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.
