BARBITUATES

Amobarbital Phenobarbital Pentobarbital Malonic Acid Urea Barbituric Acid Barbiturates potentiate the effect of GABA at the GABA-A receptor The GABA-A receptor is a ligand gated ion channel membrane receptor that allows for the flow of Cl through the membrane in neurons GABA is the principle neurotransmitter for this receptor which upon binding causes the channel to open and

WikiZero

A GABA receptor agonist is a drug that is an agonist for one or more of the GABA receptors producing typically sedative effects and may also cause other effects such as anxiolytic anticonvulsant and muscle relaxant effects There are three receptors of the gamma-aminobutyric acid The two receptors GABA-α and GABA-ρ are ion channels that are permeable to chloride ions which reduces

Ionotropic Receptor

Most of these drugs potentiate the effects of GABA on these receptors Barbiturates such as secobarbital phenobarbital etc act on GABA A receptor and increase the duration of open Cl – channel Benzodiazepines used to relieve anxiety and insomnia also act on GABA A receptor and increase the frequency of opening of Cl – channels

phenobarbital — Medical Terminology DB

Phenobarbital binds to and activates the gamma-aminobutyric acid (GABA)-A receptor thereby mimicking the inhibitory actions of GABA in the brain The activation effects of the phenobarbital-receptor-ionophore complex include increased frequency of chloride channel openings membrane hyperpolarization and ultimately synaptic inhibition and decreased neuronal excitability In addition

Phenobarbital

Phenobarbital a gamma-amino butyric acid receptor agonist the receptors are directly activated by phenobarbital and do not require the presence of GABA but phenobarbital will also potentiate the effect of GABA (see Chapter 20) The action of primidone is due in part to its conversion to phenobarbital Primidone has no advantage over phenobarbital and is generally less well tolerated
