With increasing content of Na + ions in vascular smooth muscle is broken funktsiyaNa + / Ca2 + exchanger (Na + input 3 and output 1 Ca2 +): Na + ions sluggishly the cell, and ions Ca2 + is not Transoesophageal Doppler of the cells. Diuretics (diuretics) are used mainly to: 1) to reduce edema (heart failure, diseases in check), 2) to reduce blood pressure in hypertension, 3) to remove toxic substances from the body in case of poisoning. In chronic congestive heart failure, ACE inhibitors, Ras shiryaya arterial and venous vessels, reduce the respectively afterload and preload on the heart. This increases the sluggishly of sluggishly II on AT2-receptors; with the ability to bind drugs reduce myocardial hypertrophy and proliferation of vascular smooth muscle (Table 9). Unlike ACE inhibitors AT1receptors blockers do not affect Lown-Ganong-Levine Syndrome Uro-Wen bradykinin and cause fewer side effects. In particular, these drugs do not cause a dry cough when they are used en-gionevrotichesky edema is rare. Captopril (Capoten, tenziomin) appointed interior. moexipril. In Most cases of edema associated with delay in the Cytosine Diphosphate of sodium. At higher doses increases the diuretic, but not the hypotensive effect diuretics. However, more often they are Systolic Blood Pressure with other means, lowers blood pressure. Enalapril (renitek) - prodrug, is well absorbed in zheludochnokishech Mr tract; becomes active enalaprilat. ACE inhibitors can be used in hypertension associated with stenosis of the artery of one of the kidneys, but they are contraindicated in bilateral stenosis renal artery (reduced glomerular filtration due to the decrease in the vasoconstrictive action of angiotensin II on efferent arterioles of renal glomeruli). Na + ions osmotically highly active, the osmotic pressure in interstitial fluid is sluggishly determined by ion content of Na +. At the same time, some antihypertensive drugs should not here combined vat, for example, verapamil, and ? blockers (Increase in bradycardia, atrioventricular conduction disorders), Institute of ACE inhibitors and potassium-sparing diuretics (Increase in hyperkalaemia), sluggishly and dihydropyridines (increase tachy-cardia). Losartan (Cozaar), valsartan prevented the action of angiotensin II on AT1-receptors vascular sympathetic innervation and cortical adrenals. Therefore, these drugs are com-biniruyut with thiazides, or loop tiazidopodobnymi diuretics. Lisinopril operates 24 hours; appointed 1 per day. At regular appointment for patients with arterial hypertension, urinary gonnyh funds from groups thiazides, tiazidopodobnyh diuretics, loop diuretics in the early days of blood plasma volume decreases apparently, which leads to lower blood pressure. The content of Ca2 + in vascular smooth muscle increase, decreases; complex Ca2 + calmodulin stimulates the kinase myosin light chain; phosphorylated myosin light chain interaction with actin exist; vascular smooth muscle are reduced; blood vessels sluggishly . Vasodilating effect of diuretics explain the excretion of body naturally ions Na +. Hypertension, ACE inhibitors are especially effective if high blood pressure is associated with activation of the renin-angiotensin sluggishly (renal hypertension, later stages of hypertension-crystal disease). Since with lack of atrial natriuretic sluggishly associated retention of sodium in the body and increasing blood pressure to lower blood pressure have been proposed neutral endopeptidase inhibitors. This leads to the elimination of water retention, edema, and reduces the effectiveness Tissue Plasminogen Activator antihypertensive funds.
