Statinų šalutiniai poveikiai
Bendrieji šalutiniai poveikiai Galvos skausmas Nuovargis Virškinimo sutrikimai Panašūs į gripą simptomai Statin adverse events Statins are very safe. 95% of patients can tolerate them; 5% cannot. Common side effects include headache, upset stomach, fatigue, flu-like symptoms, and myalgia (without changes in creatine kinase [CK]). One or both liver transaminases may be elevated to >3 times the upper limit of normal on two consecutive occasions in 0.5% (with starting doses) to as high as 2.5% (with high doses) of patients in a dose-dependent manner. Whether statin-induced elevations in liver enzymes constitute true hepatotoxicity has not been determined. Cases of serious liver dysfunction or failure are exceedingly rare and not clearly related to statin therapy. Enzymes will frequently return to normal by reducing doses or even with continuation of therapy. If an elevation persists, discontinuation of therapy for a short period until levels return to normal is advised. Statin therapy may then be reinitiated. Myopathy defined as muscle symptoms (muscle weakness, aches, or soreness) plus CK >10 times the upper limit of normal is seen in 2–4 patients per In 77,000 patient-years of use in the landmark clinical trials, 8 cases of myopathy were reported. Very rare cases of rhabdomyolysis, myoglobinuria, acute renal necrosis, and death have been reported. The incidence of myopathy appears related to the systemic blood concentration of the statin. Myopathy is most likely to occur with higher doses, in patients with renal impairment, when a statin is combined with a fibrate, when a drug interfering with the metabolism of the statin is given concurrently (e.g., macrolide antibiotics, certain antifungal medications, gemfibrozil, cyclosporine), and in elderly women. All patients started on statins should be instructed to report immediately muscle symptoms or brown urine and to have CK measured. If myopathy is present or strongly suspected, the statin should be discontinued immediately.

Statinų sukeliami pašaliniai reiškiniai
Miopatijos Transaminazių koncentracijos padidėjimas Proteinurija Vaistų sąveika Five main safety considerations arise with the use of statins: associated adverse events (eg, headache, nausea, myalgia); elevated transaminase levels; muscle toxicity; renal function; and drug interactions. Each of these topics will be covered in detail in this slide presentation. One or both liver transaminases may be elevated to >3 times the upper limit of normal on two consecutive occasions in 0.5% (with starting doses) to as high as 2.5% (with high doses) of patients in a dose-dependent manner. Whether statin-induced elevations in liver enzymes constitute true hepatotoxicity has not been determined. Cases of serious liver dysfunction or failure are exceedingly rare and not clearly related to statin therapy. Enzymes will frequently return to normal by reducing doses or even with continuation of therapy. If an elevation persists, discontinuation of therapy for a short period until levels return to normal is advised. Statin therapy may then be reinitiated.

These trials included over 30,000 participants. Forty patients in the placebo groups and 50 in the statin groups experienced asymptomatic elevations of CK (>10 ULN). This represents an odds ratio of 1.25, although this difference was not statistically significant. There were 258 patients with elevated ALT/aspartate aminotransferase (AST) (>3 ULN) in the placebo groups compared with 290 in the statin groups. This corresponded to an odds ratio of 1.13 and again without any statistical significance. LaRosa JC, He H, Vupputuri S. Effect of statins on risk of coronary disease.

As a result, there is a general perception that the risk of myopathy and rhabdomyolysis with all statins is dose-related. The 2006 safety meta-analysis, which included over 4500 patients receiving the 80-mg dose, did not show any evidence of a dose-dependent increase in myopathy and rhabdomyolysis with atorvastatin. No cases of rhabdomyolysis were observed across the 49 trials included in this analysis.1 Trials studying high-dose atorvastatin that were not included in the 2006 safety meta-analysis include PROVE IT, IDEAL, and TNT. The incidences of persistent CPK elevations >10 x ULN and myopathy with the 80 mg dose of atorvastatin were low and similar across the trials. No cases of rhabdomyolysis were reported in the PROVE-IT trial.2 Two cases of investigator-reported rhabdomyolysis were reported with atorvastatin 80 mg in the IDEAL trial and 5 cases of rhabdomyolysis were reported in the TNT trial (2 in the atorvastatin 80-mg group and 3 in the atorvastatin 10-mg group). All of the patients had at least one predisposing risk factor for myopathy and rhabdomyolysis and none was considered by the on-site investigator to be causally related to atorvastatin.3,4 NR, not reported *Studies not included in 2006 safety meta-analysis †Investigator-reported cases: did not meet criteria for definition of myopathy (persistent CPK elevations >10 x ULN with muscle symptoms) 1.

Gydymo taktika, nustačius KK koncentracijos padidėjimą be miopatijos simptomų
KK padidėjusius iki 5X, gydymą statinu galima tęsti, stebint KK koncentraciją KK padidėjusius >5X, gydymą statinu nutraukti. KK sumažėjus pradėti gydymą kitu statinu arba mažesne naudoto statino doze On initiating statin therapy, it is essential to obtain a baseline CK level and essential to monitor the level if a patient reports muscle symptoms. Minor CK elevations are not necessarily diagnostic in clinical practice because they are frequently seen in statin users as well as nonusers. Patients at high risk for a vascular event who report minor myalgias should be encouraged to continue treatment. If serious myalgias or muscle weakness develops, however, statin treatment must be discontinued. Statins should also be discontinued if CK rises to >10 ULN and myalgias are reported, an indication of myositis. If patients who begin to develop muscle discomfort and/or weakness also begin to show progressive CK elevations, a reduction in dosage or temporary discontinuation of statin therapy is recommended. Then a decision whether or when to reinstitute statin therapy can be made. Although it is rarely seen in patients on statin monotherapy, patients with complex medical problems and/or who are on polytherapy are more likely to present with myositis. Pasternak RC, et al.

Common side effects include headache, upset stomach, fatigue, flu-like symptoms, and myalgia (without changes in creatine kinase [CK]). One or both liver transaminases may be elevated to >3 times the upper limit of normal on two consecutive occasions in 0.5% (with starting doses) to as high as 2.5% (with high doses) of patients in a dose-dependent manner. Whether statin-induced elevations in liver enzymes constitute true hepatotoxicity has not been determined. Cases of serious liver dysfunction or failure are exceedingly rare and not clearly related to statin therapy. Enzymes will frequently return to normal by reducing doses or even with continuation of therapy. If an elevation persists, discontinuation of therapy for a short period until levels return to normal is advised. Statin therapy may then be reinitiated. Myopathy defined as muscle symptoms (muscle weakness, aches, or soreness) plus CK >10 times the upper limit of normal is seen in 2–4 patients per In 77,000 patient-years of use in the landmark clinical trials, 8 cases of myopathy were reported. Very rare cases of rhabdomyolysis, myoglobinuria, acute renal necrosis, and death have been reported. The incidence of myopathy appears related to the systemic blood concentration of the statin. Myopathy is most likely to occur with higher doses, in patients with renal impairment, when a statin is combined with a fibrate, when a drug interfering with the metabolism of the statin is given concurrently (e.g., macrolide antibiotics, certain antifungal medications, gemfibrozil, cyclosporine), and in elderly women. All patients started on statins should be instructed to report immediately muscle symptoms or brown urine and to have CK measured. If myopathy is present or strongly suspected, the statin should be discontinued immediately.

Statinai ir CYP 450 fermentų sistema
Statinas Kepenų CYP450 fermentai Statino arba jo aktyvaus metabolito Koncentracija kraujyje Miopatijos rizika 3A4 Following administration, the primary enzyme system responsible for the metabolism of statins is the CYP450 system, which includes more than 100 different CYP genes. The 2 isozymes predominantly responsible for the metabolism of statins are CYP3A4 and CYP2C9. Inhibitors of these enzymes can produce a decrease in the metabolism of statins, resulting in increased and prolonged blood concentrations of the statin or its active metabolites. This has the potential to increase the risk for muscle toxicity. Williams D, Feely J. Pharmacokinetic-pharmacodynamic drug interactions with HMG-CoA reductase inhibitors.

The CYP3A family of enzymes is responsible for the metabolism of atorvastatin, lovastatin, and simvastatin. Fluvastatin is primarily metabolized by CYP2C9, as is rosuvastatin to a minor extent. Pravastatin, on the other hand, is not significantly metabolized by the CYP system; it is primarily eliminated unchanged by phase II reactions. Williams D, Feely J.

Due to the wave of new trials examining the use of high-dose statins, patient exposure to the 80-mg dose in clinical trials has increased substantially over the past few years. The second meta-analysis that was completed in 2004 represents over 4500 patient-years of exposure to the 80-mg dose of atorvastatin in clinical trials and provides a substantial amount of evidence on the safety and tolerability of this dose.2 >121 million patient-years of exposure to atorvastatin in the real world Adapted from Newman CB, et al.

This same signal does not appear consistent across the dose ranges of other statins.1 It is also worth noting that there may be predisposing patient conditions or concomitant medications that may cause increased plasma concentrations of a drug. As such, a dose-dependent trend on rates of proteinuria may necessitate greater vigilance (even when administering lower doses). 1. AstraZeneca FDA Advisory Committee Presentation.

Statinų sukelta proteinurija
Proteinuriją gali sukelti bet kuris statinas, sutrikdydamas baltymo reabsorbciją Proteinurija nuo dozės priklausoma statinų klasės savybė Su šlapimu išsiskiriantys proteinai yra mažos molekulinės masės Statinų sukelta proteinurija nelemia inkstų funkcijos pablogėjimo Statinai gerina inkstų kraujotaką ir didna glomerulų filtraciją This topic will be expanded upon in the next slides.Rozuvastatino 80 mg doze sukele inkst7 nepakankamuma taciau derinyje su antibiotikais taciau 5-40 mg netgi sumazino kreatnino koncentracija

Dažniausi klausimai Ar saugu skirti statinus, esant mažai cholesterolio koncentracijai? Ką daryti, jeigu atsiranda pašaliniai reiškiniai? Kada nutraukti statinų skyrimą? Ar didelės statinų dozės saugios? Kokia yra sąveika su kitais medikamentais?

Statinų sąveika su kitais medikamentais
Vaistas Atorv Fluv Lov Prav Rosuv Simv Cyklosporinas + – Digoxinas Eritromcinas Warfarinas Cyclosporine has been shown to increase plasma concentrations of atorvastatin, lovastatin, pravastatin, simvastatin, and rosuvastatin. More importantly, an increased incidence of myopathy and rhabdomyolysis has been reported in transplant patients taking these agents concomitantly. Macrolide antibiotics, such as erythromycin, are potent inhibitors of CYP3A4 and, therefore, have the potential to interact with statins metabolized by this pathway. Since fluvastatin, pravastatin, and rosuvastatin are metabolized by other routes, these agents are less likely to be influenced by this interaction. Coadministration of simvastatin and digoxin has been reported to increase digoxin concentrations by 20%. Similarly, coadministration of atorvastatin increased digoxin levels by 15%. This means that digoxin concentrations should be monitored more frequently when these combinations are used. Some statins (lovastatin, fluvastatin, simvastatin, and rosuvastatin) have been reported to interact with warfarin, with a few case reports of increased anticoagulant effects and bleeding. The coadministration of warfarin with any statin affects the international normalized ratio (INR). Increased and decreased prothrombin time responses have been reported in patients who are concurrently taking warfarin and statins. As with most medications, anticoagulant control should be carefully monitored when patients who receive oral anticoagulants begin taking statins. Paoletti R, Corsini A, Bellosta S.

Kaip padidinti statinų ir fibratų derinio saugumą?
Gydyti vien tik statinais Statino ir omega-3 riebiųjų rūgšių ar niacino derinys saugesnis, nei statinų ir fibratų derinys Statinus ir fibratus derinyje skirti mažesnėmis dozėmis Statiną ir fibratą skirti skirtingu paros laiku Steps to minimize the risk of muscle toxicity with fibrate–statin combination therapy The greatest issue with the use of a fibrate and statin in combination is the increased risk of causing myopathy and rhabdomyolysis. This risk is enhanced with high statin doses, in the presence of renal insufficiency, in older patients, and whenever drugs that may interfere with statin metabolism are given concurrently. To minimize the muscle side effects when combining any of these drugs with a statin, the following suggestions are made. Try to achieve LDL-C and non-HDL-C treatment goals with a statin alone. If adding a triglyceride-lowering drug to the statin, give preference to fish oils or niacin, as the risk of myopathy appears low. If a fibrate is to be added, fenofibrate is preferred over gemfibrozil, since there may be a lower risk of myopathy. Use the lowest effective dose of both the statin and fibrate to achieve treatment goals (e.g., starting dose of a statin with 63–126 mg of fenofibrate). Dose the fibrate in the morning and the statin in the evening (note that this suggestion is based on theoretical considerations and not on any evidence that this recommendation will reduce the incidence of muscle toxicity). Avoid (or cautiously use) statins in patients who have compromised renal function (as is often found in elderly patients) or hepatic function (including alcoholics). Assure that no other drugs are or will be used concurrently that could interfere with the metabolism of the statin. Obtain a baseline CK level and repeat it during the course of therapy if the patient reports muscle symptoms. Teach the patient to recognize and report muscle weakness, tenderness, or pain and be prepared to evaluate patients who experience these symptoms. Discontinue therapy if muscle symptoms are present and a CK is >10 times the upper limit of normal.
