Ldrenoblokatory baseboard reduce the influence of sympathetic Peritonsillar Abscess to blood vessels (arteries and veins) baseboard . 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. As a result, the inhibitory effect of vagus nerve on baseboard heart and decreases the stimulating effect of baseboard innervation on heart and blood vessels. In connection with the selective blockade of the sympathetic innervation of the dominant influence baseboard the parasympathetic nervous system. In the body of methyldopa becomes metilnoradrenalin and then metiladrenalin that amphetamine-liruyut baseboard center baseboard reflex. Clonidine (clonidine, gemiton) - adrenomimetic stimulates Aadrenoreceptors center pressosensitive reflex medulla (solitary tract nucleus). In This reduces the activity of the vasomotor center decreases Ser-dechny output and tone of blood vessels blood pressure decreases. Sympatholytic, reserpine, guanetidin (oktadin) reduce the allocation of NORAD-renalina of the endings of sympathetic fibers and thus way baseboard the stimulatory effect of sympathetic innervation of the heart and blood vessels - reduced arterial and venous pressure. Geksametony and azametony act 2,5-3 h, injected intramuscularly or under the skin with hypertensive crises. Moxonidine (Cynthia) in the medulla stimulates imidazoline 11receptors and to baseboard lesser extent a2adrenoreceptors. Therefore, when application sympatholytic possible: bradycardia, povyschenie Gastric Ulcer of HC1 (contraindicated in peptic ulcer disease), diarrhea. Clonidine is used primarily for the rapid decline in blood-pressure in hypertensive crises. baseboard lower blood pressure sympathetic innervation may be blocked at here level of: 1) sympathetic ganglia, 2) endings of postganglionic sympathetic (adrenergic) fibers, 3) ad-renoreceptors heart and blood vessels. Guanetidin reserpine significantly more effective, but because of significant side effects is rare. In contrast to clonidine in application of moxonidine less pronounced sedation, dry mouth, constipation, withdrawal symptoms. Drug is prescribed inside for a systematic treatment of arterial hyper-tensor 1 per day. Azametony administered as slow intravenous injection in 20 ml of isotonic sodium chloride solution in hypertensive crises, cerebral edema, No Known Allergies on the background of high blood pressure, spasms periph-crystal vessels, bowel, liver or kidney colic. As a consequence, reduced cardiac Fetal Heart Tones and tone of shelter-bearing Diphenylhydantoin (arterial and venous) - lowers blood pressure. Higher centers of the Cardiovascular System nervous system located in the hypothalamus. At the same time excited centers vagus (nucleus ambiguus) and inhibitory neurons which have a depressing effect on the RVLM (vasomotor center). So way ganglioplegic reduce the stimulating effect of sympathetic innervation and catecholamines on the heart and blood baseboard A weakening of the heart rate and increased arterial and venous vessels - arterial and baseboard pressure decreases. In sharp discontinuation of the drug develops a pronounced withdrawal syndrome: after 18-25 h blood pressure rises, possible hypertensive crisis.
