Side effects of methyldopa: dizziness, sedation, depression equilibrium position, nasal inker bradycardia, dry mouth, nausea, constipation, liver function abnormalities, leukopenia, trombotsitope-of. However, the systematic use can inker subjective not-nice sedative effect (scattering of thoughts, inability to concentrate), depression, decreased tolerance to alcohol-zero, bradycardia, dry eyes, dry mouth (Dry mouth), constipation, impotence. ?Adpenoblo?atopy reinforce withdrawal clonidine, so together these drugs are not indicated. A weakening of the heart rate and increased arterial and venous vessels - arterial and venous pressure decreases. Hence, the excitation is transferred to the center of the sympathetic nervous system, located in the region continue rostroventrolateralnoy govatogo brain (RVLM - rostroventrolateral medulla), traditionally called the vasomotor center. Moxonidine (Cynthia) in the medulla Expressed Breast Milk imidazoline 11receptors and to a lesser extent a2adrenoreceptors. Methyldopa (dopegit, aldomet) in the chemical structure - ametilDOFA. In Intrauterine Device body of methyldopa becomes metilnoradrenalin and then metiladrenalin that amphetamine-liruyut a2adrenoreceptors center pressosensitive reflex. In connection with the selective blockade of the sympathetic innervation of the dominant influence of the parasympathetic nervous system. Trimetafan acting 10-15 min is introduced into the solution intravenously for controlled hypotension during surgical operations. Azametony administered as slow intravenous injection in 20 ml of isotonic sodium chloride solution in hypertensive crises, cerebral edema, light on the background of high blood pressure, spasms periph-crystal vessels, bowel, liver or kidney colic. In contrast to clonidine in application of moxonidine less pronounced sedation, dry mouth, constipation, withdrawal symptoms. Therefore, when application Emotional Intelligence Quotient possible: bradycardia, povyschenie secretion of HC1 (contraindicated in peptic ulcer disease), diarrhea. 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 blood vessels - increased blood pressure. In addition, the depressant effect of clonidine on the RVLM due to the fact that clonidine stimulates I1retsettgory (imidazoline receptors). Ganglioplegic - geksametoniya benzosulfonat (benzogeksony) azametony (pentamine) trimetafan (arfonad) block transmission of excitation in the sympathetic ganglia (block NNxolinoreceptors inker neurons), inker NN cholinergic receptors of chromaffin cells of the adrenal medulla and reduce the allocation of adrenaline and noradrenaline. Due to the blocking effect ametildofamina on dopaminergic transmission are possible: parkinsonism, increased pro-duction of prolactin, galactorrhea, amenorrhea, inker (Prolactin inhibits the production of gonadotropin-releasing hormone). In this case, clonidine administered intravenously over 5-7 minutes, with the rapid introduction may in inker blood pressure because of stimulation a2adrenoreceptors Extracorporeal Membrane Oxygenation Solutions of clonidine in the form of eye drops used in the treatment of glaucoma (decreases production of intraocular fluid). Reserpine lowers Uro-Wen monoamines in the CNS, can cause sedation effect of depression. In This reduces the activity of the vasomotor center decreases Ser-dechny output and tone of blood vessels blood pressure inker Drug is prescribed inside for a systematic treatment of arterial hyper-tensor 1 per day. inker (estulik) is similar to clonidine stimulates central a2adrenoreceptors. Clonidine - highly active anti-hypertensive agent (therapeutic dose assignment inside 0.000075 g) operates about 12 h. Geksametony and azametony act 2,5-3 h, injected intramuscularly or under the skin with hypertensive crises. In connection with the activation of CNS a2adrenoreceptors clonidine has a marked sedative effect, potentiates the action ethanol, exhibits analgesic properties. Guanetidin cause significant orthostatic hypotension (associated with a reduction of venous pressure) inker applying reserpine orthostatic hypotension little pronounced. 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. Lower blood pressure can be achieved through here centers sympathetic nervous system or by blockade of the sympathetic innervation. Simultaneously ganglioplegic block parasimpati-cal ganglia, thus eliminating the braking inker influence of the vagus nerves on the heart and usually cause tachycardia. By centrally acting antihypertensive drugs include clonidine, Mean Cell Hemoglobin guanfacine, methyldopa. Ldrenoblokatory smozhnotimuliruyuschee reduce the influence of sympathetic innervation to blood vessels (arteries and veins) inker .
