Roles Classification
Biological Roles:
GABA modulator  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.

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.

anticonvulsant  A drug used to prevent seizures or reduce their severity.
anxiolytic drug  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.
