Zolpidem for persistent vegetative state--a placebo-controlled trial in pediatrics
1Rehabilitation Department, The Children's Hospital at Westmead, Westmead, Sydney, Australia.
This study found zolpidem did not improve responsiveness or cerebral blood flow in children with persistent vegetative states. Zolpidem showed a tendency to reduce responsiveness, indicating no beneficial effect.
Area of Science:
- Neuroscience
- Pharmacology
Background:
- Persistent vegetative state (PVS) is a severe disorder of consciousness.
- Treatments for PVS aim to improve responsiveness and neurological function.
Purpose of the Study:
- To investigate zolpidem's effect on responsiveness and regional cerebral perfusion in children with PVS.
- To assess if zolpidem offers a beneficial effect in PVS patients.
Main Methods:
- Prospective, double-blind, placebo-controlled randomized trial in children with PVS.
- Zolpidem or placebo administered for 4 days, with assessments at baseline and post-treatment.
- Outcomes measured using Rancho scales, coma/near-coma scale, and F(18)-FDG PET scans.
Main Results:
- No significant changes in Rancho scales or F(18)-FDG PET scans observed.
- A trend towards reduced responsiveness was noted with zolpidem compared to placebo.
- Coma/near-coma scale showed a tendency to increase, suggesting reduced responsiveness.
Conclusions:
- Zolpidem did not demonstrate a beneficial effect in children with PVS.
- No evidence of improved responsiveness or increased cerebral blood flow with zolpidem.
- Zolpidem was associated with a tendency towards reduced responsiveness.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
