Pharmacological action

Atorvastatin is a selective competitive inhibitor of HMG-CoA reductase, an enzyme that determines the limiting rate of cholesterol biosynthesis, responsible for the conversion of 3-hydroxy-3-methyl-glutaryl-coenzyme A to mevalonate, a precursor of sterols, including cholesterol. In the liver, triglycerides and cholesterol are incorporated into very low-density lipoproteins (VLDL), enter the blood plasma and are transported to peripheral tissues. VLDL forms low-density lipoproteins (LDL), which are catabolized primarily through interaction with high-affinity LDL receptors.

 Atorvastatin reduces plasma cholesterol and lipoprotein levels by inhibiting HMG-CoA reductase and cholesterol synthesis in the liver, as well as by increasing the number of “hepatic” LDL receptors on the cell surface, increasing the uptake and catabolism of LDL.

Atorvastatin reduces LDL production and the number of LDL particles. Atorvastatin causes a pronounced and persistent increase in the activity of LDL receptors in combination with favorable changes in the quality of circulating LDL particles.

Dose-dependently reduces LDL levels in patients with homozygous hereditary hypercholesterolemia, resistant to therapy with other lipid-lowering agents. Studies of the dose-effect ratio have shown that atorvastatin reduces the level of total cholesterol (by 30-46%), LDL cholesterol (by 41-61%), apolipoprotein B (by 34-50%) and triglycerides (by 14-33%), while simultaneously causing, to varying degrees, an increase in HDL cholesterol and apolipoprotein A.

These results were similar in patients with heterozygous familial hypercholesterolemia, non-familial forms of hypercholesterolemia, and mixed hyperlipidemia, including patients with non-insulin-dependent diabetes mellitus.

The reduction in total cholesterol, LDL cholesterol, and apolipoprotein B reduces the risk of cardiovascular disease and, consequently, reduces the risk of death. Studies on the effect of atorvastatin on cardiovascular morbidity and mortality have not yet been completed.

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

Indications

• in conjunction with diet to reduce elevated levels of total cholesterol, cholesterol/LDL, and apolipoprotein b and triglycerides and increasing HDL cholesterol in patients with primary hypercholesterolemia, heterozygous familial and non-family hypercholesterolemia and combined (mixed) hyperlipidemia (types IIa and IIb according to Fredrickson);
• in combination with diet for the treatment of patients with elevated serum triglyceride levels (type IV according to Fredrickson) and patients with dysbetalipoproteinemia (type III Fredrickson), whose diet does not provide an adequate effect;
• to reduce levels of total cholesterol and cholesterol/LDL in patients with homozygous familial hypercholesterolemia when diet and other non-pharmacological therapies are not sufficiently effective.

Use during pregnancy and lactation

Atorvastatin is contraindicated for use during pregnancy and lactation (breastfeeding).

It is not known whether Atorvastatin is excreted in breast milk. Taking into account the possibility of adverse events in infants, if it is necessary to use the drug during lactation, the question of stopping breastfeeding should be decided.

Women of reproductive age should use adequate methods of contraception during treatment. Atorvastatin can be prescribed to women of reproductive age only if the probability of pregnancy is very low, and the patient is informed about the possible risk of treatment for the fetus.

Interaction

The risk of myopathy during treatment with other drugs of this class increases with the simultaneous use of cyclosporine, fibrates, erythromycin, antifungal agents related to azoles, and nicotinic acid.

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

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

Plasma concentrations of Atorvastatin decreased by approximately 25% when colestipol was co-administered. However, the lipid-lowering effect of the combination of Atorvastatin and colestipol exceeded that of each drug separately.

When digoxin and Atorvastatin were re-administered at a dose of 10 mg, the steady-state plasma concentrations of digoxin did not change. However, when digoxin was used in combination with Atorvastatin at a dose of 80 mg/day, the digoxin concentration increased by about 20%. Patients receiving digoxin in combination with Atorvastatin should be monitored.

Concomitant use of Atorvastatin and erythromycin (500 mg 4 times / day) or clarithromycin (500 mg 2 times / day), which inhibit cytochrome P4503A4, an increase in the concentration of Atorvastatin in blood plasma was observed.

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

Atorvastatin did not have a clinically significant effect on the plasma concentration of terfenadine, which is mainly metabolized by cytochrome P 450 3 A 4; therefore, it seems unlikely that Atorvastatin can significantly affect the pharmacokinetic parameters of other cytochrome P 450 3 A 4 substrates.

When Atorvastatin was co-administered with an oral contraceptive containing norethindrone and ethinylestradiol, there was a significant increase in the AUC of norethindrone and ethinylestradiol by approximately 30% and 20%, respectively. This effect should be considered 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 reducing 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.

Concomitant use of Atorvastatin 80 mg and amlodipine 10 mg did not alter the pharmacokinetics of Atorvastatin at steady state.

There was no clinically significant adverse interaction between Atorvastatin and antihypertensive agents.

Concomitant use of Atorvastatin with protease inhibitors, known as cytochrome P4503A4 inhibitors, was accompanied by an increase in the concentration of Atorvastatin in blood plasma.

Pharmaceutical incompatibilities are not known.

How to take, course of use and dosage

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 the time of meal. The dose is selected taking into account the initial cholesterol/LDL levels, the purpose of therapy and the individual effect. At the beginning of treatment and/or during an increase in the dose of Atorvastatin, it is necessary to monitor blood lipid levels every 2-4 weeks and adjust the dose accordingly.

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

In most cases, it is sufficient to prescribe a dose of 10 mg of Atorvastatin once a day. 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.

Assign a dose of 80 mg 1 time a day.

The use of the drug in patients with renal insufficiency and kidney diseases does not affect the level of Atorvastatin in blood plasma or the degree of reduction in cholesterol/LDL when it is used, so a change in the dose of the drug is not required.

In case of hepatic insufficiency, the dose should be reduced.

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

Overdose

Treatment: there is no specific antidote, symptomatic therapy is performed. Hemodialysis is ineffective.

Special instructions

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

The use of HMG-CoA reductase inhibitors to reduce blood lipids may lead to changes in biochemical parameters that reflect liver function. Liver function should be monitored before starting therapy,6 weeks,12 weeks after starting Atorvastatin and after each dose increase, as well as periodically, for example, every 6 months. An increase in the activity of “liver” enzymes in the blood serum can be observed during therapy with Atorvastatin. Patients with elevated enzyme levels should be monitored until their enzyme levels return to normal. If the values of alanine aminotransferase (ALT) or asparagine aminotransferase (AST) are more than 3 times higher than the upper permissible 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 a persistent increase in the activity of aminotransferases of unknown origin serve as contraindications to the appointment of Atorvastatin.

Treatment with Atorvastatin may cause myopathy. The diagnosis of myopathy (muscle pain and weakness combined with an increase in creatine phosphokinase (CPK) activity more than 10 times higher than the upper limit of normal) should be discussed in patients with advanced 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. Atorvastatin therapy should be discontinued if there is a marked increase in CKD activity or if there is a confirmed or suspected myopathy. The risk of myopathy associated with other drugs in this class was increased with concomitant use of cyclosporine, fibrates, erythromycin, nicotinic acid, or azole antifungal agents. 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 antifungal agents or nicotinic acid in hypolipidemic doses, the expected benefit and risk 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 the dose of any drug. In such situations, periodic monitoring 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 due to myoglobinuria have been described. Atorvastatin therapy should be temporarily discontinued or completely discontinued if there are signs of possible myopathy or a risk factor for developing renal failure due to rhabdomyolysis (for example, severe acute infection, hypotension, serious surgery, trauma, severe metabolic, endocrine and electrolyte disorders, and uncontrolled seizures).

Before starting therapy with Atorvastatin, it is necessary to try to achieve control of hypercholesterolemia by 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 they are accompanied by malaise or fever.
