4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Anticonvulsants

Drugs used to prevent SEIZURES or reduce their severity. (See all compounds classified as Anticonvulsants.)


Cytochrome P-450 CYP2B6 Inducers

Drugs and compounds that induce the synthesis of CYTOCHROME P-450 CYP2B6. (See all compounds classified as Cytochrome P-450 CYP2B6 Inducers.)


Cytochrome P-450 CYP3A Inducers

Drugs and compounds that induce the synthesis of CYTOCHROME P-450 CYP3A. (See all compounds classified as Cytochrome P-450 CYP3A Inducers.)


Excitatory Amino Acid Antagonists

Drugs that bind to but do not activate excitatory amino acid receptors, thereby blocking the actions of agonists. (See all compounds classified as Excitatory Amino Acid Antagonists.)


GABA Modulators

Substances that do not act as agonists or antagonists but do affect the GAMMA-AMINOBUTYRIC ACID receptor-ionophore complex. GABA-A receptors (RECEPTORS, GABA-A) 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. GENERAL ANESTHETICS probably act at least partly by potentiating GABAergic responses, but they are not included here. (See all compounds classified as GABA Modulators.)


Hypnotics and Sedatives

Drugs used to induce drowsiness or sleep or to reduce psychological excitement or anxiety. (See all compounds classified as Hypnotics and Sedatives.)
