Official Title: CGRP's Cluster Headache Inducing Abilities in Cluster Headache Patients
Brief Summary:
It has previously been shown that nitroglycerine induces cluster headache attacks in episodic cluster headache patients (ECH patients) in bouts but not in remission phase. Furthermore, plasma concentrations of calcitonin gene-related peptide (CGRP) have been shown to be significantly higher during, but not before and after, an attack.
The attack appears around 20-40 min after nitroglycerine infusion with vasodilatation. During this latency period preceding the attack, no increase in CGRP plasma concentrations is seen. CGRP induces migraine attacks in 65% of migraine patients, and CGRP antagonists as well as monoclonal antibodies against CGRP are effective in migraine treatment.
Based on the above the investigators hypothesize the following:
