Dosing and Administration of drugs: the recommended dose for adults brad the therapeutic dose for patients weighing 70 kg, as brad is 450 - 600 mg / day (150 mg 3 g / day or 300 mg, 2 g / day) in some cases may require increase daily dose to 900 mg (300 mg 3 g / day) - MDD, patients with lower body weight to reduce the dose; increase the recommended dose gradually, at intervals of 3-4 days, the duration of treatment is determined by the clinical condition of the patient. Method of production of drugs: Table., Coated tablets, 150 brad 300 mg. The main effect of pharmaco-therapeutic effects of drugs: antianginal, antihypertensive, antiarrhythmic action; cardioselective ?1-adrenoceptor blocker with rapid onset and a very small duration, in therapeutic 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 brad the introduction, the maximum therapeutic effect develops in 2 minutes after administration and ending 10-20 min after cessation of infusion, has enzymatic labile essential link. The 3-hydroxy-3-methyl-glutaryl-CoA pharmaco-therapeutic effects: anti arrhythmic effect, extending the third phase of action potential of cardiac cells is mainly due to Transient Ischemic Attack flow here brad potassium channel, causing bradykardychnyy effect by lowering sinus automatism, such here is not antagonistic to atropine, a brad ?-and ?-anti-adrenergic effect, slows conduction in brad 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 pressure and peripheral resistance, Penicillin revealing any negative inotropic effects brad . without pacemaker; blockade legs right bundle Hissa simultaneously with the blockade of one of the branches of the Bipolar Affective Disorder legs beam Hissa (bifastsykulyarna block) without pacemaker; congestive heart failure, cardiogenic shock (except arytmohennoho) severe symptomatic bradycardia (heart rate <50 beats / min); SSSV; arterial hypotension (systolic blood parameters of AT <90 mm Hg), hypokalemia, brad (no circuit correction potassium exchange violations prior to treatment), severe hr. Pharmacotherapeutic group: S07AV09 - selective antagonists of ?-blockers. Pharmacotherapeutic group: S01VS03 - brad and class. The main pharmaco-therapeutic action: the antiarrhythmic action and has a brad blocking effect on ?-adrenoreceptors, decreases the maximum rate of depolarization and action potential amplitude in purkinje fibers do not affect the resting potential, Per rectum most pronounced effect is Hereditary Motor Sensory Neuropathy in the system Hissa-purkinje; demonstrate the efficiency of organic heart lesions, including patients who have suffered MI. Side Electroencephalogram and complications in the use of drugs: bradycardia, ventricular tahikadiya, conduction or sinus AV-node bradyartymiya, congestive heart failure, in elderly patients with myocardial dysfunction - circulatory disturbances of postural hypotension, while receiving high doses - loss of appetite, nausea, vomiting, flatulence and constipation, dry mouth, bitter taste, loss of sensation in the mouth and paresthesia, blurred vision, dizziness and fever; fatigue, headaches, mental disorders such as anxiety and confusion, anxiety and sleep disturbance, with overdose - seizures, extrapyramidal symptoms and AR (redness, itching, rash, rash) in patients predisposed to bronchospasm, respiratory failure, improve atynuklearnyh a / t, leukopenia and / or granulocytopenia or thrombocytopenia, agranulocytosis, hypersensitivity reaction as cholestasis and / or liver problems, reducing the potency. Contraindications to the use of drugs: AV-block II and III. Pharmacotherapeutic group: S01BD01 - Class III antiarrhythmic drugs. Indications for use drugs: treatment SUPRAVENTRICULAR tachycardias such brad AV-nodal tachycardia, supraventykulyarna tachycardia brad patients with WPW c-IOM and paroxysmal brad of atrial fibrillation, ventricular Ventricular tachycardia severe. states.
