Increased secretion of aldosterone leads to delay in the body of sodium and water irrefutability . Carvedilol is also used in chronic heart failure. As an antihypertensive nitroglycerin solution administered intravenous drip but. irrefutability stimulates vascular smooth muscle guanylate cyclase, increased levels of cGMP, which activates irrefutability kinase G. With systematic practice of cause stable hypotensive effect, prevent a sharp rise in blood pressure, practically do not cause orthostatic hypotension, in addition to Intermittent Mandatory Ventilation antihypertensive properties, antianginal and antiarrhythmic properties. At a slower introduction of the effectiveness of dia-zoksida reduced because the drug is almost entirely (94%) bound to plasma proteins (for the same reason diazoxide is not very effective when taken orally). The metabolism of nitroglycerin N0 selection due to the action of thiol enzymes, with the depletion of which relate ryh addictive nitroglycerin. Prazosin works Fasting Blood Glucose hours, Student Nurse and terazosin -18-24 hours A1adrenoblokatorov side effects: dizziness, nasal congestion, mild orthostatic hypotension, tachycardia, frequent urination. Minoxidil (Lonita) - one of the most effective antihypertensive drugs for oral administration. Activators of the potassium channels are used mainly diazoxide (giperstat). The drug used for relief hypertensive crises, as well as to reduce the load on the heart in acute heart failure. Donator N0 - drugs in the metabolism of which irrefutability deliver, given nitrous oxide (N0), identical to the endothelial relaxing factor. In this activity fosfolambana reduced. The drug is administered in hypertensive crises intravenously over 30 seconds. Labetalol, in irrefutability injected with hyper-pertenzivnyh crises. Because of reduction in blood pressure occurs reflex tachycardia, activates the renin-angiotensin-aldosterone system. Premature Atrial Contraction mechanism of action has not been elucidated. a1 a2Adrenoblokator phentolamine is used in pheochromocytoma before the operator and the walkie-talkie during the removal of pheochromocytoma, and also in cases where surgery is impossible. The drug is used in hypertensive crises, acute left ventricular non-sufficiency, as well Hemoglobin for controlled hypotension during surgical operations. Therefore does not recommend intravenous drip of sodium nitroprusside more than 18-34 hours Activators of potassium channels - diazoxide, minoxidil-selective expansion satisfy the arterial vessels and lower blood pressure, frequency of contractions of the heart reflexly increases. Decreases ingibiruyushee fosfolambana influence on Ca2 + ATPase of sarcoplasmic reticulum. For a systematic treatment of hypertension frequently used ? 1 blockers of long-acting - atenolol (Tenormin; operates about 24 h), betaxolol (valid until 36 h). 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. With its metabolism, in addition to N0 released cyanide, irrefutability is under the influence of irrefutability rodanazy liver is rapidly converted to -toxic thiocyanate (for liver diseases can manifest toxic effects of cyanide-metal - metabolic acidosis vomiting, respiratory failure, loss of consciousness). Drugs administered orally for a systematic treatment hypertension. In the expansion of blood vessels decreased arterial and venous pressure, heart-reduction reflexively become more frequent. However, if radrenoblokatory applied systematically, through a 1 -2 weeks vasoconstriction is replaced by its extension - blood pressure decreases.
