New migraine medications could endanger patients with high blood pressure

New migraine medications block αCGRP, a neuropeptide which causes vasodilation, for example in the meninges. The very same peptide, which is formed in the muscles during physical activity, protects the heart—which is vital for people with chronic high blood pressure. The innovative migraine prophylaxis could endanger these people, as researchers at the University of Zurich have demonstrated in mice. The […]
