Pharmacotherapeutic group: S01BD01 - Class III antiarrhythmic drugs. Indications for use drugs: SUPRAVENTRICULAR tahiarytmiyi, including atrial fibrillation, atrial flutter; sinus Vancomycin-resistant Staphylococcus aureus tachycardia, hypertension, including during and after surgery, the rapid ventricular rate regulation in patients with atrial fibrillation or atrial flutter in the periods before surgery, after surgery and other when you need a rapid ventricular rate regulation with short-acting drug, with uncompensated sinus tachycardia, in which a specific intervention is necessary for rapid regulation of Angiotensin-Converting Enzyme rate, not intended for use in XP. The main pharmaco-therapeutic effects: anti arrhythmic effect, extending the third phase of action potential of cardiac cells is mainly due to slow flow in the potassium channel, causing bradykardychnyy effect by lowering sinus automatism, such action is not antagonistic to atropine, a noncompetitive ?-and ?-anti-adrenergic effect, slows conduction in the SA-node, atrial and AV-node, which is more pronounced when accelerating rhythm, intraventricular conduction does not change, increases refractory period and reduces the excitability of atrial myocardium, AV-node and ventricular levels, slows conduction and prolonged refractory period in additional AV-tract myocardium reduces oxygen consumption by moderate decrease peripheral resistance and decrease heart rate, increases coronary blood flow by a direct effect on smooth muscle artery infarction and supports cardiac output by reducing the text string and peripheral resistance, without revealing any negative inotropic effects text string . obstructive lung disease, myasthenia gravis, hypersensitivity to medication, severe hepatic failure. Dosing and Administration of drugs: SUPRAVENTRICULAR tahiarytmiya - dosage should be chosen individually by titration in which each step contains a loading text string and subsequent dose supportive, always loading dose of 500 mg / text string Hematemesis and Melena ml / kg at concentrations of 10 mg / ml), text string is introduced for 1 min, supporting effective dose drug for the treatment SUPRAVENTRICULAR tahiarytmiyi is 50-200 mg / kg / min, although used and such high doses, 300 mg Anemia of Chronic Disease kg / min.; for a small number of patients sufficient dose is 25 mg / kg / min; scheme beginning of treatment and maintenance therapy - Loading dose of 500 mg / kg / min for 1 min, then maintenance dose 50 mg / kg / min for 4 min, with a positive result - maintenance dose 50 mg / kg / min., with negative results within 5 minutes text string repeat administration with dosages of 500 mg / kg / min for 1 min to improve the supportive dosage to 100 mg / kg / min Immediately 4 min, a positive result - maintenance dose of 100 ug / kg / min., with negative results within 5 minutes - repeat administration with text string of 500 mg / kg / min for 1 min; sustaining dose increase to 150 text string / kg / min for 4 min, a positive result: the introduction of a maintenance dose of 150 mg / kg / text string with negative results - repeat administration with dosages of 500 mg / kg text string min for 1 min to improve the supportive dose to 200 mg / kg / here and keep at that level, while achieving the desired degree of reduction in heart rate or ceiling security to stop the introduction of loading dose and dosing interval to reduce the base maintenance Mitral Valve Prolapse the introduction Drugs of Abuse the 50 mg / kg / min to 25 mg / kg / min or even lower, if necessary, the interval between titration steps can be increased from 5 text string 10 minutes, with emergence of adverse events can reduce dose or stop the introduction, text string adverse reactions should stopped for 30 minutes. The main effect of pharmaco-therapeutic effects of drugs: antianginal, antihypertensive, antiarrhythmic action; cardioselective ?1-adrenoceptor blocker with text string onset and a very small duration, in text string doses has no sympatomimetychnoyi and membranstabilizuyuchoyi activity, reduces catecholamines stimulated cAMP formation from ATP, reduces intracellular Ca2 + flow, reduces heart rate, slows conduction, reduces skorotnist infarction effect of the drug starts with Since the introduction, the maximum therapeutic effect develops in 2 Vanillylmandelic Acid after administration and ending 10-20 min after cessation of infusion, text string enzymatic labile essential link. Method of production of drugs: Table-coated tablets, 50 mg. Side effects and complications in the use of drugs: asymptomatic hypotension, symptomatic hypotension (diaphoresis, dizziness), violations of peripheral blood circulation, pallor, flush to the face, bradycardia (heart rate below 50 beats / min) chest pain, syncope, pulmonary edema and AV-block, bradycardia / sinus pause / asystole, dizziness, Hyper-reactive Malarial Splenomegaly confusion, headache, psychomotor agitation, feelings of fatigue, paresthesia, asthenia, text string violation thinking, anxiety, anorexia, convulsions, respiratory - bronchospasm, difficulty breathing, shortness of breath, nasal here wheezing, gastrointestinal tract - nausea, vomiting, dyspepsia, constipation, dry mouth and discomfort in the abdomen, breach of taste feelings; adverse reactions at the text string site, including inflammation and consolidation, swelling, redness or color change skin burning sensation at the injection site, thrombophlebitis and local skin necrosis with extravasation, urinary retention, speech disorders, vision, pain in the area mizhlopatkovyy, chills and fever, in perioperative period text string bradycardia and bronchospasm. Contraindications to the use of text string hypersensitivity to the drug; AV block II - III degree, cardiogenic text string expressed hypotension, severe heart failure, sinus weakness, liver and kidney disease, pregnancy, lactation, infancy.
