) were performed on nights 1-6; 12, 13; 19-22. Parameters of sleep continuity, sleep architecture and cyclical structure of sleep were studied. Zolpidem 10 mg showed a hypnotic effect on poor sleepers. It reduced sleep latency, increased total sleep time and decreased the number of awakenings during all recorded nights. During the first post-drug night a rebound insomnia was observed in two subjects only. Zolpidem did not increase specifically stage 2 to the detriment of stages 3 and 4 but it restored them during the first nights of administration. Study of the rapid eye movements-non rapid eye movements (REM-NREM) sleep cycles structure showed that the increase of stages 3 and 4 occurred only during the first part of the night. Finally, zolpidem had no effect on REM sleep temporal distribution.

All the mood altering drugs appear to profoundly alter REM sleep By such as the benzodiazepines and Z-drugs (e.g., Zolpidem/Ambien;.

How is the timecourse of REM suppression related to symptom remission in patients with depression who are taking SSRIs?

Alcohol too is associated with REM suppression during the intoxicated state and profound REM dis-inhibition during the withdrawal state. In extreme cases REM makes up 100% of sleep and becomes so disorganized during alcohol withdrawal that the patient suffers delirium tremens. Here the patient appears to be in extreme fear and is persistently hallucinatory. "DTs" are one of the most horrifying things I have ever witnessed a patient undergo.

The FDA recently warned physicians who prescribe Ambien or any other drugs with zolpidem, that their dosage should be decreased as the.

An investigative study was done on the effects of Ambien eight hours after taking the pill. It was discovered that 15 % of women and at least 3 % of men who took only 10 milligrams of Ambien still experienced adverse side effects of the drug as shown in laboratory studies and driving simulators. The problem was even more evident among the group of participants who took 12.5 milligrams of Ambien (a dose suggested as the standard for the extended-release). In the latter group, the statistics suggested that 1 in every 3 women would experience high concentrations of zolpidem in their blood, while the ratio among men was 1 in every 4.

They enter non-REM sleep first, moving gradually from light sleep (Stage 1) to deep sleep.. Eszopiclone (Lunesta), zaleplon (Sonata), zolpidem (Ambien).

After about 45 to 60 minutes, sleep shifts into its REM phase. Although the eyes remain closed, they move rapidly in all directions. In contrast, the limb muscles are compley limp and immobile. Breathing is very slow and may even pause briefly. But the brain is turned on; dreaming occurs only during REM sleep. Although the body is entirely relaxed, the heart rate and blood pressure fluctuate from low to high; the heart pumps less blood to the body but more to the brain. The sympathetic nervous system is active, stimulating production of adrenaline, the “stress hormone.” Most men develop penile erections during REM sleep.

Since there is no “normal” amount of sleep, a diagnosis of insomnia does not depend on the number of hours a person sleeps.
