GABAA receptor subtype involvement in addictive

GABA A receptors form the major class of inhibitory neurotransmitter receptors in the mammalian brain This review sets out to summarize the evidence that variations in genes encoding GABA A receptor isoforms are associated with aspects of addictive behaviour in humans while animal models of addictive behaviour also implicate certain subtypes of GABA A receptor

GABA Receptors

B to differentiate it from the more familiar receptor type which became known as GABA A 4 5 Another bicuculline-insensitive receptor was first identified using the conformationally restricted GABA analog CACA6 7 (Figure 1) This receptor previously termed GABA C has now been subsumed into the GABA A receptor class on the recommendation of the

What is baclofen and how does it work in alcohol

The GABA-A receptor is very well known its structure was elucidated in 1988 by cloning It's the receptor on which benzodiazepines and barbiturates act It is also the site where alcohol acts the GABA-A receptor being one of the most important targets of alcohol in the brain But the GABA-B receptor is very different from the GABA-A

Baclofen Alcohol Relationship

Alcohol – Stimulates GABA-A and GABA-B receptors Benzodiazepines – Stimulates mainly GABA-A receptors Baclofen – Stimulates mainly GABA-B receptors Baclofen is structurally very similar to phenibut another GABA-B receptor agonist which is available in the U S as a supplement The only difference is that baclofen contains a chlorine atom What really makes baclofen

GABA A receptors

Receptors formed from ρ-subunits because of their distinctive pharmacology that includes insensitivity to bicuculline benzodiazepines and barbiturates have sometimes been termed GABA C receptors but they are classified as GABA A receptors by NC-IUPHAR on the basis of structural and functional criteria [4 41-42]

GABA

02 08 2008Does either of these neurotransmitters have more of a control on the brain than the other? If you abuse and down-regulate receptors of either one which is most detrimental? I am thinking GABA-A because alcohol is the only drug that you have a real chance of dying from withdrawal I know GABA-A

Neuropharmacology of alcohol addiction

Pharmacological manipulations of GABA A receptors were studied in alcohol‐preferring rat lines Thus negative allosteric modulators of the GABA A receptor were shown to reduce alcohol consumption in several alcohol‐preferring rat lines (Rassnick et al 1993a Wegelius et al 1994)

whats the difference between gaba A and B? :

(Alcohol benzos) Gaba B is less fucky-uppy causes less muscle relaxation (though still causes it) is more clear headed can cause drowsiness but not so much total sedation like with some of the above drugs and promotes healthy sleep Also causes a more natural feeling reduction in anxiety (Phenibut pregabalin gabapentin) Also note that higher doses of gaba B agonists can lead to gaba A

Favorite GABA(A/B) agonist/antagonist

For me it would have to be alcohol simply because I try not to self medicate anxiety so when I'm using them it's to get fucked up Alcohol does that best IMO and it's also more euphoric (even if not by much) that the benzos I've used which are the only 2 GABA drugs I've used If I just wanna relax there's weed and opiates
