Indications

Atorvastatin is used:

in combination with diet to reduce elevated levels of total cholesterol, cholesterol/LDL, apolipoprotein B and triglycerides and increase HDL cholesterol in patients with primary hypercholesterolemia, heterozygous familial and non-familial hypercholesterolemia and combined (mixed) hyperlipidemia (Fredrickson types IIa and IIb);

Pharmacological effect

A lipid-lowering drug from the group of statins.

Special instructions

Before starting Atorvastatin therapy, the patient must be prescribed a standard cholesterol-lowering diet, which he must follow during the entire treatment period.

The use of HMG-CoA reductase inhibitors to reduce blood lipid levels can lead to changes in biochemical parameters reflecting liver function. Liver function should be monitored before starting therapy, 6 weeks, 12 weeks after starting Atorvastatin and after each dose increase, and periodically, for example, every 6 months. An increase in the activity of liver enzymes in the blood serum may be observed during therapy with Atorvastatin. Patients who experience elevated enzyme levels should be monitored until enzyme levels return to normal. If alanine aminotransferase (ALT) or aspartic aminotransferase (AST) values ​​are more than 3 times the upper acceptable limit, it is recommended to reduce the dose of Atorvastatin or discontinue treatment.

Atorvastatin should be used with caution in patients who abuse alcohol and/or have liver disease. Active liver disease or persistent increases in aminotransferase activity of unknown origin are contraindications to the use of Atorvastatin.

Treatment with Atorvastatin may cause myopathy. The diagnosis of myopathy (muscle pain and weakness in combination with an increase in creatine phosphokinase (CPK) activity more than 10 times the upper limit of normal) should be considered in patients with widespread myalgia, muscle soreness or weakness, and/or a marked increase in CPK activity. Patients should be warned that they should immediately tell their doctor if they experience unexplained muscle pain or weakness if they are accompanied by malaise or fever.

Atorvastatin therapy should be discontinued in the event of a marked increase in CPK activity or in the presence of confirmed or suspected myopathy. The risk of myopathy during treatment with other drugs in this class was increased with concomitant use of cyclosporine, fibrates, erythromycin, niacin, or azole antifungals. Many of these drugs inhibit cytochrome P450 3A4-mediated metabolism and/or drug transport. Atorvastatin is biotransformed by CYP 3A4.

When prescribing Atorvastatin in combination with fibrates, erythromycin, immunosuppressive agents, azole antifungals or nicotinic acid in lipid-lowering doses, the expected benefits and risks of treatment should be carefully weighed and patients should be regularly monitored for muscle pain or weakness, especially during the first months of treatment and during periods of increasing dosage of any drug. In such situations, periodic determination of CPK activity can be recommended, although such monitoring does not prevent the development of severe myopathy.

When using Atorvastatin, as well as other drugs of this class, cases of rhabdomyolysis with acute renal failure caused by myoglobinuria have been described. Atorvastatin therapy should be temporarily discontinued or completely discontinued if signs of possible myopathy appear or if there is a risk factor for the development of renal failure due to rhabdomyolysis (for example, severe acute infection, hypotension, major surgery, trauma, severe metabolic, endocrine and electrolyte disturbances, and uncontrolled seizures).

Before starting therapy with Atorvastatin, an attempt should be made to control hypercholesterolemia through adequate diet therapy, increased physical activity, weight loss in obese patients, and treatment of other conditions.

Patients should be warned to seek immediate medical attention if they experience unexplained muscle pain or weakness, especially if accompanied by malaise or fever.

Interaction

The risk of myopathy during treatment with other drugs in this class is increased by concomitant use of cyclosporine, fibrates, erythromycin, azole antifungals, and nicotinic acid.

When simultaneous oral administration of Atorvastatin and a suspension containing magnesium and aluminum hydroxide, plasma concentrations of Atorvastatin decreased by approximately 35%, but the degree of reduction in LDL/cholesterol levels did not change.

With simultaneous use, Atorvastatin does not affect the pharmacokinetics of antipyrine (phenazone), so interaction with other drugs metabolized by the same cytochrome isoenzymes is not expected.

With simultaneous use of colestipol, plasma concentrations of Atorvastatin were reduced by approximately 25%. However, the lipid-lowering effect of the combination of Atorvastatin and colestipol was superior to that of each drug alone.

With repeated administration of digoxin and Atorvastatin at a dose of 10 mg, the equilibrium concentrations of digoxin in the blood plasma did not change. However, when using digoxin in combination with Atorvastatin at a dose of 80 mg/day. digoxin concentration increased by approximately 20%. Patients receiving digoxin in combination with Atorvastatin should be monitored.

With the simultaneous use of Atorvastatin and erythromycin (500 mg 4 times / day) or clarithromycin (500 mg 2 times / day), which inhibit cytochrome P450 3A4, an increase in the concentration of Atorvastatin in the blood plasma was observed.

With simultaneous use of Atorvastatin (10 mg 1 time / day) and azithromycin (500 mg 1 time / day), the concentration of Atorvastatin in the blood plasma did not change.

Atorvastatin did not have a clinically significant effect on the plasma concentration of terfenadine, which is metabolized mainly by cytochrome P450 3A4; in this regard, it seems unlikely that Atorvastatin can significantly affect the pharmacokinetic parameters of other cytochrome P450 3A4 substrates.

When atorvastatin was coadministered with an oral contraceptive containing norethindrone and ethinyl estradiol, significant increases in the AUC of norethindrone and ethinyl estradiol by approximately 30% and 20%, respectively, were observed. This effect should be taken into account when choosing an oral contraceptive for a woman receiving Atorvastatin.

Concomitant use with drugs that reduce the concentration of endogenous steroid hormones (including cimetidine, ketoconazole, spironolactone) increases the risk of a decrease in endogenous steroid hormones (caution should be exercised).

When studying the interaction of Atorvastatin with warfarin and cimetidine, no signs of clinically significant interaction were found.

With simultaneous use of Atorvastatin 80 mg and amlodipine 10 mg, the pharmacokinetics of Atorvastatin at steady state did not change.

There were no clinically significant adverse interactions between Atorvastatin and antihypertensive drugs.

The simultaneous use of Atorvastatin with protease inhibitors, known as cytochrome P450 3A4 inhibitors, was accompanied by an increase in the concentration of Atorvastatin in the blood plasma.

No pharmaceutical incompatibilities are known.

Overdose

Treatment: there is no specific antidote; symptomatic therapy is carried out.

Hemodialysis is ineffective.

Recommendations for use

Before prescribing Atorvastatin, the patient should be recommended a standard lipid-lowering diet, which he should continue to follow throughout the entire period of therapy.

The initial dose is on average 10 mg 1 time / day. The dose varies from 10 to 80 mg 1 time/day.

The drug can be taken at any time of the day with food or regardless of meal time. The dose is adjusted based on baseline LDL/C cholesterol levels, goals of therapy, and individual response. At the beginning of treatment and/or during dose increases of Atorvastatin, it is necessary to monitor plasma lipid levels every 2-4 weeks and adjust the dose accordingly.

Primary hypercholesterolemia and mixed hyperlipidemia, as well as Fredrickson types III and IV.

In most cases, a dose of 10 mg of Atorvastatin once a day is sufficient. A significant therapeutic effect is observed after 2 weeks, as a rule, and the maximum therapeutic effect is usually observed after 4 weeks. With long-term treatment, this effect persists.

Homozygous familial hypercholesterolemia.

Prescribed at a dose of 80 mg (4 tablets of 20 mg) 1 time per day.

The use of the drug in patients with renal failure and kidney disease does not affect the level of Atorvastatin in the blood plasma or the degree of reduction in cholesterol/LDL when used, so no change in the dose of the drug is required.

In case of liver failure, the dose must be reduced (see section “With caution” and “Special instructions”).

When using the drug in elderly patients, there were no differences in safety, effectiveness, or achievement of lipid-lowering therapy goals compared to the general population.

Functional features

Absorption is high. The maximum concentration (Cmax) in the blood plasma is achieved after 1-2 hours, Cmax in women is 20% higher, the area under the curve/concentration, time (AUC) is 10% lower; Cmax in patients with alcoholic cirrhosis is 16 times, AUC is 11 times higher than normal.

Food slightly reduces the rate and duration of drug absorption (by 25% and 9%, respectively), but the reduction in LDL cholesterol is similar to that when using Atorvastatin without food. The concentration of Atorvastatin when used in the evening is lower than in the morning (by approximately 30%). A linear relationship was revealed between the degree of absorption and the dose of the drug.

Bioavailability – 12%, systemic bioavailability of inhibitory activity against HMG-CoA reductase – 30%. Low systemic bioavailability is due to first-pass metabolism in the mucous membrane of the gastrointestinal tract and during the “first pass” through the liver.

The average volume of distribution is 381 l, the connection with blood plasma proteins is 98%. Metabolized primarily in the liver under the influence of cytochrome CYP3A4, CYP3A5 and CYP3A7 with the formation of pharmacologically active metabolites (ortho- and parahydroxylated derivatives, beta-oxidation products). In vitro, ortho- and parahydroxylated metabolites have an inhibitory effect on HMG-CoA reductase comparable to that of Atorvastatin. The inhibitory effect of the drug on HMG-CoA reductase is approximately 70% determined by the activity of circulating metabolites.

Excreted in bile after hepatic and/or extrahepatic metabolism (not subject to pronounced enterohepatic recirculation).

The half-life is 14 hours. Inhibitory activity against HMG-CoA reductase lasts for about 20-30 hours due to the presence of active metabolites. Less than 2% of the dose taken orally is determined in the urine. It is not excreted during hemodialysis.

Storage conditions
