The Hemodynamics Effect of Glibenclamide on Levcromakalim Assessed by High Resolution Magnetic Resonance Angiography (MRA) Technique in a Randomized Double-blind Cross-over Placebo-controlled Study With Healthy Volunteers

15 healthy participants will randomly be allocated to receive levcromakalim or placebo on to different days before and after oral glibenclamide administration. The aim of the study is to investigate the effect of levcromakalim/placebo infusion on cranial arteries before and after glibenclamide administration. Repeated magnetic resonance angiography (MRA) measurements covering the middle meningeal artery (MMA), superficial temporal artery (STA) and middle cerebral artery (MCA) before and after glibenclamide administration and levcromakalim/placebo infusion.
