classification of drugs
Medications that are used to expand the vessels, divided into 2 main pharmacological groups. This neurotropic agents, active ingredients which act on the central and peripheral nervous system, stimulating rapid removal spasm and dilation of blood vessels.
The second group - this means myotropic. Drugs in this category affect the operation of the cardiac muscle, which in turn leads to lower blood pressure and expansion of the vessel walls.
The table below shows detailed classification vasodilator drugs and neurotropic myotropic mechanism of action, and also describes their influence on the human body.
Classification of vasodilator medications | The pharmacological properties of drugs |
Means depressing vasomotor centers | Act directly on the walls of blood vessels, preventing their contraction and spasm. They are analeptikami that stimulate the brain centers responsible for the act of breathing and vasomotor function. Belong to the category of neurotropic drugs. |
ganglioplegic | Group vasodilators n-acting anticholinergics which nikotinochuvstvitelnye act directly on receptors in the autonomic ganglia. Medications in this category include a neurotropic group. |
Beta-adrenergic agonist | In pharmacology yet encountered the term - beta adrenostimulyatorov. The structure of this type of drugs include synthetic and natural substances having the property to stimulate the work beta-adrenergic receptors of the nervous system. The consequence of their effect is to extend the walls of the great vessels. |
phosphodiesterase inhibitors | Preparations myotropic spectrum, which dilates blood vessels, improve local and general blood circulation. Showing for use in patients with chronic hypertension. |
sympatholytic | Vasodilators, which contain in their composition purely synthetic substances. After entering the human body have an inhibition transfer process neuronal signaling by the sympathetic nervous system to the organs of the cardiovascular system. |
Means adenosine spectrum of action | Drugs that are classified miotropov. It has the properties of expansion and normalize coronary vessels of the heart muscle. Indicated for use in patients who suffer from vascular spasm of the trunk, resulting from cardiac dysfunction. |
blockers | After the introduction of drugs into the body of the blocking group comes adrenoceptor blockers. Cleared spasm of blood vessels, and their effect is provided by expansion. |
nitrogen donator | Act directly on the heart and the entire cardiovascular system. Contribute to the expansion of the arterial walls, and cerebral circulation improving nutrition. It is indicated for use to people suffering from hypertension and chronic heart disease. |
Calcium channel blockers | Formulations heterogeneous pharmacological groups of active components which contribute to reduce the frequency of contractions of the heart muscle. Due to this, the therapeutic effect of lowering blood pressure occurs and vasodilation. |
Potassium channel openers | This anti-arrhythmic drugs that are used in the presence of heart disease, the main cause spasm of vessels. For example, ventricular fibrillation, atrial fibrillation, tachycardia. |
The above classification categories of drugs that have the effect of expanding the blood vessels, are used in the presence of specific clinical and type of disease.
