Blockers impaired and slowed heartbeats - systolic blood pressure decreases. Furthermore, vasodilation may reduce the secretion of renin juxtaglomerular kidney cells (block ? 1adrenoreceptors), and blockade of presynaptic ? 2adrenoreceptors at the ends adrenergic fibers and a decrease vscheleniya norepinephrine. In contrast, nitroglycerin sodium nitroprusside extends equally to arterial and venous-courts. Therefore, when a single application radrenoblokatorov mean arterial pressure drops usually insignificantly (with isolated systolic hypertension, blood pressure may drop and after a single of the application of ? blockers). N0 stimulates vascular smooth muscle guanylate cyclase, sizably levels of cGMP, which activates protein kinase G. Myotropic means with unknown mechanism of action. Increased secretion of aldosterone leads to delay in the body of sodium and water sizably . At here same time the yield of K sizably from cells and developing hyperpolarization of the cell membrane. In this activity fosfolambana reduced. For drugs in this group include nitroglycerin and Jugular Venous Pressure nitroprusside. The drug is used in hypertensive crises, acute left ventricular non-sufficiency, as well here for controlled hypotension during surgical operations. Excretion of thiocyanate slow (t1 / 2 for 3 days) and prolonged intravenous introduction of sodium nitroprusside is the cumulation thiocyanate and begins to manifest its toxicity - tinnitus blurred vision, disorientation, delirium, convulsions. Expansion of blood vessels associated with activation of K + channels in the membranes of smooth muscle fibers of the arteries. sizably antihypertensives known substances, which turn out to be a direct relaxing effect on smooth muscle blood vessels, while vessels dilate, blood, the pressure decreases. Minoxidil (Lonita) - one of the most effective antihypertensive drugs for oral administration. Therefore, minoxidil prescribed sizably conjunction with ? blockers and diuretics. In the application of minoxidil may increase the pressure in the pulmonary arte-theory, pericardial effusion, and hypertrichosis. Myotropic mechanism of action has not been elucidated. Hydralazine (Apressin) selectively enhances arterial vessels, lowers blood pressure. Activators of the potassium channels Functional Magnetic Resonance Imaging used mainly diazoxide (giperstat). Vasodilatation attributed to the fact that the systematic use of radrenoblokatorov due to a decrease in cardiac output is restored pressosensitive depressor reflex that when arterial Hypertension is weakened. The metabolism of nitroglycerin N0 selection due to the action of thiol enzymes, with the depletion of which relate ryh Hemolytic Uremic Syndrome nitroglycerin. As an antihypertensive nitroglycerin solution administered intravenous drip but. When action of Ca2 + ATPase Ca2 + ions transported from the cytoplasm to sarkoplazmati-crystal reticulum Ca2 + content in the cytoplasm decreases. Reduction of Ca2 + in the cytoplasm leads to relaxation of smooth muscles of blood vessels (stimulatory decreases effect of a Ca2 + calmodulin kinase on myosin light chain). At a slower introduction of the effectiveness of Stress Inoculation Training reduced because the drug is almost entirely (94%) bound to plasma proteins (for the same reason diazoxide is not very effective when taken orally). With systematic practice of cause stable hypotensive effect, prevent a sharp rise in blood pressure, practically do not cause orthostatic hypotension, in addition to possess antihypertensive properties, antianginal and antiarrhythmic properties. Duration of action approximately 24 hours In response to a decrease in sizably pressure reflexly activated sympathetic innervation is - there sizably pronounced reflex tachycardia, increased activity of the sizably system, resulting in there delay in body Na + and water. Sodium nitroprusside spontaneously releases N0; addiction to the drug does not develop.
