To review the distribution and function of K channels, describe the use of K channels openers in clinical trials and make the case that these channels may play a role in headache and migraine.
K channels are widely present in the trigeminovascular system and play an important role in the regulation of tone in cerebral and meningeal arteries. Clinical trials using synthetic K channel openers report headache as a prevalent-side effect in non-migraine sufferers, indicating that K channel opening may cause headache, possibly due to vascular mechanisms. Whether K channel openers can provoke migraine in migraine sufferers is not known.
We suggest that K channels may play an important role in migraine pathogenesis and could be a potential novel therapeutic anti-migraine target.
回顾钾通道的分布和功能,描述钾通道开放剂在临床试验中的应用,并论证这些通道可能在头痛和偏头痛中发挥作用。
钾通道广泛存在于三叉神经血管系统中,在调节脑动脉和脑膜动脉张力方面发挥重要作用。使用合成钾通道开放剂的临床试验报告称,头痛是非偏头痛患者中普遍存在的副作用,这表明钾通道开放可能会引发头痛,可能是由于血管机制。目前尚不清楚钾通道开放剂是否会诱发偏头痛患者的偏头痛发作。
我们认为钾通道可能在偏头痛发病机制中起重要作用,并且可能是一种潜在的新型抗偏头痛治疗靶点。
