- violation of the autonomic nervous system;
- atherosclerotic plaques, which arise due to a violation of lipid metabolism;
- paroxysmal lesions of arteries;
- aneurysms that appear after trauma, infections, congenital abnormalities of vessel wall vessels, etc .;
- arterial hypertension .
Vasodilator drugs for headaches will help you get rid of discomfort and prevent the dangerous consequences associated with various vascular diseases.
How do vasodilator drugs work?
Vasodilator preparations for the head reduce the tone of the vascular stenochki. It is because of this that the lumen of the vessel increases, and all manifestations of the headache disappear. Depending on the type of active substances, drugs of this group have a direct effect on the smooth muscle of the vesicles, inhibit calcium channels or activate imidazoline receptors. Depending on the mechanism of action, they are divided into three types:
- alpha-nonselective adrenoblockers, hydralazine and slow calcium channel blockers, which have a major effect on arterioles;
- having a predominant effect on venules;
- affecting both arterioles and venules.
In addition, such drugs for the removal of headaches can be antispasmodics, which contribute to lowering blood pressure. All of them also have a miotropic mechanism of action. But in some cases, patients are prescribed sedatives along with them.
