In this article, I go in-depth into how Vasodilators work and how they help combat high blood pressure while promoting athletic performance. By Editorial Team. The purpose of this study was to identify the mediators involved in capsaicin-induced vasodilation in the human skin and to evaluate a pharmacodynamic model for the early clinical evaluation of calcitonin gene-related peptide (CGRP) receptor antagonists. In a double-blinded, placebo-controlled, crossover study in 12 healthy volunteers, diameter changes of cranial arteries, occurrence of headache and the parasympathetic system were examined before, during and after a 2-hour continuous . A third line of thinking holds that vasodilation is irrelevant or, at best, 'an innocent bystander' in the pathogenesis of migraine headache. More recently, a two-hour infusion of VIP promoted a long-lasting cranial vasodilation and delayed headache in healthy volunteers, resembling the effect of PACAP27 and PACAP38, two closely related peptides causing migraine. Definition : A headache is a pain or discomfort in the head , scalp , or neck . Recent studies provide evidence that the two headache types are caused by different mechanisms: immediate headaches are connected to vasodilation caused by nitric oxide (NO) release, while migraines are triggered by other actions such as the release of calcitonin gene-related peptide or glutamate, or changes in ion channel function mediated by .

So it is not the dilation but receptor site activation that is important in migraine. Calcitonin gene-related peptide (CGRP) is a potent neuromodulator that is expressed in the trigeminovascular system and is released into the cranial circulation in various primary headaches. Diuretic: Ethanol is a natural diuretic, which means it increases the amount of water and salt . Mainly, it is about caffeine dependency, because headache usually occurs with caffeine withdrawal. CGRP receptor . A 2A - causes coronary artery vasodilation (specific to Lexiscan) Uses a small dose and stimulate a amount A 2A receptor to create hemodynamics changes; Adenoscan(card) requires a higher dose (140 mcg/kg/min) and is less specific, simulating all adenosine receptors . The intensity of the headaches seems to be directly commensurate with dose. However, it has been demonstrated that GTN-induced vasodilation in vivo is independent of the PG system (Ahlner et al., 1991) thus it is unlikely that the COX-2 - PGE 2 pathway has a major role in immediate GTN-induced headaches but its role in delayed migraine-type headaches warrants further studies.
