Effect on kidney function
In patients who received high doses of rosuvastatin (mainly 40 mg), tubular proteinuria was observed in the urine test strip, which in most cases was transient. Such proteinuria did not indicate an acute kidney disease or progression of kidney disease. The frequency of reports on the development of serious adverse reactions from the kidneys in the postmarketing period was higher in patients taking rosuvastatin in a dose of 40 mg.
When using the drug Rosart at a dose of 40 mg, it is recommended to monitor the indices of kidney function during treatment.
Influence on the musculoskeletal system
With the use of all doses of rosuvastatin and, in particular, when doses exceeding 20 mg were reported, the development of myalgia, myopathy and, in rare cases, rhabdomyolysis. In very rare cases, the development of rhabdomyolysis with simultaneous administration of inhibitors of HMG-CoA reductase and ezetimibe has been reported.In this case, pharmacodynamic interaction can not be ruled out, so caution should be exercised when they are taken together. As with the administration of other inhibitors of HMG-CoA reductase, the frequency of postmarketing observation about the development of rhabdomyolysis associated with rosuvastatin was higher with a dose of 40 mg.
Determination of creatine phosphokinase
Determination of the activity of CKK should not be performed after intensive physical exertion or in the presence of other possible causes of an increase in its activity, which may lead to incorrect interpretation of the results. In case the initial activity of CK is significantly increased, after 5-7 days a repeated measurement should be performed - do not start therapy if the repeated test confirms the initial activity of CK (5 times higher than normal).
Before the start of therapy
Caution should be exercised when prescribing Rosart, as well as with the administration of other HMG-CoA reductase inhibitors, to patients with existing risk factors for myopathy / rhabdomyolysis (see section Carefully). It is necessary to consider the ratio of expected benefits from therapy and potential risk and to conduct clinical follow-up throughout the course of treatment.In the event that the initial activity of CK is significantly increased (5 times higher than ULN), then do not start treatment with the drug.
During treatment
The patient should be informed of the need to report immediately to the doctor about cases of sudden onset 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 the CK is significantly increased (more than 5 times compared with the IGN) or if the muscular symptoms are pronounced and cause daily discomfort (even if the CKK activity is 5 times less than the VLN). If symptoms disappear and CPK activity returns to normal, consideration should be given to re-administering Rosart or other HMG-CoA reductase inhibitors in smaller doses with careful monitoring of the patient. Routine monitoring 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 treatment or discontinuation of statins, including rosuvastatin, have been noted.There were no signs of an increase in the effect on skeletal musculature when taking rosuvastatin and concomitant therapy. 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 fibrin acid derivatives (including gemfibrozil), ciclosporin, nicotinic acid in lipid-lowering doses > 1 g / day, azole antifungal agents, protease inhibitors and macrolide antibiotics. Gemfibrozil increases the risk of myopathy with simultaneous administration with certain HMG-CoA reductase inhibitors, so the simultaneous use of gemfibrozil and rosuvastatin is not recommended. The ratio of expected benefit and potential risk should be carefully weighed in the combined use of Rosart and fibrates or nicotinic acid in lipid-lowering doses > 1 g / day. Contraindicated taking RosArt 40 mg at a time with fibrates (see sections Interaction with other medicines and contraindications). During treatment, especially during the dosage adjustment period of Rosart, every 2-4 weeks you should monitor the lipid profile and, if necessary, change the dose of the drug.Rosart should not be taken to patients with acute or severe myopathy or risk factors predisposing to the development of renal dysfunction and secondary rhabdomyolysis (eg, sepsis, arterial hypotension, extensive surgery, trauma, severe metabolic disorders, severe endocrine disorders, and severe violations of water-electrolyte balance, uncontrolled convulsions).
Effects on liver function
Like other inhibitors of HMG-CoA reductase rosuvastatin should be used with caution in patients who abuse alcohol and / or have a history of liver disease. It is recommended to carry out the determination of liver function indices before the start of therapy and 3 months after the start of therapy. Taking Roswart should stop or reduce the dose of the drug if the level of activity of "hepatic" transaminases in the serum is 3 times higher than VGN. In patients with hypercholesterolemia due to hypothyroidism or nephrotic syndrome, the treatment of underlying diseases should be performed prior to treatment with Rosart.In post-marketing surveillance of rosuvastatin, the frequency of reports on the development of serious violations of liver function (expressed primarily in an increase in the activity of "liver" transaminases) was higher with a dose of 40 mg.
Ethnic groups
In the course of pharmacokinetic studies, an increase in the systemic concentration of rosuvastatin was noted among patients of the Mongoloid race in comparison with the european race (see section Dosage and Administration and Pharmacokinetics).
HIV protease inhibitors
During the joint administration of rosuvastatin and a combination of different inhibitors of HIV proteases with ritonavir, an increase in the systemic concentration of rosuvastatin is observed. Careful evaluation should be made of a reduction in blood lipid concentrations, and also consider a possible increase in rosuvastatin in blood plasma at the beginning of treatment and during the period of increasing the dose of Rosart in patients with HIV taking HIV protease inhibitors. Simultaneous administration of HIV protease inhibitors is not recommended without dose adjustment for rosuvastatin (see section Dosing and Administration and Interaction with Other Drugs).
Interstitial lung disease
Some inhibitors of HMG-CoA reductase, especially for a long time, reported single cases of interstitial lung disease. Manifestations of the disease may be shortness of breath, unproductive cough and deterioration in overall health (weakness, weight loss and fever). If suspicion of interstitial lung disease should be discontinued therapy with HMG-CoA reductase inhibitors.
Diabetes mellitus type II
Some data confirm that HMG-CoA reductase inhibitors increase blood glucose concentration and increase the likelihood of developing type 2 diabetes in some patients. However, this risk is outweighed by the ability of HMG-CoA reductase inhibitors to reduce the risk of vascular complications, so this fact is not a reason to interrupt the treatment with rosuvastatin. It is necessary to establish a clinical observation and conduct a biochemical blood test according to national standards in patients at risk of developing hyperglycemia (blood glucose concentration 5.6-6.9 mmol / L, body mass index> 30 kg / m2, triglyceridemia, arterial hypertension).In one study of rosuvastatin, the overall incidence of diabetes mellitus was reported: 2.8% in the rosuvastatin group and 2.3% in the placebo group, mainly in patients with fasting glucose 5.6 - 6.9 mmol / l.
Lactose intolerance
The drug Rosart should not be taken to patients with lactose intolerance, lactase deficiency and glucose-galactose malabsorption, since it contains lactose monohydrate.
