Combining CGRP mAbs with gepants

Real world data from the United Arab Emirates have underlined the safety and tolerability of combining CGRP mAbs with gepants in patients with migraine in clinical practice. In the retrospective study of 516 patients with episodic or chronic migraine taking CGRP mAbs, 234 were also taking a gepant (rimegepant: 215; ubrogepant 19). During follow up, …

CGRP mAb response predictors in clinical practice

Older patients with migraine and those with migraine-specific clinical features are most likely to be good responders to CGRP mAbs. These are the findings from the largest real world study of CGRP mAb treatment in patients with migraine, with data on a total of 5818 patients in seven European countries. Of the total population, 84.2% …

CGRP antagonists 5 years on – what has been learned?

The site of action of CGRP inhibitors is likely to be in the periphery where the headache begins – in the meninges and possibly trigeminal ganglion. But, when the pain signal from the periphery has been eliminated, there is a secondary, indirect central effect on the excitability of neurones in the cortical, hypothalamic and possibly …
