5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Anesthetics, Dissociative

Intravenous anesthetics that induce a state of sedation, immobility, amnesia, and marked analgesia. Subjects may experience a strong feeling of dissociation from the environment. The condition produced is similar to NEUROLEPTANALGESIA, but is brought about by the administration of a single drug. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) (See all compounds classified as Anesthetics, Dissociative.)


Analgesics

Compounds capable of relieving pain without the loss of CONSCIOUSNESS. (See all compounds classified as Analgesics.)


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.)
