Potassium channels induce migrainesActivation of ATP-sensitive potassium channels triggers migraine attacks independent of calcitonin gene-related peptide receptors: a randomized placebo-controlled trial.
We explored the question of whether levcromakalim, a potassium channel opener, can induce migraine attacks in individuals already treated with erenumab, a CGRP receptor antibody. In a double-blind, placebo-controlled study, participants received injections of both levcromakalim and placebo to compare their effects on migraine frequency.
Our findings revealed that levcromakalim led to significantly more migraine attacks within 12 hours compared to placebo, with 88% of participants experiencing attacks after the potassium infusion. This suggests that potassium channels can trigger migraines independently of CGRP activation.

Exploring TRESK's impact on migraineTRESK channel activation ameliorates migraine-like pain via modulation of CGRP release from the trigeminovascular system and meningeal mast cells in experimental migraine models.
We examined how TRESK potassium channels could play a role in managing migraine pain. Using both in-vivo and ex-vivo rat models, we tested different activation methods and found that cloxyquin, a TRESK activator, significantly reduced pain and the associated chemical markers linked to migraines.
Although combining it with sumatriptan showed promising results in lab settings, this didn't translate to the animal models. Our findings suggest that targeting TRESK channels might be a viable method for alleviating migraine symptoms.

Potassium channels may impact headachesHypersensitivity to opening of ATP-sensitive potassium channels in post-traumatic headache.
We conducted a thorough investigation into whether levcromakalim, a potassium channel opener, can trigger migraine-like headaches in individuals suffering from persistent post-traumatic headaches.
In our randomized, double-blind study with a placebo group, we found that 57% of participants experienced such headaches after receiving levcromakalim, compared to only 14% after the placebo.
This suggests that potassium channels may play a significant role in the nature of these headaches and indicates that K channel blockers could be a promising area for future treatments.

Study on BK channels and headachesHypersensitivity to BK channel opening in persistent post-traumatic headache.
We investigated whether the drug MaxiPost, which opens large conductance calcium-activated potassium channels, can trigger migraine-like headaches in adults with persistent post-traumatic headache (PPTH) after mild brain injuries.
In a randomized double-blind trial, participants received either MaxiPost or a placebo, with sessions spaced a week apart to prevent bias.
Our findings suggest that activating these potassium channels can indeed induce migraine-like symptoms, paving the way for potential new treatments. However, further research is needed for solid conclusions about using BK channel blockers for PPTH.
