Novostat capsules 10 mg 30 pcs. (Atorvastatin)

Pharmacological action

Synthetic lipid-lowering agent. Atorvastatin is a selective competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), a key enzyme that converts 3-hydroxy-3-methylglutaryl CoA to mevalonate, a precursor to sterols, including cholesterol.

In patients with homozygous and heterozygous familial hypercholesterolemia, non-familial forms of hypercholesterolemia and mixed dyslipidemia, atorvastatin lowers the concentration of total cholesterol (cholesterol), low-density lipoprotein cholesterol (LDL-C) and Apolepop and Apolipop in Apolipop very low density (cholesterol-VLDL) and triglycerides (TG), causes an unstable increase in the concentration of high-density lipoprotein cholesterol (cholesterol-HDL).

Atorvastatin reduces the concentration of cholesterol and lipoproteins in blood plasma by inhibiting HMG-CoA reductase and cholesterol synthesis in the liver and by increasing the number of “liver” LDL receptors on the cell surface, which leads to increased uptake and catabolism of LDL-C.

Atorvastatin reduces the formation of LDL cholesterol and the number of LDL particles, causes a pronounced and persistent increase in LDL receptor activity in combination with favorable qualitative changes in LDL particles, and also reduces the concentration of LDL cholesterol in patients with homozygous familial familial hypercholesterolemia resistant to therapy with other lipid-lowering drugs.

Atorvastatin in doses of 10 mg to 80 mg reduces the concentration of total cholesterol by 30-46%, LDL-C by 41-61%, Apo-B by 34-50% and TG by 14-33%.

The treatment results are similar in patients with heterozygous familial hypercholesterolemia, non-familial forms of hypercholesterolemia and mixed hyperlipidemia, including in patients with type 2 diabetes.

In patients with isolated hypertriglyceridemia, atorvastatin lowers total cholesterol, cholesterol-LDL, cholesterol-VLDL, apo-B and TG and increases the concentration of HDL-cholesterol.

In patients with dysbetalipoproteinemia, atorvastatin lowers the concentration of intermediate-density lipoprotein cholesterol. In patients with type IIa and IIb hyperlipoproteinemia according to Fredrickson, the average value of increasing the concentration of HDL-C during treatment with atorvastatin (10-80 mg) compared with the initial value is 5.1-8.7% and is not dose-dependent. There is a significant dose-dependent decrease in the ratio: total cholesterol / HDL-C and HDL-C / HDL-C are 29-44% and 37-55%, respectively.

Atorvastatin at a dose of 80 mg significantly reduces the risk of developing ischemic complications and mortality by 16% after a 16-week course, and the risk of re-hospitalization for angina pectoris, accompanied by signs of myocardial ischemia, by 26%.

Atorvastatin causes a reduction in the risk of ischemic complications and mortality in patients with different initial LDL-C concentrations, (in patients with myocardial infarction without Q wave and unstable angina, as in men and women, and in patients under the age of 65). A decrease in plasma concentration of LDL-C correlates better with the dose of the drug than with its concentration in the blood plasma.

Atorvastatin at a dose of 10 mg reduces the fatal and non-fatal outcomes of coronary heart disease (CHD) compared with placebo in patients with arterial hypertension with three or more risk factors.

Pharmacokinetics

Absorption

Atorvastatin is rapidly absorbed after oral administration: the time to reach its maximum concentration (TCmax) in blood plasma is 1-2 hours. In women, the maximum concentration of atorvastatin (Cmax) is 20% higher, and the area under the concentration-time curve "(AUC) - 10% lower than men.

The degree of absorption and concentration in blood plasma increase in proportion to the dose. Absolute bioavailability - about 14%, and the systemic bioavailability of the inhibitory activity against HMG-CoA reductase is about 30%. Low systemic bioavailability is due to a presystemic metabolism in the mucous membrane of the gastrointestinal tract and / or during the “primary passage” through the liver.

Eating slightly reduces the speed and degree of absorption of the drug (by 25% and 9%, respectively, as evidenced by the results of the determination of Cmax and AUC), but the decrease in LDL-C is similar to those when taking atorvastatin on an empty stomach. Despite the fact that after taking atorvastatin in the evening, its concentration in the blood plasma is lower (Cmax and AUC, approximately 30%) than after taking in the morning, the decrease in the concentration of LDL-C does not depend on the time of day at which a drug.

Distribution

The average volume of distribution of atorvastatin is about 381 liters. Communication with blood plasma proteins is not less than 98%. The ratio of the content in red blood cells / blood plasma is about 0.25, i.e. atorvastatin does not penetrate red blood cells well.

Metabolism

Atorvastatin is extensively metabolized to form ortho- and para-hydroxylated derivatives and various -oxidation products. In vitro, ortho- and para-hydroxylated metabolites have an inhibitory effect on HMG-CoA reductase, comparable to that of atorvastatin.

An approximately 70% decrease in HMG-CoA reductase activity occurs due to the action of active circulating metabolites. In vitro studies suggest that the liver CYP3A4 isoenzyme plays an important role in the metabolism of atorvastatin. This fact is supported by an increase in the concentration of atorvastatin in blood plasma while taking erythromycin, which is an inhibitor of this isoenzyme.

In vitro studies have also shown that atorvastatin is a weak inhibitor of the CYPZA4 isoenzyme. Atorvastatin does not have a clinically significant effect on the concentration in the blood plasma of terfenadine, which is metabolized mainly by the CYP3A4 isoenzyme, therefore, its significant effect on the pharmacokinetics of other substrates of the CYP3A4 isoenzyme is unlikely.

Excretion of

Atorvastatin and its metabolites are excreted mainly through the intestines with bile after hepatic and / or extrahepatic metabolism (atorvastatin does not undergo severe enterohepatic recirculation). The half-life (T1 / 2) is about 14 hours, Moreover, the inhibitory effect of the drug against HMG-CoA reductase is approximately 70% determined by the activity of circulating metabolites and lasts about 20-30 hours due to their presence. After oral administration, less than 2% of the accepted dose of the drug is found in the urine.

Special patient groups

Elderly patients

Atorvastatin plasma concentrations of patients older than 65 years are higher (Cmax by about 40%, AUC by about 30%) than in adult patients of a young age.

There were no differences in the efficacy and safety of the drug, or achievement of the goals of lipid-lowering therapy in elderly patients compared with the general population.

Children

Studies of the pharmacokinetics of the drug in children have not been conducted.

Insufficiency of renal function

Impaired renal function does not affect plasma atorvastatin concentration or lipid metabolism, therefore dose adjustment is not required in patients with impaired renal function. Atorvastatin is not excreted during hemodialysis due to intense binding to plasma proteins blood.

Lack of liver function

Atorvastatin concentration increases significantly (Cmax about 16 times, AUC about 11 times) in patients with alcoholic cirrhosis (class B according to the Child-Pugh classification).

Special instructions

Before starting therapy with Novostat, the patient must be prescribed a standard hypocholesterol diet, which he must follow during the entire treatment period.

The use of inhibitors of HMG-CoA reductase to reduce the concentration of lipids in the blood can lead to a change in biochemical parameters, reflecting liver function. Liver function should be monitored before starting therapy, 6 weeks, 12 weeks after the start of taking Novostat and after each dose increase, and also periodically, for example, every 6 months.

An increase in the activity of “liver” enzymes in the blood serum can be observed during Novostat therapy.

Patients with increased enzyme activity should be monitored until the enzyme activity returns to normal. In the case of a persistent increase in ALT or ACT activity to a level exceeding more than 3 times VGN, it is recommended to reduce the dose of Novostat or stop treatment.

Novostat should be used with caution in patients who abuse alcohol and / or have liver disease. Active liver disease or a persistent increase in the activity of aminotransferases of unknown origin are a contraindication to the appointment of Novostat.

Treatment with Novostat, like other inhibitors of HMG-CoA reductase, can cause myopathy. The diagnosis of myopathy (muscle pain and weakness, combined with an increase in CPK activity of more than 10 times compared with VGN) should be discussed in patients with common myalgia, muscle soreness or weakness and / or a marked increase in CPK activity.

Patients should be warned that they should immediately inform the doctor about the appearance of unexplained pain or weakness in the muscles if they are accompanied by malaise or fever. Novostat therapy should be discontinued if there is a marked increase in KFK activity or in the presence of confirmed or suspected myopathy.

The risk of myopathy in the treatment of other drugs of this class increased with the simultaneous use of cyclosporine, fibrates, erythromycin, nicotinic acid in lipid lowering doses (more than 1 g / day) or azole antifungal agents. Many of these drugs inhibit the metabolism mediated by cytochrome P4503A4 and / or drug transport. Atorvastatin is biotransformed under the action of the CYP3A4 isoenzyme.

When prescribing Novostat in combination with fibrates, erythromycin, immunosuppressive drugs, azole antifungal agents or nicotinic acid in lipid lowering doses (more than 1 g / day), the expected benefit and risk of treatment should be carefully weighed and patients should be regularly monitored to detect muscle pain or weakness , especially during the first months of treatment and during the period of increasing the dose of any drug. In such situations, periodic determination of CPK activity can be recommended, although such control does not prevent the development of severe myopathy.

When using Novostat, as well as other drugs of this class, cases of rhabdomyolysis with acute renal failure due to myoglobinuria are described. Novostat therapy should be temporarily discontinued or completely discontinued if there are signs of possible myopathy or a risk factor for the development of renal failure due to rhabdomyolysis (for example, severe acute infection, arterial hypotension, serious surgery, trauma, severe metabolic, endocrine and water-electrolyte disturbances and uncontrolled seizures )

Before starting therapy with Novostat, it is necessary to try to achieve control of hypercholesterolemia by adequate diet therapy, increased physical activity, weight loss in patients with obesity and treatment of other conditions. Patients should be warned that they should immediately consult a doctor if unexplained pain or muscle weakness occurs, especially if they are accompanied by malaise or fever.

When using HMG-CoA reductase inhibitors (statins), including atorvastatin, there have been cases of increased glycosylated hemoglobin and fasting plasma glucose concentrations. However, the risk of hyperglycemia is lower than the degree of reduction in the risk of vascular complications with statins.

Influence on the ability to drive vehicles and work with mechanisms

The adverse effects of atorvastatin on the ability to drive vehicles and engage in potential hazardous activities requiring increased concentration and speed of psychomotor reactions were not reported. However, given the possibility of developing dizziness, caution should be exercised when performing the above activities.
