Rat trigeminovascular models: dural protein extravasation, c-fos induction, dural-evoked nociception, dural vasodilation
“In rodent efficacy models, lasmiditan inhibited trigeminovascular protein extravasation (neuroinflammatory response), induction of c-fos, dural-evoked nociception transmission, α-CGRP release, and vasodilation.”
