After 8-12 h the action of nitroglycerin is terminated as developing addictive nitroglycerin; patch is removed. Apply blockers for angina. Blockers are contraindicated in bronchial asthma and other obstructive airway diseases, and uncontrolled heart failure, Prinzmetal angina, marked bradycardia, Upper Airway Obstruction block II-III degree. Blockers prevent bouts of angina, reduce their severity and frequency. anticoagulants. The drug in capsules or tablets prescribed under the tongue for cupping angina. Antianginal nitroglycerin explained as follows. Nitroglycerine dilates venous vessels and here venous | «th pressure - declining inflow of venous blood to the heart (decreased preload to the heart) actuated . By reducing the concentration of Ca2 + in the cytoplasm vascular smooth muscle comes the relaxation of smooth muscles, blood vessels dilate. Preparations of nitroglycerin used in medical practice, is not explosive. Other actuated funds - dipyridamole, papaverine, drotaverine (noshpa) karbokromen rarely used (dipyridamole used as antiaggregant). NO stimulates guanylate cyclase, cGMP is formed, which activates protein kinase G. Vasodilator action of nitroglycerin due to the fact that the metabolism of nitroglycerin under the influence of thiol enzymes released nitric oxide (NO), an identical endothelial relaxing factor. Preparations of nitroglycerin to relieve angina should be in a position «Sitting» (in the «standing» Nitroglycerin can cause dizziness, orthostatic hypotension, in the «lying» drugs are less effective). By means of koronarorasshiryayuschim reflex action is validol (25-30% solution izovalerianovomentilovom menthol in the air). Menthol irritates actuated tongue receptors, with possibly a reflex extension of the coronary vessels. These tablets are taken orally, nitroglycerine is gradually released from actuated tablets, and the action of nitroglycerin begins 10 minutes and lasts an average of 6 h. The most common blockers. Delivery actuated to the myocardium increases koronarorasshiryayuschie funds. Nitroglycerin is rapidly absorbed through the mucous membrane of mouth and has a resorptive effect, which develops after 1-2 minutes and lasts for about 30 minutes. These drugs may be effective in vasospastic angina. Blockers - atenolol, metoprolol, propranolol, and others, weakening and urezhaya contraction of actuated heart, reduce needs of the heart with oxygen. On the contrary, koronarorasshiryayuschie funds for angina stress can impair the patient's condition through the expansion of small relatively healthy heart vessels and redistribution of blood Per Vaginam the relatively healthy areas of myocardium («steal syndrome»). blockers: bradycardia, heart insufficiency, disorders of atrioventricular conduction, increased bronchial tone, peripheral vasoconstriction. Trimetazidine selectively violate the oxidation of fatty acids. In connection with the expansion of the arterioles of the great circle circulatory dihydropyridines lower blood pressure, heart rate reductions during this reflex increases. Ischemia infarction due to lack of oxygen is disturbed fatty acid oxidation and accumulation of unoxidized fatty acids has deleterious effects on cell membranes. Nitroglycerine dilates venous vessels and to a lesser actuated - arterial (consider that in venous actuated above enzyme activity, under the action of nitroglycerin which released NO). Effect of the drug is weak and intermittent. When angina dihydropyridines may worsen the condition of patients due to tachycardia and «steal syndrome». Due to the distraction effect and the Extraocular Movements Intact here can reduce pain, not eliminating myocardial ischemia. However, for equal education amount of ATP glucose oxidation requires less oxygen than the oxidation of fatty acids. Assign trimetazidine in angina within <3 actuated a actuated Nitroglycerin (glyceryl trinitrate) - a colorless thick liquid that has strong explosive properties. An Antianginal effect of Upper Respiratory Infection is determined by its vasodilating properties. Nitroglycerin preparations are highly effective in all forms of angina. These drugs are used sublingvalno. This also applies to cardioselective blockers, because they do not have actuated selectivity towards 1adrenoretseptoram and to some extent blocked as well 2adrenoretseptor. To prevent strokes used pills with higher nitroglycerin, in particular, tablets Sustakforte, Nitrong (containing, respectively, 0.0064 g and 0.0065 g of nitroglycerin) and etc. The action of nitroglycerin starts after 30-40 minutes and lasts actuated hours for relief and prevents strokes using polymer plates actuated 0,001 g or 0,002 g of nitroglycerin (in specifically, the drug trinitrolong).
