Clinico-pharmacological group: Lipid-lowering drug.

Pharmacological action

Lipid-lowering drug from the statin group. Selective competitive inhibitor of HMG-CoA reductase enzyme that converts 3-hydroxy-3-metilglyutarilkoenzim And mevalonic acid is a precursor of sterols, including cholesterol. Suppression of cholesterol synthesis (CS) leads to increased reactivity of receptors low density lipoprotein (LDL) cholesterol in the liver and extrahepatic tissues. These receptors bind LDL particles and remove them from the blood plasma, which leads to a reduction in LDL-C levels. Antiatherosclerotic effect of the drug manifests the influence of atorvastatin on the vascular wall and blood components. Atorvastatin inhibits the synthesis of isoprenoids, which are growth factors of the inner shell vessel.

Under the influence of atorvastatin improves endothelial vasodilation. Atorvastatin reduces total cholesterol, LDL cholesterol, apolipoprotein B, triglycerides. Causes an increase in HDL-cholesterol and apolipoprotein A. The action Atorisa develops 2 weeks after starting the drug, the maximum effect is achieved after 4 weeks.

Pharmacokinetics

Suction

After oral administration, is well absorbed from the gastrointestinal tract (80%).

Time to reach Cmax of 1-2 hours due to intensive metabolism in "first pass" through the liver, the bioavailability of atorvastatin is 12%.

Distribution

The average Vd - 381 l binding to plasma proteins - 98%. Atorvastatin does not penetrate the BBB.

Metabolism

Metabolized primarily in the liver under the action of cytochrome P450 3A4 to the formation of pharmacologically active metabolites (ortho-and paragidroksilirovannyh derivatives, products of beta-oxidation). Metabolites have an inhibitory effect on HMG-CoA reductase, which lasts 20-30 hours

Breeding

Derived mainly from the bile (not exposed to pronounced enterohepatic recirculation). T1 / 2 - 14 h. About 46% is excreted in the feces, less than 2% - in the urine.

Pharmacokinetics in special clinical situations

Cmax higher among women by 20%, AUC - below 10%. Cmax in patients with alcoholic cirrhosis is 16 times higher than normal.

Statement
primary hypercholesterolemia;
mixed hyperlipidemia (including patients with insulin-dependent diabetes mellitus);
heterozygous and homozygous familial hypercholesterolemia (as an adjunct to diet).

Dosing regimen

Prior to treatment Atorisom patient should be transferred to a hypolipidemic diet, which must be observed during drug therapy. The drug is taken orally on an empty stomach or after eating. The recommended starting dose - 10 mg daily. Depending on the desired effect, the daily dose can be increased to 80 mg. Atoris taken singly at any time of day, but at the same time every day.

Action Atorisa develops after 2 weeks of taking the drug, the maximum effect is achieved after 4 weeks. Therefore, the dose should not be changed until at least 4 weeks after starting treatment. With primary (heterozygous hereditary and polygenic) hypercholesterolemia (type IIa) and mixed hyperlipidemia (type IIb) treatment begins with an initial dose of 10 mg 1 time per day, which increased after 4 weeks, depending on patient response. The maximum daily dose - 80 mg.

When homozygous hereditary hypercholesterolemia starting dose is 10 mg / day. With a maximum daily dose of 80 mg marked the most optimal effect. Atoris used as adjunctive therapy to other therapies (plasmapheresis) or as a primary method of treatment if the therapy is not possible by other methods. For elderly patients dose adjustment is required.

Patients with liver dysfunction drug is prescribed with caution due to the slowdown Withdrawal from the body. In this situation shows the control of clinical and laboratory parameters and the detection of significant pathological changes in the dose should be reduced or treatment should be discontinued.
