Angiotensin II receptor blockers: a new possible treatment for chronic migraine?
The objective is to suggest a possible role of different angiotensin receptor blockers in the treatment of chronic migraine, especially in hypertensive subjects. Chronic migraine is a highly disabling disorder affecting between 1.4 and 2.2 % of the general population. Despite many pharmacological and non-pharmacological treatments proposed, the results are rather discouraging. Therefore, we believe that should be highlighted all the possible therapies that may lead to an improvement of the symptomatology. Particularly, data available on efficacy of ARBs in preventing chronic migraine are poor. Methods include case reports, literature review and discussion. We report three cases recently treated with angiotensin II receptor blockers that showed a significant improvement, never previously presented with more conventional treatments, including beta blockers. In all three cases, we obtained the reversibility from a chronic migraine to an episodic. Taking a cue from this observation, we consider desirable large controlled, randomized trials to assess the effectiveness of ARBs both in CM hypertensive patients and in patients who do not require anti-hypertensive therapy; furthermore are desirable comparative studies between the various ARB inhibitors to assay any intermolecular differences in efficacy.
