Fig. 1From: Sumatriptan does not change calcitonin gene-related peptide in the cephalic and extracephalic circulation in healthy volunteersCGRP concentration before and after sumatriptan. Mean values (±SEM) of CGRP (pmol/L) in the four vascular compartments, before and after 6 mg subcutaneous sumatriptan. There were no differences between the four compartments at baseline (P = 0.93)Back to article page
