Statins in cardiometabolic disease: what makes pitavastatin different?

The term cardiometabolic disease encompasses a range of lifestyle-related conditions, including Metabolic syndrome (MetS) and type 2 diabetes (T2D), that are characterized by different combinations of cardiovascular (CV) risk factors, including dyslipidemia, abdominal obesity, hypertension, hyperglycemia/insulin resistance, and vascular inflammation. These risk factors individually and interdependently increase the risk of CV and cerebrovascular events, and represent one of the biggest health challenges worldwide today. CV diseases account for almost 50% of all deaths in Europe and around 30% of all deaths worldwide. Furthermore, the risk of CV death is increased twofold to fourfold in people with T2D. Whilst the clinical management of CV disease has improved in Western Europe, the pandemic of obesity and T2D reduces the impact of these gains. This, together with the growing, aging population, means the number of CV deaths is predicted to increase from 17.1 million worldwide in 2004 to 23.6 million in 2030. The recommended treatment for MetS is lifestyle change followed by treatment for the individual risk factors. Numerous studies have shown that lowering low-density lipoprotein-cholesterol (LDL-C) levels using statins can significantly reduce CV risk in people with and without T2D or MetS. However, the risk of major vascular events in those attaining the maximum levels of LDL-C-reduction is only reduced by around one-third, which leaves substantial residual risk. Recent studies suggest that low high-density lipoprotein-cholesterol (HDL-C) (<1 .0 mmol/l; 40 mg/dl) and high triglyceride levels (≥1.7 mmol/l; 150 mg/dl) are independent risk factors for CV disease and that the relationship between HDL-C and CV risk persists even when on-treatment LDL-C levels are low (<1.7 mmol/l; 70 mg/dl). European guidelines highlight the importance of reducing residual risk by targeting these risk factors in addition to LDL-C. This is particularly important in patients with T2D and MetS because obesity and high levels of glycated hemoglobin are directly related to low levels of HDL-C and high triglyceride. Although most statins have a similar low-density lipoprotein-lowering efficacy, differences in chemical structure and pharmacokinetic profile can lead to variations in pleiotropic effects (for example, high-density lipoprotein-elevating efficacy), adverse event profiles, and drug-drug interactions. The choice of statin should therefore depend on the needs of the individual patient. The following reviews will discuss the potential benefits of pitavastatin versus other statins in the treatment of patients with dyslipidemia and MetS or T2D, focusing on its effects on HDL-C quantity and quality, its potential impact on atherosclerosis and CV risk, and its metabolic characteristics that reduce the risk of drug interactions. Recent controversies surrounding the potentially diabetogenic effects of statins will also be discussed.     

Pitavastatin in cardiometabolic disease: therapeutic profile

Statins effectively lower low-density lipoprotein-cholesterol (LDL-C) and reduce cardiovascular risk in people with dyslipidemia and cardiometabolic diseases such as Metabolic syndrome (MetS) or type 2 diabetes (T2D). In addition to elevated levels of LDL-C, people with these conditions often have other lipid-related risk factors, such as high levels of triglycerides, low levels of high-density lipoprotein-cholesterol (HDL-C), and a preponderance of highly atherogenic, small, dense low-density lipoprotein particles. The optimal management of dyslipidemia in people with MetS or T2D should therefore address each of these risk factors in addition to LDL-C. Although statins typically have similar effects on LDL-C levels, differences in chemical structure and pharmacokinetic profile can lead to variations in pleiotropic effects, adverse event profiles and drug-drug interactions. The choice of statin should therefore depend on the characteristics and needs of the individual patient. Compared with other statins, pitavastatin has distinct pharmacological features that translate into a broad range of actions on both apolipoprotein-B-containing and apolipoprotein-A-containing lipoproteins. Studies show that pitavastatin 1 to 4 mg is well tolerated and significantly improves LDL-C and triglyceride levels to a similar or greater degree than comparable doses of atorvastatin, simvastatin or pravastatin, irrespective of diabetic status. Moreover, whereas most statins show inconsistent effects on HDL-C levels, pitavastatin-treated patients routinely experience clinically significant elevations in HDL-C that are maintained and even increased over the long term. In addition to increasing high-density lipoprotein quantity, pitavastatin appears to improve high-density lipoprotein function and to slow the progression of atherosclerotic plaques by modifying high-density lipoprotein-related inflammation and oxidation, both of which are common in patients with MetS and T2D. When choosing a statin, it is important to note that patients with MetS have an increased risk of developing T2D and that some statins can exacerbate this risk via adverse effects on glucose regulation. Unlike many statins, pitavastatin appears to have a neutral and even beneficial effect on glucose regulation, making it a useful treatment option in this high-risk group of patients. Together with pitavastatin’s beneficial effects on the cardiometabolic lipid profile and its low potential for drug-drug interactions, this suggests that pitavastatin might be a useful lipid-lowering option for people with cardiometabolic disease.     

Statins: are any questions unanswered?

PURPOSE OF REVIEW: To summarize recent and ongoing randomized trials of statin therapy for the prevention of major vascular events. RECENT FINDINGS: Four large-scale randomized trials have compared high-dose vs. standard doses of statin therapy among patients with coronary heart disease, and their results suggest that higher doses are more effective for preventing major vascular events, albeit with evidence of increased toxicity. There is now clear evidence that statin therapy is effective among most patients with type 2 diabetes, although uncertainty remains about the benefits in those with advanced nephropathy. Ongoing trials will assess whether statin therapy is beneficial among patients with noncoronary vascular disease (such as congestive heart failure, cerebrovascular disease, or aortic stenosis), and among people with comorbid conditions or risk factors that increase the risk of vascular disease (including chronic kidney disease and raised C-reactive protein with below average low-density lipoprotein cholesterol). SUMMARY: Statin therapy safely reduces the risk of vascular events in a wide range of patients. Uncertainties persist about the effects of higher statin doses and the role of statins among patients with specific conditions or risk factors.     

Cholesterol metabolism,pancreatic β-cell function and diabetes

Cholesterol plays an essential role in determining cell membrane physico-chemical characteristics and functions. A proper membrane structure is critical in pancreatic β-cells for glucose-mediated insulin secretion, and alterations in cellular cholesterol content may negatively affect this process, leading to β-cell dysfunction. The low density lipoprotein receptor (LDL-R) appears to play a relevant role in ß-cell dysfunction due to cholesterol accumulation. This observation raised the question of whether hypocholesterolemic drugs which increase LDL-R expression might bear diabetogenic properties, thus increasing the risk of new-onset diabetes or worsen glycaemic parameters in diabetic patients.Being at higher cardiovascular risk, diabetic patients are usually treated with hypolipidemic drugs to correct the atherogenic dyslipidemia characteristic of this pathological condition. Statin therapy has been associated with an increased incidence of new-onset diabetes (NOD), being the diabetogenic effect depending on the type and dose of statin. However, it is worth noting that the benefits on cardiovascular mortality largely exceed the increased risk associated with the development of diabetes. Although genetic variants associated with lower levels of LDL-C are also associated with an increased NOD risk, clinical trials with lipid-lowering drugs other than statins, namely ezetimibe or monoclonal antibodies against PCSK9, did not observe an increase of developing diabetes.In summary, molecular evidence clearly points to a key role for cholesterol homeostasis in pancreatic β-cell function which, in humans, is negatively affected by statins. Available data exclude that this could be the case for other hypocholesterolemic approaches, but long-term studies are warranted to explore this critical aspect.     

Statin-induced myositis: a commonly encountered or rare side effect?

PURPOSE OF REVIEW: Statins are well established as first-line agents for cholesterol lowering in cardiovascular disease, with accumulating evidence supporting their initiation and guidelines recommending treatment to lower LDL levels. Although generally well tolerated with few side effects, including headaches and gastrointestinal symptoms, concerns are raised regarding myopathy, which may lead to fatal rhabdomyolysis. This review examines current evidence on statin interactions, mechanism of injury and toxicity. RECENT FINDINGS: Significant myopathy is rare with an incidence of less than 0.5% of patients. Statin side effects may be dose-related, associated with other drug interactions that interfere with statin metabolic pathways through cytochrome p450 pathways or glucuronidation, or related to co-morbidities. Several theories have suggested that statin myotoxicity may be due to intracellular cholesterol depletion, or interference with oxidative phosphorylation pathways. Exact mechanisms are yet to be fully defined. Individuals with mixed dyslipidaemia may require combination therapy to achieve target lipid levels. No large-scale randomized trials have yet reported on the safety of combination therapy, although more recent studies may shed some light when they report. CONCLUSION: As most individuals on statins are 'high-risk' patients, they tend to be on multiple agents for cardiovascular disease which may interact with their statin. Progression of myalgia or myositis to rhabdomyolysis is rare (one in 30-100,000 patient-years of exposure), but if progressive muscle symptoms are ignored then fatalities can occur. When prescribing statins, physicians should be alert to potential risks and educate patients to report any potentially significant symptoms.     

Statin Intolerance: A Review and Update

ObjectiveTo review the evidence of existing literature on the management of statin intolerance.MethodsWe searched for literature pertaining to statin intolerance and treatments in PubMed. We reviewed articles published between 2005 and 2022.ResultsStatin-associated myalgia is the most common adverse effect of statin therapy and the most common reason for statin discontinuation. The risk factors for statin intolerance include unexplained muscle pain with other lipid-lowering therapy, unexplained cramps, a history of increased creatine kinase levels, a family history of muscle symptoms, and a family history of muscle symptoms with lipid therapy. Vitamin D repletion and coenzyme Q supplementation may help alleviate the musculoskeletal effects of statins. Trials of different types of statins and different dosing regimens are recommended to improve tolerability. The use of statins in individuals who perform regular exercise requires closer attention to muscular symptoms and creatine kinase levels; however, it does not preclude the use of statins.ConclusionManagement of the adverse effects of statin therapy and improving statin tolerability are key to achieving optimum cardiovascular benefits. Identifying statin-associated adverse effects and managing them appropriately can reduce unnecessary statin discontinuation and subsequently provide longer cardiovascular protection.     

Anti-atherogenic effects of fibrates in type 2 diabetes

Type 2 diabetes is an increasing cause of premature coronary heart disease. Several trials with lipid-modifying therapy have included sufficient numbers of diabetics to indicate that treatment of diabetic dyslipidaemia with either fibrates or statins reduces the risk of future coronary events in such patients. However, until recently no reported study had been designed specifically to investigate the effects of intervening in patients with type 2 diabetes. The Diabetes Atherosclerosis Intervention Study (DAIS) is an angiographic study in which 418 diabetic subjects were randomized to micronised fenofibrate or placebo groups. After 3 years of treatment, the fenofibrate group had a significantly reduced rate of progression of coronary atherosclerosis. This study, when considered with the results of other studies that have included diabetics, has important implications for the treatment of diabetic dyslipidaemia. The evidence that is currently available supports a place for both fibrates and statins, either as monotherapy or in combination, in the treatment of diabetic dyslipidaemia.     

Statins restore ischemic limb blood flow in diabetic microangiopathy via eNOS/NO upregulation but not via PDGF-BB expression

3-Hydroxy-3-methyl-glutaryl CoA reductase inhibitors, or statins, have pleiotropic effects and can protect the vasculature in a manner independent of their lipid-lowering effect. The effectiveness of statins in reducing the risk of coronary events has been shown even in patients with diabetes, and their effects on diabetic complications have been reported. Using a model of severe hindlimb ischemia in streptozotocin-induced diabetic mice (STZ-DM), we investigated the effects and mechanisms of statin therapy in diabetic angiopathy in ischemic hindlimbs. As a result, STZ-DM mice frequently lost their hindlimbs after induced ischemia, whereas non-DM mice did not. Supplementation with statins significantly prevented autoamputation. We previously showed that diabetic vascular complications are caused by impaired expression of PDGF-BB, but statin therapy did not enhance PDGF-BB expression. Statins helped enhance endogenous endothelial nitric oxide (NO) synthase (eNOS) expression. Furthermore, the inhibition of NO synthesis by the administration of N(omega)-nitro-l-arginine methyl ester impaired the ability of statins to prevent STZ-DM mouse limb autoamputation, indicating that the therapeutic effect of statins in hindlimb ischemia in STZ-DM mice occurs via the eNOS/NO pathway. A combination therapy of statins and PDGF-BB gene supplementation was more effective for diabetic angiopathy than either therapy alone. In conclusion, these findings indicate that statin therapy might be useful for preventing intractable diabetic foot disease in patients with diabetic angiopathy.     

Cardiovascular outcomes among participants with diabetes in the recent large statin trials

PURPOSE OF REVIEW: Despite their increased cardiovascular risk and its continuous relationship with cholesterol, until recently only diabetic patients with marked dyslipidaemia were routinely offered lipid-lowering therapy. The secondary prevention statin trials led to more widespread cholesterol lowering in patients with coronary disease and diabetes. Here we review the results of recent randomized trials, which included substantial numbers of patients with diabetes and no vascular disease. RECENT FINDINGS: The MRC/BHF Heart Protection Study included 5963 participants with diabetes, of whom 2912 had no history of vascular disease at baseline. Patients were randomized to 40 mg simvastatin daily or matching placebo for 5 years, which, on average, reduced LDL by 1.0 mmol/l compared with placebo. Highly significant reductions of about one-quarter in major vascular events were seen both overall and in different types of patient with diabetes, including those with average and below average lipid levels. Recent data from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial and the Anglo-Scandinavian Cardiac Outcomes Trial support these findings and are consistent with these effects. SUMMARY: Good quality, randomized trials including substantial numbers of patients with diabetes show that such patients obtain the same proportional benefit as other groups studied. Given their increased cardiovascular risk, these findings argue for a simple strategy of considering routine statin therapy for patients with type 2 diabetes and adult patients with type 1 diabetes, irrespective of lipid levels. As generic statins become available this could have a greater impact on the burden of cardiovascular disease in diabetes than restricted and targeted therapy.     

Effect of Statins on Venous Thromboembolic Events: A Meta-analysis of Published and Unpublished Evidence from Randomised Controlled Trials

Background

It has been suggested that statins substantially reduce the risk of venous thromboembolic events. We sought to test this hypothesis by performing a meta-analysis of both published and unpublished results from randomised trials of statins.

Methods and Findings

We searched MEDLINE, EMBASE, and Cochrane CENTRAL up to March 2012 for randomised controlled trials comparing statin with no statin, or comparing high dose versus standard dose statin, with 100 or more randomised participants and at least 6 months'' follow-up. Investigators were contacted for unpublished information about venous thromboembolic events during follow-up. Twenty-two trials of statin versus control (105,759 participants) and seven trials of an intensive versus a standard dose statin regimen (40,594 participants) were included. In trials of statin versus control, allocation to statin therapy did not significantly reduce the risk of venous thromboembolic events (465 [0.9%] statin versus 521 [1.0%] control, odds ratio [OR] = 0.89, 95% CI 0.78–1.01, p = 0.08) with no evidence of heterogeneity between effects on deep vein thrombosis (266 versus 311, OR 0.85, 95% CI 0.72–1.01) and effects on pulmonary embolism (205 versus 222, OR 0.92, 95% CI 0.76–1.12). Exclusion of the trial result that provided the motivation for our meta-analysis (JUPITER) had little impact on the findings for venous thromboembolic events (431 [0.9%] versus 461 [1.0%], OR = 0.93 [95% CI 0.82–1.07], p = 0.32 among the other 21 trials). There was no evidence that higher dose statin therapy reduced the risk of venous thromboembolic events compared with standard dose statin therapy (198 [1.0%] versus 202 [1.0%], OR = 0.98, 95% CI 0.80–1.20, p = 0.87). Risk of bias overall was small but a certain degree of effect underestimation due to random error cannot be ruled out. Please see later in the article for the Editors'' Summary.

Conclusions

The findings from this meta-analysis do not support the previous suggestion of a large protective effect of statins (or higher dose statins) on venous thromboembolic events. However, a more moderate reduction in risk up to about one-fifth cannot be ruled out.     

Regulation of osteoclast differentiation by statins

HMG-CoA reductase inhibitor (statin) treatment is frontline therapy for lowering plasma cholesterol levels in patients with hyperlipidemia. In a few case studies, analysis of clinical data has revealed a decreased risk of fracture in patients on statin therapy. However, this reduction in the incidence of fracture is not always observed nor is it supported by an increase in bone density, which further complicates our understanding of the role of statins in bone metabolism. Thus, the precise role of statins in bone metabolism remains poorly understood. In this study, we examined the effect of statin treatment on osteoclastogenesis. Treatment with lovastatin resulted in a significant, dose-dependent decrease in the numbers of differentiated osteoclasts and decreased cholesterol biosynthesis activity with an EC(50) similar to that observed in freshly isolated rat or cultured human liver cells. Studies assessing the role of mevalonate metabolites in the development of the osteoclasts demonstrated that geranylgeraniol, but not squalene or farnesol was important for the development and differentiation of osteoclasts, implicating protein geranylgeranylation rather than protein farnesylation as a key factor in the osteoclast differentiation process. In conclusion, our data indicate that lovastatin inhibits osteoclast development through inhibition of geranylgeranylation of key prenylated proteins and that the bone effects of statins are at least partially due to their effects on osteoclast numbers.     

Clinical implications for statin pleiotropy

PURPOSE OF REVIEW: Atherosclerosis is a multi-factorial condition involving dyslipidemia that can result in cardiovascular disease. Statins are potent inhibitors of cholesterol biosynthesis, and in clinical trials, statins have been shown to be beneficial in the primary and secondary prevention of coronary heart disease. However, the overall benefits observed with statins appear to occur much earlier and to be greater than what might be expected from changes in lipid levels alone, suggesting effects beyond cholesterol lowering. SUMMARY OF FINDINGS: Recent studies indicate that some of the cholesterol-independent or 'pleiotropic' effects of statins involve improving endothelial function, enhancing the stability of atherosclerotic plaques, decreasing oxidative stress and inflammation, and inhibiting the thrombogenic response. Many of these pleiotropic effects are mediated by inhibition of isoprenoids, which serve as lipid attachments for intracellular signaling molecules. In particular, inhibition of small GTP-binding proteins, Rho, Ras, and Rac, whose proper membrane localization and function are dependent upon isoprenylation, may play an important role in mediating the pleiotropic effects of statins. SUMMARY: The potential clinical implications of statin pleiotropy suggests that perhaps other biomarkers, in addition to lipid levels, should be used to gauge the full efficacy of statin therapy in patients with cardiovascular risks or that statin therapy may be effective in disease states, such as inflammatory conditions, ischemic stroke or cancer, where elevated cholesterol levels have not been shown to be a strong epidemiological risk for these diseases.     

Statins – Do we really know all mechanisms of action of this group of drugs?

The role of statins in the treatment and prevention of cardiovascular diseases, such as coronary artery disease, acute coronary syndromes, diabetes or stroke is well established. However, there are still many questions regarding the role of statins in patients with heart failure (HF)/cardiomyopathy (CM), hypertension, atrial fibrillation (AF) and chronic kidney disease (CKD). As for patients with HF/CM inhibition of inflammation, reducing endothelial dysfunction might comprise part of the underlying mechanisms leading to the improvement of left ventricular function and exercise tolerance in these groups of patients. Therefore the candidates for statin therapy with HF/CM should be in New York Heart Association class II or III and should have normal or increased levels of lipids. We should avoid reducing lipids levels in these patients. At present, it is also difficult to unequivocally assess the impact of statins on blood pressure (BP). However, according to most available studies, the impact of statins on the decrease in BP is slight, but significant, especially among patients with hypertension. Moreover statins significantly reduce cardiovascular events in patients with hypertension. Although the results of trials concerning the use of statins in CKD patients are conflicting, it is suggested that the benefits of statin use outweigh the drawbacks in patients with early-stage CKD, when the benefits can be effectively predicted. However, available large randomized clinical trials suggest a lack of efficacy in patients on renal replacement therapy. We also needs further data on the role of statins on AF, however the existing studies suggest beneficial impact of statins in these patients.     

Intensive statin therapy in acute coronary syndromes: clinical benefits and vascular biology

PURPOSE OF REVIEW: The results of a landmark clinical study comparing intensive statin therapy with conventional statin therapy, in patients with acute coronary syndromes (ACS), are reviewed. The mechanisms behind these results are analysed drawing data from vascular and cell biology. RECENT FINDINGS: The Pravastatin or Atorvastatin Evaluation and Infection Therapy-Thrombolysis in Myocardial Infarction (PROVE IT-TIMI 22) study showed that intensive statin therapy with 80 mg of atorvastatin to achieve a low-density lipoprotein cholesterol of 62 mg/dl resulted in a 3.9% absolute and a 16% relative risk reduction in death or major cardiovascular events up to 2 years, compared to 40 mg of pravastatin, in patients with ACS. The results were especially significant as intensive statin therapy resulted in a very early benefit (<30 days) and occurred against a background of percutaneous coronary intervention (69%) for the index admission and high use of medications for secondary prevention. The PROVE IT and the Myocardial Ischaemia Reduction with Aggressive Cholesterol Lowering (MIRACL) C-reactive protein sub-study also showed that atorvastatin (80 mg) resulted in a significant reduction in markers of inflammation, whilst the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) study showed that intensive statin therapy was associated with reduced progression of atherosclerosis compared with conventional doses of statins. SUMMARY: Intensive statin therapy results in a significant early reduction in adverse cardiac events in ACS patients which are sustained over 2 years. The early benefits seen are likely to result from modulation of inflammation, endothelial function and coagulation, i.e. the pleiotropic effects, whereas the greater reduction in low-density lipoprotein cholesterol results in reduced long-term events.     

The safety and efficacy of achieving very low LDL-cholesterol concentrations with high dose statin therapy

PURPOSE OF REVIEW: The benefits of lipid lowering with statins are established in patients with or at risk for coronary artery disease. Recent trials with high doses of potent statins have examined treating to very low levels of LDL-cholesterol. Concerns have been raised about the safety of this strategy. This review examines the safety and efficacy of treating to very low LDL-cholesterol. RECENT FINDINGS: Four clinical trials, Treating to New Targets (TNT) and Incremental Decrease in End Points Through Aggressive Lipid Lowering (IDEAL) in stable coronary artery disease and Aggrastat to Zocor (A to Z) and Pravastatin or Atorvastatin Evaluation and Infection Therapy (PROVE IT)-TIMI 22 following acute coronary syndromes, have examined intensive statin therapy compared to moderate statin therapy. These trials and a meta-analysis demonstrated that intensive statin therapy reduces cardiovascular events. Subsequent analyses from these trials suggest that very low levels of LDL-cholesterol can be achieved safely and may improve clinical outcomes. A note of caution regarding hemorrhagic events following stroke with intensive statin therapy was raised by the Stroke Prevention by Aggressive Reduction of Cholesterol Levels (SPARCL) trial despite impressive reductions in cardiovascular events. SUMMARY: A growing body of evidence suggests progressive benefit for lowering LDL-cholesterol aggressively with intensive statin therapy in coronary artery disease. Future trials will be needed to define whether there is a level of LDL-cholesterol beyond which further benefit is not seen or safety concerns emerge.     

Persistence with Statins and Onset of Rheumatoid Arthritis: A Population-Based Cohort Study

Background

The beneficial effects of statins in rheumatoid arthritis (RA) have been suggested previously, but it is unclear whether statins may prevent its development. The aim of this retrospective cohort study was to explore whether persistent use of statins is associated with onset of RA.

Methods and Findings

The computerized medical databases of a large health organization in Israel were used to identify diagnosed RA cases among adults who began statin therapy between 1998 and 2007. Persistence with statins was assessed by calculating the mean proportion of follow-up days covered (PDC) with statins for every study participant. To assess the possible effects of healthy user bias, we also examined the risk of osteoarthritis (OA), a common degenerative joint disease that is unlikely to be affected by use of statins.A total of 211,627 and 193,770 individuals were eligible for the RA and OA cohort analyses, respectively. During the study follow-up period, there were 2,578 incident RA cases (3.07 per 1,000 person-years) and 17,878 incident OA cases (24.34 per 1,000 person-years). The crude incidence density rate of RA among nonpersistent patients (PDC level of <20%) was 51% higher (3.89 per 1,000 person-years) compared to highly persistent patients who were covered with statins for at least 80% of the follow-up period. After adjustment for potential confounders, highly persistent patients had a hazard ratio of 0.58 (95% confidence interval 0.52–0.65) for RA compared with nonpersistent patients. Larger differences were observed in younger patients and in patients initiating treatment with high efficacy statins. In the OA cohort analysis, high persistence with statins was associated only with a modest decrement in risk ratio (hazard ratio = 0.85; 0.81–0.88) compared to nonadherent patients.

Conclusions

The present study demonstrates an association between persistence with statin therapy and reduced risk of developing RA. The relationship between continuation of statin use and OA onset was weak and limited to patients with short-term follow-up. Please see later in the article for the Editors'' Summary     

A comprehensive review on the lipid and pleiotropic effects of pitavastatin

The 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, or statins, are administered as first line therapy for hypercholesterolemia, both in primary and secondary prevention. There is a growing body of evidence showing that beyond their lipid-lowering effect, statins have a number of additional beneficial properties. Pitavastatin is a unique lipophilic statin with a strong effect on lowering plasma total cholesterol and triacylglycerol. It has been reported to have pleiotropic effects such as decreasing inflammation and oxidative stress, regulating angiogenesis and osteogenesis, improving endothelial function and arterial stiffness, and reducing tumor progression. Based on the available studies considering the risk of statin-associated muscle symptoms it seems to be also the safest statin. The unique lipid and non-lipid effects of pitavastatin make this molecule a particularly interesting option for the management of different human diseases. In this review, we first summarized the lipid effects of pitavastatin and then strive to unravel the diverse pleiotropic effects of this molecule.
