Impaired renal function
In patients receiving high doses of rosuvastatin (in particular 40 mg / day) tubular proteinuria was observed, which was detected with the help of test strips and in most cases was periodic or short-term. Such proteinuria does not indicate an acute or progressive comorbid kidney disease. The frequency of serious renal dysfunction, noted in the postmarketing study rosuvastatin, higher when taking a dose of 40 mg / day.In patients taking the drug Roxer ® at a dose of 30 or 40 mg / day, it is recommended to monitor the indicators of kidney function during treatment (at least every 3 months).
Influence on the musculoskeletal system
When using rosuvastatin in all doses, but in particular at doses exceeding 20 mg / day, the following effects on the locomotor apparatus were reported: myalgia, myopathy, in rare cases rhabdomyolysis. Very rare cases of rhabdomyolysis with simultaneous application of HMG-CoA reductase inhibitors and ezetimibe have been noted. This combination should be used with caution, since pharmacodynamic interaction can not be ruled out. As in the case of other HMG-CoA reductase inhibitors, the frequency of rhabdomyolysis during post-marketing use of the drug Roxer® is higher with a dose of 40 mg / day.
Determination of CKK activity
The activity of CK can not be determined after intensive physical exertion and in the presence of other possible causes of an increase in its activity; this can lead to incorrect interpretation of the results. If the initial activity of CK is significantly exceeded (5 times higher than the upper limit of the norm), after 5-7 days, a second analysis should be carried out.Do not start therapy if the results of repeated analysis confirm the initial high activity of CK (more than 5 times the upper limit of the norm).
Before starting therapy
Depending on the daily dose, the Roxer® drug should be given with caution to patients with existing risk factors for myopathy / rhabdomyolysis or drug use contraindicated (cm. sections "Contraindications" and "C" caution ").
Such factors include:
- impaired renal function;
- hypothyroidism;
- muscle diseases in the anamnesis (including in the family);
- myotoxic phenomena when taking other inhibitors of HMG-CoA reductase or fibrates in anamnesis;
- excessive use of alcohol;
- age over 65;
- conditions in which the concentration of rosuvastatin in the blood plasma may increase;
- simultaneous application of fibrates.
These patients need to assess the risk and possible benefits of therapy. Clinical monitoring is also recommended. If the initial activity of CK is more than 5 times higher than the upper limit of the norm, therapy with Roxer® can not be started.
During the period of drug therapy
The patient should be informed of the need to report immediately to the doctor in the event of an unexpected occurrence of muscle pain, muscle weakness or spasms, especially in combination with malaise and fever. In such patients, the activity of CK should be determined. Therapy should be discontinued if the activity of CK is significantly increased (more than 5 times compared with the upper limit of the norm) or if the symptoms from the muscles are pronounced and cause daily discomfort (even if the activity of CK is no more than 5 times higher than the upper limit norms). If symptoms disappear and CPK activity returns to normal, consideration should be given to resuming the use of Roxer® or other HMG-CoA reductase inhibitors in smaller doses with careful medical supervision. Control of the activity of CKK in the absence of symptoms is inexpedient. Very rare cases of immuno-mediated necrotizing myopathy with clinical manifestations in the form of persistent weakness of proximal muscles and increased activity of CKK in blood serum during therapy or when the use of inhibitors of HMG-CoA reductase, including rosuvastatin, are stopped.It may be necessary to conduct additional studies of the muscular and nervous system, serological studies, as well as therapy with immunosuppressive means.
Signs of increased effects on skeletal muscle with rosuvastatin and concomitant therapy were not noted. However, there have been reports of an increase in the incidence of myositis and myopathy in patients taking other HMG-CoA reductase inhibitors in combination with fibrolic acid derivatives (eg gemfibrozil), cyclosporine, nicotinic acid in lipid-lowering doses (> 1 g / day), antifungal agents azole, HIV protease inhibitors and macrolide antibiotics.
When used simultaneously with certain HMG-CoA reductase inhibitors, gemfibrozil increases the risk of myopathy. Thus, simultaneous use of the drug Roxer® and gemfibrozil is not recommended. Advantages of further changes in plasma lipid concentration the combined use of the drug Roxer® with fibrates or nicotinic acid in lipid-lowering doses should be carefully weighed against the possible risks.The drug Roxer® at a dose of 30 mg / day is contraindicated for combination therapy with fibrates. Due to the increased risk of rhabdomyolysis, Roxer® should not be used in patients with acute conditions that can lead to myopathy or conditions predisposing to the development of renal failure (eg, sepsis, arterial hypotension, extensive surgical interventions, trauma, severe metabolic, endocrine and electrolyte disturbances or uncontrolled convulsions).
Liver
Depending on the daily dose, the drug Roxer® should be used with caution in patients with excessive alcohol use and / or having a history of liver disease or its use is contraindicated (see "Contraindications" and "C" caution ").
It is recommended to carry out the determination of functional liver samples before the start of therapy and 3 months after the beginning of therapy. Use of the drug Roxer® should stop or reduce the dose of the drug, if the activity of "liver" transaminases in serum is 3 times higher the upper limit of the norm.
In patients with hypercholesterolemia due to hypothyroidism or nephrotic syndrome before treatment with Roxer® should the main diseases.
Ethnic Features
During pharmacokinetic studies among representatives of the Mongoloid race compared with representatives European race plasma concentrations of rosuvastatin.
The drug Roxera® contains lactose, in with which it should not be applied patients with intolerance to lactose, deficiency of lactase, glucose- galactose malabsorption.
Interstitial lung disease
With the use of certain inhibitors HMG-CoA reductase, especially during long time, it was reported single cases of interstitial lung disease. Manifestations
diseases can be shortness of breath, unproductive cough and impairment general health (weakness, weight loss and fever). When suspected of interstitial lung disease should be discontinued therapy with HMG-CoA- reductase.
Diabetes mellitus type 2
In patients with glucose concentration from 5.6 to 6.9 mmol / L therapy rosuvastatin was associated with increased risk of developing diabetes mellitus type 2.
