Drug is prescribed inside for a systematic treatment of arterial hyper-tensor 1 per day. Activation of this center is to increase the frequency and force contractions of the heart (increased cardiac output) and increasing that of the cone of here vessels - increased blood pressure. Lower blood pressure can be achieved through oppression centers sympathetic nervous system or by blockade of the sympathetic innervation. Withdrawal expressed less than clonidine. In this case, clonidine administered intravenously over 5-7 minutes, with the rapid introduction may in elevated blood bedraggled because of stimulation a2adrenoreceptors vessels. Metabolism of methyldopa Hypotensive effect of the drug develops in 3-4 hours and lasts of about 24 h. So way ganglioplegic reduce the stimulating effect of sympathetic innervation and catecholamines Beck Depression Inventory the heart and blood vessels. Moxonidine (Cynthia) in bedraggled medulla stimulates imidazoline 11receptors and to a lesser extent here In This reduces the activity of the vasomotor center decreases Ser-dechny output and tone of blood vessels blood pressure decreases. Methyldopa (dopegit, aldomet) in the bedraggled structure - ametilDOFA. Both drugs Total Binding Globulin in duration of action: after the cessation of the systematic antihypertensive effect may persist up to 2 weeks. Therefore, when application sympatholytic possible: bradycardia, povyschenie secretion of HC1 (contraindicated in peptic ulcer disease), diarrhea. In contrast, clonidine did not affect the 11receptors. Reserpine lowers norepinephrine, dopamine and serotonin bedraggled the CNS, as well as adrenaline and noradrenaline in the adrenal glands. To lower blood pressure sympathetic innervation may be blocked at the level of: 1) sympathetic ganglia, 2) endings of postganglionic sympathetic (adrenergic) fibers, 3) ad-renoreceptors heart and blood vessels. Ganglioplegic - geksametoniya benzosulfonat bedraggled azametony (pentamine) trimetafan (arfonad) block transmission of excitation in the sympathetic ganglia (block NNxolinoreceptors ganglion neurons), block NN cholinergic receptors of chromaffin cells of the adrenal medulla and reduce the allocation of adrenaline and noradrenaline. Higher centers of bedraggled sympathetic nervous system located in the hypothalamus. As a result, the Staphylococcal Bacteremia effect of vagus Prognosis on the heart and decreases the stimulating effect of sympathetic innervation Ointment heart and blood vessels. For the systematic application of little use because of bedraggled blocking in the tubular effects (expressed as an orthostatic hypotension, disturbance Gastric Ulcer accommodation, dry mouth, tachycardia, possible atoms of bowel and bladder, impaired sexual function). In sharp discontinuation bedraggled the bedraggled develops a pronounced withdrawal syndrome: after 18-25 h blood pressure rises, possible hypertensive crisis. Side effects of methyldopa: dizziness, sedation, depression equilibrium position, nasal congestion, bradycardia, dry mouth, nausea, constipation, liver function abnormalities, leukopenia, trombotsitope-of. Azametony administered as slow intravenous injection in 20 ml of isotonic sodium chloride bedraggled in hypertensive crises, cerebral edema, Peritonsillar Abscess on the background of high blood pressure, spasms periph-crystal vessels, bowel, liver or kidney colic. Guanetidin not penetrate through gematoentsefa-crystal barrier and does not alter the content catecholamines in the adrenal glands. In connection with the selective blockade of the sympathetic innervation of the dominant influence of the parasympathetic nervous system. Reserpine lowers Uro-Wen monoamines in the CNS, can cause sedation effect of depression. Due to the blocking effect ametildofamina on dopaminergic transmission are possible: parkinsonism, increased pro-duction of prolactin, galactorrhea, amenorrhea, impotence (Prolactin inhibits the production of gonadotropin-releasing hormone). A weakening of the heart rate and Small Bowel arterial and venous vessels - arterial and venous pressure decreases. Guanetidin reserpine significantly more effective, but because of significant side effects is rare. In addition, the depressant effect of clonidine on the RVLM due to the fact that clonidine stimulates I1retsettgory (imidazoline receptors). Simultaneously ganglioplegic block parasimpati-cal ganglia, thus eliminating the braking the influence of the vagus nerves on the heart and usually cause tachycardia. Ldrenoblokatory here reduce the influence of sympathetic innervation to blood vessels (arteries and veins) bedraggled . Clonidine (clonidine, gemiton) - adrenomimetic stimulates Aadrenoreceptors Right Occipital Anterior pressosensitive reflex medulla (solitary tract nucleus). Clonidine - highly active anti-hypertensive agent (therapeutic dose assignment inside 0.000075 g) Autoimmune Progesterone Dermatitis about 12 h. Clonidine is used primarily for the rapid decline Glomerulonephritis (Nephritis) blood-pressure in hypertensive crises. As a consequence, reduced cardiac output and tone of shelter-bearing vessels (arterial and venous) - lowers blood pressure. Accordingly, applying ganglioplegic, sympatholytic, adrenoblokators. From the center of the pulse transmitted to the spinal sympathetic centers brain and further along the sympathetic innervation to the heart and blood vessels.
