The standard of care paradigm for migraine treatment has been based almost exclusively on approaches that grew out of the happenstance use of market pharmaceuticals. Only methysergide, which has long since been removed from use for safety concerns, the ergotamine family of drugs, and the triptans were explicitly developed with migraine and other vascular headaches in mind. While the forward and innovative thinking to utilize the broad array of agents to treat migraine served millions well, their therapeutic efficacy was often low, and adverse event profiles were troublesome in the least. Advances in biochemical and molecular biology and the application of advanced "designing drugs" methods have brought about a potentially significant shift in treatment. The gepants have efficacies similar to the triptans but without vascular safety or medication overuse concerns. Preventative gepants offer innovative approaches to prevention and efficacy that exceed even the CGRP monoclonal antibodies. Those monoclonal antibodies brought rapid and highly effective outcomes across the spectrum of migraine. They outpaced older oral medication efficacy and eliminated most adverse events while potentially improving compliance with monthly or quarterly dosing. Other serotonin receptors beyond the 5HT1B and1D receptors have been targeted for decades. They now lead us to better formulations of dihydroergotamine for efficacy, convenience, and tolerability, and a 5HT1F-specific acute treatment like the gepants opens new options for acute management. Neuromodulation goes back to the mid-1800's. Our improved understanding of applied biomedical engineering has brought forward several tantalizing devices, including the application of currents distant from the target and patient regulated. Whether these advances change the paradigm of migraine treatment and standards of care remains to be seen, and issues such as cost and patient acceptance will help mold it.
偏头痛治疗的护理标准模式几乎完全基于因偶然使用市售药物而产生的方法。只有麦角新碱(由于安全问题早已停止使用)、麦角胺类药物以及曲坦类药物是明确针对偏头痛和其他血管性头痛开发的。虽然利用多种药物治疗偏头痛的前瞻性和创新思维使数百万人受益,但它们的治疗效果往往较低,而且不良事件至少也很麻烦。生物化学和分子生物学的进展以及先进的“药物设计”方法的应用带来了治疗方面潜在的重大转变。 gepants类药物的疗效与曲坦类药物相似,但不存在血管安全性或药物过度使用问题。预防性gepants类药物提供了创新的预防方法和疗效,甚至超过了降钙素基因相关肽(CGRP)单克隆抗体。那些单克隆抗体在整个偏头痛范围内都带来了快速且高效的治疗效果。它们超过了旧的口服药物疗效,消除了大多数不良事件,同时可能提高了每月或每季度给药的依从性。除了5HT1B和1D受体之外的其他5-羟色胺受体已经被研究了几十年。它们现在使我们能够获得疗效更好、更方便且耐受性更好的双氢麦角胺制剂,并且一种像gepants类药物那样的5HT1F特异性急性治疗方法为急性治疗开辟了新的选择。神经调节可以追溯到19世纪中叶。我们对应用生物医学工程的深入理解带来了几种诱人的设备,包括应用远离靶点且可调节的电流。这些进展是否会改变偏头痛治疗的模式和护理标准还有待观察,成本和患者接受度等问题将有助于塑造这一模式。
