Calcium channel blocker slow II generation, dihydropyridine derivative. It has antihypertensive and antianginal.
Svyazыvayas with dyhydropyrydynovыmy receptors, blocking calcium channels, reduces the transmembrane passage of calcium ions into the cell (mainly in vascular smooth muscle cells, than cardiomyocytes). Antianginal effect is due to expansion of the coronary and peripheral arteries and arterioles. When angina reduces the severity of myocardial ischemia. Expanding peripheral arterioles, reduces peripheral vascular resistance, reduces preload on the heart, reducing myocardial oxygen demand. Expanding the major coronary arteries and arterioles in the unaltered and ischemic areas of the myocardium, increases the supply of oxygen to the myocardium (especially in vasospastic angina). It prevents the development of constriction of the coronary arteries (incl. caused by smoking).
In patients with angina and single daily dose Stamlo® M increases the run-time physical activity, slows the development of angina pectoris and ischemic ST-segment depression, reduces the frequency of angina attacks and consumption of nitrates.
It has a long dose-dependent hypotensive effect. The antihypertensive effect is due to the direct vasodilating effect on vascular smooth muscle. When hypertension single dose provides a clinically significant reduction in blood pressure over 24 no (with the patient lying down and standing up). It does not cause a sharp decline in blood pressure, reducing exercise tolerance, left ventricular ejection fraction. Reduces the degree of left ventricular hypertrophy, It has anti-atherosclerotic and cardioprotective effect in ischemic heart disease. No effect on the myocardial contractility and conductivity, It does not cause a reflex increase in heart rate.
It inhibits platelet aggregation, increases glomerular filtration rate, It has a weak natriuretic effect.
In diabetic nephropathy does not increase the severity of microalbuminuria.
No adverse effects on metabolism and lipid content in the blood plasma.
The therapeutic effect develops after 2-4 no, длительность действия – 24 no.
Absorption
After oral administration of amlodipine is slowly absorbed from the gastrointestinal tract. Receipt time and composition of the food does not affect the degree of absorption of the drug. The absolute bioavailability of 64%. Cmax achieved through 6-9 no. Revealed linear dependence of the content of amlodipine in the blood of the dose Stamlo® M.
Food intake does not alter the bioavailability of amlodipine.
Distribution
Average Vd is 21 l / kg, which indicates, that most of the drug is in the tissues, а относительно меньшая – в крови. Css achieved through 7 days of continuous use of the drug.
Linking blood plasma proteins- 95%. It penetrates through the BBB.
Metabolism
Amlodipine podvergaetsya medlennomu, but extensive metabolism (90%) in the liver into inactive metabolites, подвергается эффекту “первого прохождения” через печень. Metabolites not possess significant pharmacological activity.
Deduction
After a single oral T1/2 It varies between 31 to 48 no, and for re-appointment is about 45 no. In the liver, about biotransformiroetsa 90% amlodipine into inactive metabolites. Report the news: 60% as metabolites, 10% - Unchanged; with feces - 20-25% as metabolites. Provided with breast milk. The total clearance of 0.116 ml / sec / kg (7 ml / min / kg, 0.42 L / h / kg).
Pharmacokinetics in special clinical situations
Elderly patients over 65 s elimination of amlodipine slowed (T1/2 – 65 no) compared to younger patients, However, this difference has no clinical significance.
Patients with hepatic insufficiency is expected elongation T1/2 and assigning prolonged drug accumulation in the body is higher (T1/2 increases to 60 no).
Renal failure does not significantly affect the kinetics of amlodipine.
