Uitkomstmaten
Primaire uitkomstmaten
Changes in dermal blood flow response to capsaicin application and saline iontophoresis, after propranolol administration.
Achtergrond van het onderzoek
Migraine is one of the top 10 most disabling diseases. Propranolol is a nonselective β-blocker that is primarily used to treat hypertension and there is high-quality evidence that propranolol is also an effective prophylactic drug for migraine headaches. The mechanism of action of propranolol is still unknown. We hope to determine the mechanism by measuring with a laser Doppler scanner the increase in dermal blood flow after stimulation of the afferent nerves of the trigeminal nerve on the forehead. The trigeminal nerve also innervates the dura mater, where the migraine is thought to have its origin. We hypothesized that the propranolol will inhibit the rise of dermal blood flow caused by capsaicin application and saline iontophoresis. This will provide more insight in the action of propranolol, resulting in a better understanding of the pathophysiology of migraine and also in its prophylactic treatment.
Doel van het onderzoek
The administration of propranolol will inhibit the increase in dermal blood flow (DBF) induced by capsaicin application.
Onderzoeksopzet
The volunteers will come twice to Erasmus MC. Each appointment will last an estimated of 150 minutes.
Onderzoeksproduct en/of interventie
The volunteers will need to take a tablet of Propranolol 80mg (which is the normal therapeutic dose)
