CNS depressants— What are CNS depressants?


• Non-benzodiazepine sleep
medications, such as zolpidem
(Ambien), eszopiclone
(Lunesta), and zalepon
(Sonata), have a different
chemical structure, but act
on some of the same brain
receptors as benzodiazepines.
They are thought to have
fewer side effects and less
risk of dependence than
benzodiazepines.
• Barbiturates, such as
mephobarbital (Mebaral),
phenobarbital (Luminal
Sodium), and pentobarbital
sodium (Nembutal), are used
less frequently to reduce anxiety
or to help with sleep problems
because of their higher risk
of overdose compared to
benzodiazepines. However,
they are still used in surgical
procedures and for seizure
disorders.
