ChEBI

A molecular entity capable of accepting a hydron from a donor (Bronsted acid).

A substance that does not act as agonist or antagonist but does affect the gamma-aminobutyric acid receptor-ionophore complex. GABA-A receptors appear to have at least three allosteric sites at which modulators act: a site at which benzodiazepines act by increasing the opening frequency of gamma-aminobutyric acid-activated chloride channels; a site at which barbiturates act to prolong the duration of channel opening; and a site at which some steroids may act.

Any substance that possesses little anaesthetic effect by itself, but which enhances or potentiates the anaesthetic action of other drugs when given at the same time.

A central nervous system depressant used to induce drowsiness or sleep or to reduce psychological excitement or anxiety.

Anxiolytic drugs are agents that alleviate anxiety, tension, and anxiety disorders, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions.
