Roles Classification
Chemical Role:
environmental contaminant  Any minor or unwanted substance introduced into the environment that can have undesired effects.
Biological Roles:
drug allergen  Any drug which causes the onset of an allergic reaction.
xenobiotic  A xenobiotic (Greek, xenos "foreign"; bios "life") is a compound that is foreign to a living organism. Principal xenobiotics include: drugs, carcinogens and various compounds that have been introduced into the environment by artificial means.
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.
Applications:
sedative  A central nervous system depressant used to induce drowsiness or sleep or to reduce psychological excitement or anxiety.
drug allergen  Any drug which causes the onset of an allergic reaction.
anticonvulsant  A drug used to prevent seizures or reduce their severity.
