OK!!!...We are nearing the 50 pages mark on this thread. God help us if we suddenly have 10 new people on Potiga/Trobalt all reporting in on here! (
Hi Moderators! No doubt you wonderful people will figure out what to do with it).
Anyway, some
great ideas here, and the "Gimme The Drugs Or I'm Gonna Die!" laws/actions, actually sound pretty darn creative in terms of trying for earlier access to AUT00063..."Ask nicely but carry a big stick!", or maybe: "Make him an offer he can't refuse" would be more appropriate?!
OK back to RETIGABINE...and the earlier post that had me puzzling, c/o
@william2 and those two articles listed:

You may recall I was worried about the contradictory aspects of GABA and thus the relationship to Benzo's (one of our most favoured & most hated meds), which many of us take.
Well after some tortuous back-tracking my hunch that the articles were dated appears to be correct. The first is THICK STEW to read. Way beyond my tolerance (maybe gets your groovies going
@jazz and you can handle it, but I can't) though I also don't think necessary for those of us drilling into details.
Again, from that definitive Australian source material there was this on the GABA relationship...
Non KCNQ effects of retigabine
The anticonvulsant activity of retigabine may also involve potentiation of GABAergic inhibitory neurotransmission, although results have been somewhat contradictory. Retigabine (1-10 μM) enhanced GABA mediated currents in primary cortical neurones from fetal rats in vitro, and (at 10-50 μM) dose dependently enhanced monosynaptically evoked inhibitory currents mediated by GABAA activation. However, sponsor studies indicated that retigabine does not appear to interact directly with the GABAA, GABAB, or benzodiazepine receptor binding sites, and did not show agonist, antagonist, or modulatory activity on GABAA α3β3γ2 subunits expressed in HEK293 cells. Retigabine may instead interact with the steroid binding site, since, in the former study, the potentiating effects of GABAergic currents by retigabine and 5-alpha-dihydroprogesterone were not additive. In addition, an allosteric interaction between retigabine and GABA at the picrotoxin site has been demonstrated.
...So I think we can put that concern to rest for now.
Oh and while we are here, as I had gone back to look at stuff, I found it 'refreshing' to remind myself what the hell I was doing - in more descriptive and graphic terms. I figured you too might like these "reminders" of stuff that had not become litter along the side of the road...
There's out little K+ Potassium Gates!!! (Ha, ha...But now I have lost track so far back I can't remember if in T. they got stuck closed, or open?!)...
...Ahhh, yes, c/o that other ancient post and then resurrected via
@111 ...
KCNQ channels are active at the normal cell resting membrane potential (RMP) and contribute a continual hyperpolarizing influence that stabilizes cellular excitability. The Mechanism of action of Retagabine increases the number of KCNQ channels that are open at rest and also primes the cell to retort with a larger, more rapid, and more prolonged response to membrane depolarization or increased neuronal excitability. In this way, Retagabine amplifies this natural inhibitory force in the brain, acting like a brake to prevent the high levels of neuronal action potential burst firing that may accompany sustained depolarizations associated with the initiation and propagation of seizures.
...Then in final de-littering contrition, that old "Synapses for Dummies" link is a great refresher. In case you are hot and bothered and need that waterfall of knowledge to assuage your aching head, here it is again:

OK, I'm heading for my deck and the garden hose with a watering rose on the end. Makes a good 'waterfall'!
