Kava Kava Potassium Channel Activation + Potassium Channel Modulation Patents

"The antispasmodic effect of aryl-substituted α- pyrones from the kava-root have previously been reported, although it was not known that these effects were due to the property of potassium channel activation. It has now been confirmed that kawain is indeed a potassium channel activating substance. All of the kava pyrones have a bulky aromatic group. It has unexpectedly been found that the substitution of a lower alkyl group for the more bulky aromatic group enhances the potassium channel activation effects of the compounds."

"While the kava pyrones were known to have anti¬ convulsant and anti-spasmodic properties, it was not known that they had potassium channel activation effects, and therefore it would not have been obvious from their known anti-convulsive and anti-spasmodic effect that they could also be used for the treatment of hypertension or the treatment of addiction withdrawal symptoms, or any of the other effects of potassium channel activation which do not involve the anti-convulsant or anti-spasmodic effects of the compounds."

"Kava's action as a voltage-dependent ion channel modulator may be a more important part of its pharmacology than action at any GABA allosteric site. I think the similarity of effect to the benzodiazepines may have lead people to jump to conclusions about its mode of action. In effect, kava acts as a combined sodium and calcium channel blocker, as well as a potentiator of potassium channels."

Potassium Channels and Neurodegenerative Diseases
"The classes of drugs that need to be explored include potassium channel openers of the ATP-sensitive, high-conductance calcium-sensitive, and inward rectifier or leakage types. Selective openers for inward rectifier potassium channels are currently not available, although activation of 5-HT1A receptors results in the induction of an inwardly rectifying potassium current. Potent neuroprotective properties have been described for different 5-HT1A agonists in models of focal and global ischemia. Retigabine, a leakage-current potassium channel opener, has been shown to have neuroprotective effects in animal models of neurodegeneration. Of the currently available potassium channel openers, retigabine and BAY-X-3702 are active at nontoxic doses. Further research is needed to develop selective, well-tolerated potassium channel openers."​

Thanks for all the links and citations. Could you summarise what the core point of it is?

 

Tinnitus isn't mentioned in the post or any of the links.

 

I guess the similarity in stopping the over reactive neurological pathways.

 

Enjoy. Will provide in-depth later.

 

This looks similar to my experience - positive if I'm interpreting correctly.

 

Thanks for the data! Looks like the effect, if any, was inconsistent. I'm looking forward to your in-depth write up.

 

Bump on this. Sounds somewhat promising.

 

How it improved your tinnitus, please? Was the improvement long lasting? Thank you so much!

 

Kava kava can damage your liver, right?

 

Apparently this common knowledge originates from a very unique situation that happened some 20 years ago. You're best off googling it, but in short what I've gathered is pretty much no, it really doesn't.

I bought some of what is supposed to be the good stuff from kalm with kava but I haven't tried it yet.

 

It functions like a light benzo for me - only temporary improvement by reducing intensity somewhat.
