Kim KJ, Yoon J, Won KH, Lim SW, Chae IH, Lee SY, Kim SW, Kim HS. Assessment of the Efficacy of Lowering LDL Cholesterol with Rosuvastatin 10 mg in Four Korean Statin Benefit Groups as per ACC/AHA Guidelines (NewStaR4G). J Clin Med 2020; 9:jcm9040916. [PMID: 32230818 PMCID: PMC7230727 DOI: 10.3390/jcm9040916] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 03/24/2020] [Accepted: 03/25/2020] [Indexed: 01/14/2023] Open
Abstract
The American College of Cardiology and American Heart Association (ACC/AHA) guidelines identified four statin benefit groups on the basis of atherosclerotic cardiovascular disease risk reduction and proposed statin therapy by evidence-based intensity. Although these guidelines used randomized controlled trials with hard outcomes as exclusive evidence for its recommendations, a limited number of studies conducted in Asian countries makes its application of treatment strategy, intensity, and statin doses uncertain in these population. This prospective, multicenter study aimed to evaluate the efficacy of rosuvastatin 10 mg in the four statin benefit groups requiring high- or moderate-intensity statin therapy according to the ACC/AHA guidelines in the Korean population. The primary endpoint was percentage reduction in low-density lipoprotein (LDL) cholesterol. Secondary endpoints were percentage reduction in other lipids and achievement of ≥50% reduction in LDL cholesterol. Rosuvastatin 10 mg lowered LDL cholesterol by 61.4 mg/dL, a 44.9% decrease from baseline after eight weeks. Reduction of LDL cholesterol ≥50% was achieved in 46.3% of patients. Rosuvastatin 10 mg was generally well tolerated. In the Korean population, rosuvastatin 10 mg was favorable and tolerant in lowering LDL cholesterol in the four statin benefit groups requiring high- or moderate-intensity statin therapy according to the ACC/AHA guidelines.

Abstract
Background and purpose: Bone regeneration can be accelerated by localized delivery of statins. Here, we aimed to evaluate the effect of two thermosensitive hydrogels containing rosuvastatin (RSV) on proliferation and differentiation of human osteoblast-like MG-63 cells. Experimental approach: Firstly, chitosan (CTS)/glycerophosphate (GP)/gelatin (G) thermosensitive hydrogel was prepared and characterized based on rheological properties, in vitro erosion, and release pattern of RSV and then the optimized mixture was loaded with nanoparticles containing RSV(NRSV). Secondly, the effect of NRSV-embedded in CTS/GP/G on cell viability, alkaline phosphate activity, and cell calcification was evaluated using MG-63 cells and compared with RSV-embedded into hyaluronic acid (HA)/Pluronic® F127 (PF127) hydrogel. Findings / Results: CTS/GP mixtures with 1 and 1.5 % gelatin existing in solution with low viscosity at 4 °C were solidified at 32-34 °C while the mixture containing 2% gelatin was jellified at room temperature. The gelation times of CTS/GP/G with 1 and 1.5% gelatin were 72 and 44 s, respectively. The hydrogel containing 3% w/v NRSV was also converted to a semisolid upon increasing the temperature to 33-36 °C. Due to the higher gel strength of CTS/GP/G compared to HA/PF127 hydrogel, the release rate of RSV from the NRSV-embedded CTS/GP/G hydrogel was significantly slower than that of HA/PF127 system. As revealed by alkaline phosphatase and mineralization assays, NRSV-embedded in CTS/GP/G hydrogel had the most promotive effect on differentiation of osteoblasts among other mixtures. Conclusion and implication: NRSV-embedded in CTS/GP/G hydrogel could be efficiently used in the future for bone defects such as osteoporosis and bone fractures.

Abstract
Background Rosuvastatin (RSV) is a poorly water-soluble drug that has an absolute oral bioavailability of only 20%. The aim of this work was to prepare a positively charged chitosan coated flexible lipid-based vesicles (chitosomes) and compare their characteristics to the corresponding negatively charged flexible liposomal nanoparticles (NPs) in order to develop new RSV nanocarrier systems. Methods Three formulation factors affecting the development of chitosomes nano-formulation were optimized for their effects on the particles size, entrapment efficiency (EE) and zeta potential. The optimized flexible chitosomes and their corresponding liposomal NPs were characterized for morphology, in vitro release, flexibility and intestinal cell viability. The half maximum inhibitory concentrations (IC50) for both formulations were calculated. Results The drug to lipid molar ratio, edge activator percent and the chitosan concentration were significantly affecting the characteristics of NPs. The optimized chitosomes nano-formulation exhibited larger size, higher EE and greater zeta potential value when compared to the corresponding liposomal NPs. Both formulations showed a spherical shape nanostructure with a marked outer shell for the chitosomes nano-formulation. Chitosomes illustrated an extended drug release profile when compared with the corresponding liposomal NPs and the prepared drug suspension. Flexibility of both vesicles was confirmed with superiority of liposomal NPs over chitosomes. RSV loaded chitosomes nano-formulation exhibited lower IC50 values and higher therapeutic window while liposomal NPs were compatible with the intestinal cells. Conclusions RSV loaded chitosomes nano-formulation could be considered as a promising nanocarrier system with a marked cytotoxic activity while, RSV loaded liposomal NPs are suitable nanocarrier to improve RSV activity in treatment of cardiovascular disorders.

Rosuvastatin suppresses cytokine production and lung inflammation in asthmatic, hyperlipidemic and asthmatic-hyperlipidemic rat models. Cytokine 2020; 128:154993. [PMID: 32007867 DOI: 10.1016/j.cyto.2020.154993] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 12/31/2019] [Accepted: 01/08/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Given the role that T lymphocytes play on the pathogenesis of allergic asthma, drugs targeting Th2 and Th17 cells may be a hopeful therapeutic strategy. This study aimed to evaluate the effect of rosuvastatin treatment on cytokine production and lung inflammation in allergic asthma. METHODS The animals were assigned into control (C), asthmatic (A), hyperlipidemic (H), asthmatic-hyperlipidemic (AH), rosuvastatin (40 mg/kg/day intraperitoneally, for 3 weeks)-treated asthmatic (AR), rosuvastatin-treated hyperlipidemic (HR) and rosuvastatin-treated asthmatic-hyperlipidemic (AHR) groups (n = 6 in each group). The levels of IL-4, IFN-γ and IL-17, total and differential WBC counts in bronchoalveolar lavage fluid (BALF), Th1/Th2 balance, and pathological changes were evaluated. RESULTS The BALF level of IL-4 in A, H and AH groups, and IL-17A in A and AH groups were significantly higher than that in C group (p < 0.05 to p < 0.001). IFN-γ level and Th1/Th2 balance (IFN‑γ/IL-4 ratio) in A and AH groups were significantly decreased (p < 0.05 to p < 0.01). Inflammatory cells infiltration, muscle hypertrophy and emphysema were also observed in A and AH groups. The BALF levels of IL-4 in AR, HR and AHR groups, IFN-γ level in HR group, and IL-17A level in AR and AHR groups showed a significant improvement compared to that of A, H and AH groups (p < 0.05 to p < 0.001). Rosuvastatin treatment increased Th1/Th2 balance in all treated groups (p < 0.05 to p < 0.01), decreased total WBC counts, neutrophilia, eosinophilia and lung inflammation in AR and AHR groups, and improved muscle hypertrophy and emphysema in AHR group. CONCLUSIONS Rosuvastatin treatment improved lung pathological changes by suppression of Th2 and Th17-mediated cytokines which was unrelated to its lipid-lowering activity. Therefore, rosuvastatin might be a candidate immunomodulatory drug for treatment of patients with allergic asthma.

Rosuvastatin and retinoic acid may act as 'pleiotropic agents' against β-adrenergic agonist-induced acute myocardial injury through modulation of multiple signalling pathways. Chem Biol Interact 2020; 318:108970. [PMID: 32007421 DOI: 10.1016/j.cbi.2020.108970] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Revised: 01/18/2020] [Accepted: 01/29/2020] [Indexed: 12/26/2022]
Abstract
Cardiovascular disorders constitute the principal cause of deaths worldwide and will continue as the major disease-burden by the year 2060. A significant proportion of heart failures occur because of use and misuse of drugs and most of the investigational agents fail to achieve any clinical relevance. Here, we investigated rosuvastatin and retinoic acid for their "pharmacological pleiotropy" against high dose β-adrenergic agonist (isoproterenol)-induced acute myocardial insult. Rats were pretreated with rosuvastatin and/or retinoic acid for seven days and the myocardial injury was induced by administering isoproterenol on the seventh and eighth day. After induction, rats were anaesthetized for electrocardiography, then sacrificed and different samples were collected/stored for various downstream assays. Myocardial injury with isoproterenol resulted in increased cardiac mass, decreased R-wave amplitude, increased QRS and QT durations; elevated levels of cardiac markers like cTnI, CK-MB, ALT and AST; increased lipid peroxidation, protein carbonylation and tissue nitric oxide levels; decreased endogenous antioxidants like SOD, CAT, GR, GST, GPx and total antioxidant activity; increased inflammatory markers like TNF-α and IL-6; decreased the mRNA expression of Nrf2 and Bcl-2; increased the mRNA expression of Bax, eNOS and iNOS genes. Pretreatment with rosuvastatin and/or retinoic acid mitigated many of the above biochemical and pathological alterations. Our results demonstrate that rosuvastatin and retinoic acid exert cardioprotective effects and may act as potential agents in the prevention of β-adrenergic agonist-induced acute myocardial injury in rats. Cardioprotective potential of rosuvastatin and retinoic acid could be attributed to their influence on the redox pathways, immunomodulation, membrane stability, Nrf2 preservation, iNOS and Bax expression levels. Thus, they may act directly or indirectly at various steps, the breakpoints, in the pathophysiological cascade responsible for cardiac injury. Our study gives insights about the pharmacological pleiotropism of rosuvastatin and retinoic acid.

Abstract
Rosuvastatin, known as a cholesterol-lowering agent, has been used as an alternative therapy after the onset of stroke. In this study, neuroprotection and functional recovery of exosomes in combination with rosuvastatin have been investigated. Sixty adult male Wistar rats were subjected to middle cerebral artery occlusion (MCAO). Exosome at the dose of 100 μg and/or rosuvastatin at the dose of 20 mg/kg/day for 7 days were administered to rats as a therapeutic strategy. The elevated body swing test (EBST) and Garcia score were conducted as behavioral tests for the measurement of functional recovery. The histopathological and immunohistochemical analyses were also performed for the assessment of infarcted volume and neuroprotection in the brain of rats. The real-time PCR method was carried out to determine the relative expressions of the NLRP-3 and NLRP1 genes. After 7 days of treatment with exosome and rosuvastatin in rats which underwent MCAO, the decrease in infarct volume of the animals treated with exosome was more pronounced compared with those treated only with exosome. The combination therapy remarkably lowered the size of infarct volume. Our observation was confirmed by the downregulation of the NLRP1 and NLRP3 genes in response to combinatory treatment of rats induced by MCOA, denoting a lower rate of cell death. The number of GFAP-positive cells were reduced in the exosome-treated group compared with the MCAO group. The rate of lipid peroxidation was measured by malondialdehyde (MDA) levels which demonstrated a significant reduction of MDA in the exosome- and rotuvastatin-treated groups when compared with the MCAO group. However, the levels of the SOD enzyme did not significantly alter when the treatment groups were compared with the MCAO group. According to our findings, it seems that the use of exosomes and rosuvastatin, as a novel treatment regimen, might promote neurological recovery after the onset of stroke.

Abstract
The cardioprotective activity of rosuvastatin (R) is yet to be known. The objective of this study was to research whether R perfusion before global ischemia can mitigate myocardial ischemia-reperfusion damage, considering the metabolic condition in which these effects occur, and to contemplate potential mitochondrial benefits. Protein kinase B (Akt)/glycogen synthase kinase-3β (GSK-3β) and mitochondrial permeability transition pore (MPTP) are key elements in myocardial injury produced by ischemia-reperfusion. Isolated rat hearts were subjected to 25-min ischemia and 1-h reperfusion in the presence or absence of R, with or without Wortmannin (W), a phosphatidylinositol 3-kinase (PI3K)/Akt inhibitor. Akt and GSK-3β were measured by Western blot analysis; lactate, glycogen, and G6PDH were determined; and Ca2+-induced MPTP opening was evaluated using a spectrophotometric method. Contractility was assessed by left ventricular developed pressure (LVDP), and rate-pressure product (RPP), peak rate of contraction and peak rate of relaxation (± dP/dt), and left ventricular end-diastolic pressure (LVEDP) were determined. Tissue samples were extracted to evaluate mitochondrial damage by electron microscopy and to assess infarct size. Statistical analysis employed ANOVA (n = 6/per group). Myocardial infarct size was significantly reduced by R, which also improved cardiac function. MPTP opening was delayed to 300 μM CaCl2, while use of W resulted in MPTP opening at 200 μM CaCl2. Electron microscopy showed better mitochondrial preservation with R, which reduced lactic acid production, increased glycogen consumption and G6PDH activity, as well as phosphorylation of Akt and GSK-3β. R before ischemia is cardioprotective against ischemic and reperfusion damage, activating Akt and regulating GSK-3β negatively and attenuating the MPTP opening.

Abstract
PURPOSE Impaired antiplatelet effect of clopidogrel (CLP) can result from drug-drug interactions and genetic polymorphisms of drug-metabolizing enzymes. The aim of the study was to evaluate the effect of genetic polymorphisms of ABCB1 and the selected cytochrome P450 isoenzymes on the pharmacodynamics and pharmacokinetics of CLP and its metabolites in patients co-treated with atorvastatin or rosuvastatin. METHODS The study involved 50 patients after coronary angiography/angioplasty treated with CLP and atorvastatin (n = 25) or rosuvastatin (n = 25) for at least 6 months. Plasma concentrations of CLP, diastereoisomers of thiol metabolite (inactive H3 and active H4), and inactive CLP carboxylic acid metabolite were measured by UPLC-MS/MS method. Identification of the CYP2C19*2, CYP2C19*17, CYP3A4*1G, CYP1A2*1F, and ABCB1 C3435T genetic polymorphisms was performed by PCR-RFLP, while platelet reactivity units (PRU) were tested using the VerifyNow P2Y12 assay. RESULTS There were significant differences in the pharmacokinetic parameters of the H4 active metabolite of CLP in the atorvastatin and rosuvastatin group divided according to their CYP2C19 genotype. There were no significant associations between CYP3A4, CYP1A2, and ABCB1 genotypes and pharmacokinetic parameters in either statin groups. In the multivariate analysis, CYP2C19*2 genotype and non-genetic factors including BMI, age, and diabetes significantly affected platelet reactivity in the studied groups of patients (P < 0.01). In the atorvastatin group, CYP2C19*2, CYP3A4*1G, and ABCB1 C3435T TT genotypes were independent determinants of PRU values (P < 0.01). CONCLUSION The CYP2C19*2 allele is the primary determinant of the exposition to the H4 active metabolite of clopidogrel and platelet reactivity in patients co-treated with atorvastatin or rosuvastatin.

Abstract
Background There is no randomized clinical trials with recurrence of atherosclerotic cardiovascular disease (ASCVD) as a major outcome with rosuvastatin. In order to analyze potential differences in the clinical response to atorvastatin and rosuvastatin in secondary ASCVD prevention, we have analyzed the clinical evolution of those subjects of the Dyslipemia Registry of the Spanish Society of Arteriosclerosis (SEA) who at the time of inclusion in the Registry had already suffered an ASCVD. Methods This observational, retrospective, multicenter, national study was designed to determine potential differences between the use of atorvastatin and rosuvastatin in the ASCVD recurrence. Three different follow-up start-times were performed: time of inclusion in the registry; time of first event if this occurred after 2005, and time of first event without date restriction. Results Baseline characteristics were similar between treatment groups. Among atorvastatin or rosuvastatin users, 89 recurrences of ASCVD were recorded (21.9%), of which 85.4% were coronary. At the inclusion of the subject in the registry, 345 participants had not suffered a recurrence yet. These 345 subjects accumulated 1050 person-years in a mean follow-up of 3 years. Event rates were 2.73 (95% CI: 1.63, 4.25) cases/100 person-years and 2.34 (95% CI: 1.17, 4.10) cases/100 person-years in the atorvastatin and rosuvastatin groups, respectively. There were no statistically significant differences between the two groups independently of the follow-up start-time. Conclusions This study does not find differences between high doses of rosuvastatin and atorvastatin in the recurrence of ASCVD, and supports their use as clinically equivalent in secondary prevention of ASCVD.

Abstract
BACKGROUND & AIM Schizophrenia is a chronic, disabling neurological illness. This study investigated the effect of rosuvastatin (RSU) addition to the antipsychotic drug: olanzapine (OLZ) in treatment of post-weaning isolation rearing (IR) damaging effect and assessed behavioral impairment, metabolic and hepatic abnormalities, oxidative stress, and inflammatory markers. METHODS Treatment with OLZ (6 mg/kg, P.O.) and/or RSU (10 mg/kg, I.P.) have been started 6 weeks after isolation. We assessed behavioral tests, serum cortisol level, and hippocampal content of neurotransmitters. In addition, we assessed histopathology, inflammatory and oxidative stress markers of hippocampus, liver and adipose tissue RESULTS: Treatment of IR animals with OLZ, and/or RSU significantly counteracted the changes in hippocampus, liver and adipose tissue induced by post-weaning IR. Co-treatment of IR rats with both OLZ and RSU showed additive effects in some areas like improving both tumor necrosis factor alpha (TNFα) in both hippocampus and liver, histopathology of liver, oxidative stress markers of adipose tissue, β3 adrenergic receptors (ADRβ3), serum cortisol and total cholesterol. In addition, RSU alone alleviated the damage of IR rats by the same efficacy as OLZ with more benefit in cognition and exploration. CONCLUSION post-weaning IR as a model has behavioral, hippocampal, hepatic and marked metabolic changes more relevant to schizophrenia than drug-induced models. These effects were ameliorated by RSU and/or OLZ that are explained by their antioxidant, anti-inflammatory, anti-stress and anti-hyperlipidemic properties. Interestingly, co-treatment with both drugs showed a better effect.

Abstract
Statins provide greater protection than predicted from just cholesterol-lowering effects, which is possibly mediated by other pleiotropic actions. This study aimed to examine the possible interaction effect of asthma on lipid profiles and evaluate the effect of rosuvastatin treatment on asthma. The animals were assigned into (1) control, (2) asthmatic, (3) hyperlipidemic, (4) asthmatic-hyperlipidemic, (5) rosuvastatin (40 mg/kg/day intraperitoneally, for 3 weeks)-treated asthmatic, (6) rosuvastatin-treated hyperlipidemic and (7) rosuvastatin-treated asthmatic-hyperlipidemic groups. Tracheal responsiveness to methacholine and ovalbumin, total and differential WBC (white blood cell) counts, and oxidative stress markers in bronchoalveolar lavage fluid (BALF) were evaluated. In the asthmatic and asthmatic-hyperlipidemic groups, tracheal responsiveness to ovalbumin, total WBC count, numbers of eosinophils, neutrophils, and monocytes were higher than the control group (p<0.001). A left-ward shift in the concentration-response curves to methacholine, an increase in nitrite and malondialdehyde concentrations, and a decrease in total thiol content, superoxide dismutase and catalase activities were also observed in the asthmatic and asthmatic-hyperlipidemic groups compared to control group (p<0.01 to p<0.001). Beyond lipid-lowering effect in the treated hyperlipidemic and asthmatic-hyperlipidemic groups, rosuvastatin treatment decreased tracheal responsiveness to methacholine, reduced total WBC count, the numbers of eosinophils, neutrophils, and monocytes, as well as decreased malondialdehyde concentration, and increased total thiol content, superoxide dismutase and catalase activities in treated asthmatic and asthmatic-hyperlipidemic groups (p<0.05 to p<0.001). The improving effect of rosuvastatin on asthmatic and asthmatic-hyperlipidemic animals was shown due to pleiotropic mechanisms including the effect on airway hyperresponsiveness, lung inflammation, and oxidative stress.

Abstract
Drug-induced liver injury (DILI) is among the challenging liver conditions encountered by clinicians today. It has a low incidence in the general population with an approximated annual incidence of 10 - 15 cases per 10,000 - 100,000 persons who have taken prescription medications. Nevertheless, DILI remains the most frequent cause of acute liver injury in the United States. Rosuvastatin is a commonly prescribed medication that, similar to other statins, is associated with serum aminotransferase elevations that are mild, asymptomatic and usually self-limited. Here, we report a case of a man who developed acute liver injury after taking rosuvastatin for hypercholesterolemia treatment. Moreover, DILI with autoimmune features represents a key subgroup of hepatotoxicity attributable to medication exposure. Similar to idiopathic autoimmune hepatitis, circulating autoantibodies and a hypergammaglobulinemia are often present in the serum of such individuals. However, such findings are not invariable. In the case reported here, these laboratory features were absent, but a liver biopsy demonstrated interface hepatitis with a prominent plasma cell infiltrate, histologic components consistent with an immune-mediated drug reaction. After withdrawal of the offending medication did not result in complete resolution, corticosteroid therapy was administered with a subsequent clinical response, confirming the diagnosis.

Abstract
Aim: Most statins increase the risk of new-onset diabetes. Unlike other statins, pitavastatin is reported to exert neutral effects on serum glucose level, but the precise mechanism is unknown. Methods: Eight-week-old male C57BL/6J mice (n = 26) were fed high-fat diet (HFD, 45% fat) with 0.01% placebo, rosuvastatin, or pitavastatin for 12 weeks. Cultured HepG2, C2C12, and 3T3-L1 cells and visceral adipocytes from HFD-fed mice were treated with vehicle or 10 µM statins for 24 h. The effects of pitavastatin and rosuvastatin on intracellular insulin signaling and glucose transporter 4 (GLUT4) translocation were evaluated. Results: After 12 weeks, the fasting blood glucose level was significantly lower in pitavastatin-treated group than in rosuvastatin-treated group (115.2 ± 7.0 versus 137.4 ± 22.3 mg/dL, p = 0.024). Insulin tolerance significantly improved in pitavastatin-treated group as compared with rosuvastatin-treated group, and no significant difference was observed in glucose tolerance. Although plasma adiponectin and insulin levels were not different between the two statin treatment groups, the insulin-induced protein kinase B phosphorylation was weakly attenuated in pitavastatin-treated adipocytes than in rosuvastatin-treated adipocytes. Furthermore, minor attenuation in insulin-induced GLUT4 translocation to the plasma membrane of adipocytes was observed in pitavastatin-treated group. Conclusion: Pitavastatin showed lower diabetogenic effects than rosuvastatin in mice that may be mediated by minor attenuations in insulin signaling in adipocytes.

Abstract
INTRODUCTION Amlodipine, valsartan, and rosuvastatin are among the medications widely coadministered for the treatment of hyperlipidemia accompanied by hypertension. The aim of this study was to investigate the possible pharmacokinetic drug-drug interactions between amlodipine, valsartan, and rosuvastatin in healthy Korean male volunteers. METHODS In this phase 1, open-label, multiple-dose, two-part, two-period, fixed-sequence study, the enrolled subjects were randomized into two parts (A and B). In part A (n = 32), each subject received one fixed-dose combination (FDC) tablet of amlodipine/valsartan 10 mg/160 mg alone for 10 consecutive days in period I, and the same FDC for 10 days with concomitant 7-day administration of 20 mg rosuvastatin in period II. In part B (n = 25), each subject received rosuvastatin alone for 7 days in period I, and the FDC for 10 days with concomitant 7-day administration of rosuvastatin in period II. In both parts, there was a 12-day washout between periods. Serial blood samples were collected for up to 72 h for amlodipine and rosuvastatin, and for up to 48 h for valsartan after the last dose of each period. The plasma concentrations of amlodipine, valsartan, and rosuvastatin were determined by using liquid chromatography-tandem mass spectrometry. RESULTS Fifty-seven subjects were enrolled; 30 and 25 subjects completed part A and part B, respectively. The geometric mean ratios and 90% confidence intervals for the maximum plasma concentration at steady state (Cmax,ss) and the area under the plasma concentration-time curve over the dosing interval at steady state (AUCτ,ss) were 0.9389 (0.9029-0.9763) and 0.9316 (0.8970-0.9675) for amlodipine, 0.7698 (0.6503-0.9114) and 0.7888 (0.6943-0.8962) for valsartan, and 0.9737 (0.8312-1.1407) and 0.9596 (0.8826-1.0433) for rosuvastatin, respectively. Of the 57 subjects enrolled in this study, 10 subjects experienced 13 adverse events (AEs); no severe or serious AEs were reported. CONCLUSION When amlodipine, valsartan, and rosuvastatin were coadministered to healthy volunteers, the pharmacokinetic exposure to valsartan was decreased, but no change in exposure to amlodipine and rosuvastatin occurred. All treatments were well tolerated. CLINICAL TRIAL REGISTRATION https://cris.nih.go.kr CRIS KCT0001660. FUNDING KyungDong Pharmaceutical Corp. Ltd., Seoul, Republic of Korea.

A randomized unblinded trial to compare effects of intensive versus conventional lipid-lowering therapy in patients undergoing renal artery stenting. J Cardiol 2019; 74:443-450. [PMID: 31235418 DOI: 10.1016/j.jjcc.2019.04.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2018] [Revised: 03/24/2019] [Accepted: 04/24/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Although current guidelines recommend the use of statins for severe atherosclerotic renal artery stenosis (ARAS), the renal protection of intensive lipid-lowering therapy in patients with ARAS who underwent stent placement remains uncertain. The aim of this study was to compare the renal-protective effect of intensive lipid lowering with that of conventional lipid lowering in patients with ARAS undergoing stent placement. METHODS A total 150 patients with severe ARAS undergoing stent placement were randomly (1:1) assigned to receive intensive lipid lowering [target low-density lipoprotein cholesterol (LDL-C) <70mg/dL] or conventional lipid lowering (target LDL-C ≥70mg/dL, <128mg/dL). All patients received rosuvastatin. We adjusted LDL-C to the goal within two months after renal stenting and maintained stability. The primary endpoint was the change in estimated glomerular filtration rate (eGFR) at 12 months. RESULTS During the study period, LDL-C was lower in the patients with intensive lipid lowering than with conventional lipid lowering (at 12 months 58.0±11.6 vs 85.1±15.5mg/dL, p<0.001). At 12-month follow-up, eGFR (91.8±30.2 vs 78.5±19.5)mL/min·1.73m2, p=0.002) and the increase in eGFR compared to baseline [14.8(IQR, 4.1, 26.7) vs -0.4(IQR, -9.5, 8.0)mL/min·1.73m2, p<0.001] were higher in the patients with intensive lipid lowering than with conventional lipid lowering. Urinary albumin-creatinine ratio [42.2(IQR, 20.0, 60.9) vs 60.8(IQR, 26.8, 121.6)mg/g, p=0.032] was lower and the decrease in urinary albumin-creatinine ratio compared to baseline [27.4(IQR, 3.0, 53.8) vs -3.1(IQR, -17.3, 30.9)mg/g, p=0.001] was higher in the patients with intensive lipid lowering than with conventional lipid lowering. The restenosis rate (3.1% vs 3.4%, p=0.711) and major clinical events (6.8% vs 11.0%, p=0.37) were similar between the two groups. CONCLUSIONS In patients with severe ARAS undergoing stent placement, intensive lipid lowering showed significant benefits in renal protection over conventional lipid-lowering therapy.

Influence of statin treatment on pharmacokinetics and pharmacodynamics of clopidogrel and its metabolites in patients after coronary angiography/angioplasty. Biomed Pharmacother 2019; 116:108991. [PMID: 31136946 DOI: 10.1016/j.biopha.2019.108991] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Revised: 04/30/2019] [Accepted: 05/13/2019] [Indexed: 11/19/2022] Open
Abstract
Possible interaction between clopidogrel and CYP3A4-metabolised atorvastatin or non-CYP3A4-metabolised rosuvastatin was investigated based on pharmacokinetic parameters of clopidogrel and its metabolites as well as the platelet reactivity test in patients undergoing coronary angiography/angioplasty. The study involved 50 patients (62.7 ± 7.8 years old) who underwent coronary angiography/angioplasty and were treated with clopidogrel and atorvastatin or rosuvastatin during the six months after the procedure. The P2Y12 reaction units (PRU) and pharmacokinetic parameters of clopidogrel, diastereoisomers of thiol metabolite (inactive H3 and active H4), and inactive carboxylic metabolite were measured 12-18 h and six months after the coronary angiography/angioplasty. There were no significant differences in concentrations of clopidogrel and its metabolites including the H4 active metabolite in plasma of patients co-treated with clopidogrel and atorvastatin or rosuvastatin. The use of statins did not affect the pharmacokinetic parameters of the studied compounds. A significant correlation was found between the Cmax and AUC0-t of the active H4 isomer and platelet aggregation in a group of patients treated with rosuvastatin but not in the atorvastatin group. No significant differences in PRU values were observed between the atorvastatin and rosuvastatin groups at the beginning of the study (171.4 ± 54.3 vs 146.3 ± 48.1 PRU, p = 0.192) as well as at six months (173.7 ± 45.8 vs 157.3 ± 54.9 PRU, p = 0.562). However, in a small group of patients, who were discharged from atorvastatin to rosuvastatin, an increase in the PRU values accompanied by a decreased AUC of the H4 active isomer was observed. The study confirmed that the systemic exposure to clopidogrel and its active H4 isomer of thiol metabolite, as well as the antiplatelet effect of the drug, were not negatively affected by co-administration of atorvastatin as compared with rosuvastatin.

Abstract
The objective was to use caffeine and Soluplus® to improve the dissolution rate and to maintain a concentration of BCS Class II rosuvastatin calcium that exceeds its solubility. Caffeine and Soluplus® together substantially improved the dissolution rate and the extent of rosuvastatin release. Formulations for direct compression tablets included Formulation F1, a control with drug but with neither caffeine nor Soluplus® present; F2 with drug-caffeine complex; F3 with drug and Soluplus® and F4 with drug-caffeine complex and Soluplus®. Each formulation blend provided satisfactory flow properties. Tablets were comparable in mass, hardness and friability. A marked decrease in disintegration time occurred when the hydrotropic or micellar agent was included in the formulation. Assay (98–100%) and content uniformity (99–100%) results met requirements. Release studies in pH 1.2, 6.6, and 6.8 buffers revealed the superiority of F4. At 45 min sampling time, F3 and F4 tablets each provided a cumulative drug release greater than 70% in each medium. F2 tablets exhibited compliance to official standards in pH 6.6 and 6.8 buffers but not in pH 1.2 buffer, whereas tablets based on F1 failed in each medium. Two-factor ANOVA of the release data revealed a statistical difference across the four formulations in each release medium. Pairwise comparison of release profiles demonstrated that, of the four formulations, F4 provided the most effectively enhanced dissolution rate, improvement to the extent of drug release and support of a concentration higher than the solubility of rosuvastatin calcium.

Rosuvastatin improves the FGF19 analogue NGM282-associated lipid changes in patients with non-alcoholic steatohepatitis. J Hepatol 2019; 70:735-744. [PMID: 30529590 DOI: 10.1016/j.jhep.2018.11.032] [Citation(s) in RCA: 57] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Revised: 10/28/2018] [Accepted: 11/27/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND NGM282, an engineered analogue of the gut hormone FGF19, improves hepatic steatosis and fibrosis biomarkers in patients with non-alcoholic steatohepatitis (NASH). However, NGM282 increases serum cholesterol levels by inhibiting CYP7A1, which encodes the rate-limiting enzyme in the conversion of cholesterol to bile acids. Herein, we investigate whether administration of a statin can manage the cholesterol increase seen in patients with NASH receiving treatment with NGM282. METHODS In this phase II, open-label, multicenter study, patients with biopsy-confirmed NASH were treated with subcutaneous NGM282 once daily for 12 weeks. After 2 weeks, rosuvastatin was added in stepwise, biweekly incremental doses to a maximum of 40 mg daily. Both drugs were continued until the end of treatment at week 12. We evaluated plasma lipids, lipoprotein particles and liver fat content. RESULTS In 66 patients who received NGM282 0.3 mg (n = 23), NGM282 1 mg (n = 21), or NGM282 3 mg (n = 22), circulating cholesterol increased from baseline at week 2. Initiation of rosuvastatin resulted in rapid decline in plasma levels of total cholesterol and low-density lipoprotein cholesterol. At week 12, reductions from baseline in total cholesterol levels of up to 18% (p <0.001), low-density lipoprotein cholesterol of up to 28% (p <0.001), triglycerides of up to 34% (p <0.001) and an increase in high-density lipoprotein cholesterol of up to 16% (p <0.001), with similar changes in lipoprotein particles, were observed in these patients. Robust decreases from baseline in 7alpha-hydroxy-4-cholesten-3-one (p <0.001) and liver fat content (p <0.001) were also observed. Rosuvastatin was safe and well-tolerated when co-administered with NGM282 in patients with NASH. CONCLUSIONS In this multicenter study, NGM282-associated elevation of cholesterol was effectively managed with rosuvastatin. Co-administration of rosuvastatin with NGM282 may be a reasonable strategy to optimize the cardiovascular risk profile in patients with NASH. LAY SUMMARY Non-alcoholic steatohepatitis (NASH) represents a large and growing public health concern with no approved therapy. NGM282, an engineered analogue of the gut hormone FGF19, reduces liver fat, liver injury and inflammation in patients with NASH. However, NGM282 increases cholesterol levels. Here we show that co-administration of a statin can manage the cholesterol increase seen in patients with NASH receiving treatment with NGM282, producing a favorable overall lipid profile.

Abstract
Objective: To investigate the effects of rosuvastatin (RSV)on autophagy and apoptosis of myocardial cells in rats with acute myocardial infarction. Methods: SD rats were divided into control (Sham group), acute myocardial infarction model rats (AMI group), AMI rats treated by RSV with the dose of 5 mg·kg(-1)·d(-1) (RSV group), AMI rats treated by RSV and AMPK inhibitor Compound C at the same time (RSV+ CC group)(n=8) based on simple random sampling methods.Rat myocardial cell line H9c2 was divided into control group, Hypoxia group, Hypoxia+ RSV group, Hypoxia+ RSV+ Compound C group, Hypoxia+ AICAR (AMPK activator)group.After 6 weeks, the rats were examined by hemodynamics, and pathological observation of myocardial tissue by HE staining was also carried out.RT-PCR/Western blot were used to detect the expression of Beclin1, p62, BAX and Bcl-2 mRNA or protein of different groups in vivo and in vitro.Western blot was used to detect the expression of mTOR and AMPK protein and phosphorylation in cardiac tissue of each group. Results: In this study, the rat model of acute myocardial infarction was successfully prepared.Compared with the AMI group, the myocardium inflammation in the RSV group was alleviated, the LVMI decreased significantly, LVSP increased significantly, LVEDP decreased significantly, HR decreased significantly, the absolute value of dP/dTmax and -dP/dTmax increased significantly.The levels of Beclin1 and Bcl-2 mRNA were significantly up-regulated from 0.43 to 2.01 and 0.30 to 0.72, the expression of p62 and BAX mRNA decreased in half, the phosphorylation level of AMPK was significantly up-regulated, and the level of mTOR phosphorylation significantly reduced(P<0.05). These changes were antagonized by AMPK inhibitors in RSV+ CC group.In vitro experiments showed that, after RSV intervening, the levels of Beclin1 and Bcl-2 mRNA and protein in the myocardial cells of Hypoxia group significantly increased in triple, while the expressions of p62 and BAX mRNA and protein significantly decreased above a half.The above changes were consistent with those of the AMPK activator group and were antagonized by Compound C. Conclusion: RSV can effectively promote autophagy and decrease apoptosis in rat heart after myocardial infarction through AMPK/mTOR pathway.

Abstract
Background In the South African private sector context, generically similar products are grouped together and the reimbursement rate is set at the average price of the generically equivalent products. Very little evidence exists in low and middle-income countries with regards to the impact of this policy over time. Objectives To determine the impact of the introduction of generics and generic reference pricing on candesartan and rosuvastatin in the South African private health care sector in terms of medicine utilisation, medicine price and medicine expenditure. Setting South African private health sector. Method Medicine claims for candesartan and rosuvastatin was obtained from a Pharmacy Benefit Manager in South Africa. The claims covered a 48-month period from January 2012 to December 2015 and provided a pre- and post-reference price period for analysis. Medicine utilisation was measured as the number of Defined Daily Doses dispensed per 100,000 beneficiaries. Medicine price and expenditure was calculated as the average per Defined Daily Dose. Main outcome measure Medicine utilisation, price and expenditure. Results Candesartan experienced an average 7.0% year-on-year decline in utilisation and rosuvastatin a 5.0% increase. Medicine expenditure reduced by an additional 34.6% and 20.9% for candesartan and rosuvastatin respectively. The total savings was 54.8% for candesartan and 31.9% for rosuvastatin. Conclusion The introduction of generics and generic reference pricing did not have an impact on medicine utilisation, but reduced the price and expenditure of both candesartan and rosuvastatin.

Abstract
Background HMG-CoA reductase inhibitors (statins) are the first-choice therapy for primary prevention of cardiovascular disease. Some maintain that statins cause adverse musculoskeletal outcomes in highly active individuals, but few studies have examined the effects of statins on exercise-related injuries. Objective We sought to compare the prevalence of exercise-related injuries between runners who do or do not use statins. Methods Amateur runners (n = 4460) completed an extensive online questionnaire on their exercise patterns and health status. Participants replied to questions on the prevalence of exercise-related injuries in the previous year. Injuries were divided into general injuries, tendon- and ligament-related injuries, and muscle-related injuries. Participants were also queried about statin use: the type of statin, statin dose, and duration of treatment. Runners were divided into statin users, non-statin users with hypercholesterolemia, and controls for analysis. Results The crude odds ratios (ORs) for injuries, tendon- or ligament-related injuries, and muscle-related injuries in statin users compared with controls were 1.14 (95% confidence interval [CI] 0.79–1.66), 1.10 (95% CI 0.71–1.72), and 1.15 (95% CI 0.69–1.91), respectively. After adjustment for age, sex, body mass index (BMI), and metabolic equivalent of task (MET) h/week of exercise, the ORs were 1.11 (95% CI 0.76–1.62), 1.06 (95% CI 0.68–1.66), and 0.98 (95% CI 0.58–1.64), respectively. Similar effect measures were found when comparing non-statin users with hypercholesterolemia and controls. Conclusion We did not find an association between statin use and the prevalence of exercise-related injuries or tendon-, ligament-, and muscle-related injuries. Runners receiving statins should continue normal physical activity without concern for increased risk of injuries.

Abstract
Statins, HMG-CoA reductase inhibitors, are considered the first line treatment of hyperlipidemia to reduce the risk of atherosclerotic cardiovascular diseases. The prevalence of hyperlipidemia and the risk of atherosclerotic cardiovascular diseases are higher in obese patients. Published methods for the quantification of statins and their active metabolites did not test for matrix effect of or validate the method in hyperlipidemic plasma. A sensitive, specific, accurate, and reliable LC-MS/MS method for the simultaneous quantification of simvastatin (SMV), active metabolite of simvastatin acid (SMV-A), atorvastatin (ATV), active metabolites of 2-hydroxy atorvastatin (2-OH-ATV), 4-hydroxy atorvastatin (4-OH-ATV), and rosuvastatin (RSV) was developed and validated in plasma with low (52-103 mg/dl, <300 mg/dl) and high (352-403 mg/dl, >300 mg/dl) levels of triglyceride. The column used in this method was ACQUITY UPLC BEH C18 column (2.1 × 100 mm I.D., 1.7 μm). A gradient elution of mobile phase A (10 mM ammonium formate and 0.04% formic acid in water) and mobile phase B (acetonitrile) was used with a flow rate of 0.4 ml/min and run time of 5 min. The transitions of m/z 436.3 → 285.2 for SMV, m/z 437.2 → 303.2 for SMV-A, m/z 559.2 → 440.3 for ATV, m/z 575.4 → 440.3 for 2-OH-ATV and 4-OH-ATV, m/z 482.3 → 258.1 for RSV, and m/z 412.3 → 224.2 for fluvastatin (internal standard, IS) were determined by Selected Reaction Monitoring (SRM) method to detect transitions ions in the positive ion mode. The assay has a linear range of 0.25 (LLOQ) -100 ng/ml for all six analytes. Accuracy (87-114%), precision (3-13%), matrix effect (92-110%), and extraction recovery (88-100%) of the assay were within the 15% acceptable limit of FDA Guidelines in variations for plasma with both low and high triglyceride levels. The method was used successfully for the quantification of SMV, ATV, RSV, and their active metabolites in human plasma samples collected for an ongoing clinical pharmacokinetic and pharmacodynamic study on patients prior to and post gastric bypass surgery (GBS).

Abstract
Background Cluster of differentiation 40 ligand (CD40L) and rosuvastatin (RSV) affect atherosclerotic plaque stability, but little is known about their roles in extracellular matrix (ECM) production. We investigated the effects of CD40L and RSV on pre-existing advanced plaques. Methods and results Pre-existing advanced plaques were induced in apolipoprotein E-knockout (ApoE-/-) mice by the surgical placement of carotid constrictive silastic collars. Two weeks after surgery, mice were divided into the following treatment groups: control, empty adenovirus, CD40L adenovirus, CD40L adenovirus + RSV, and RSV. Mice received adenovirus via two tail-vein injections (2 × 109 pfu each) and/or RSV via intragastric administration (5 mg/kg; daily for 4 weeks). Mice in the CD40L adenovirus group exhibited increased plaque disruption rates, increased relative plaque macrophage and lipid content, reduced plaque collagen content, and increased local inflammation compared to the other treatment groups, but no significant differences in plaque area were observed among the groups. Notably, in the atherosclerotic plaques of the CD40L adenovirus group, both the mRNA and protein expression of prolyl-4-hydroxylase alpha 1 (P4Hα1) was significantly decreased, leading to a consequent decrease in the protein expression of collagen types I and III. Treatment with RSV decreased the serum levels of CD40L in a lipid-independent fashion and attenuated the effects of CD40L overexpression, particularly with respect to P4Hα1 downregulation. Conclusions CD40L destabilized advanced plaques in the carotid arteries of ApoE-/- mice, in part by decreasing P4Hα1 expression, and consequently collagen expression. These destabilizing effects were attenuated by RSV.

Abstract
X-linked adrenoleukodystrophy (X-ALD) is an inherited neurometabolic disorder caused by disfunction of the ABCD1 gene, which encodes a peroxisomal protein responsible for the transport of the very long-chain fatty acids from the cytosol into the peroxisome, to undergo β-oxidation. The mainly accumulated saturated fatty acids are hexacosanoic acid (C26:0) and tetracosanoic acid (C24:0) in tissues and body fluids. This peroxisomal disorder occurs in at least 1 out of 20,000 births. Considering that pathophysiology of this disease is not well characterized yet, and glial cells are widely used in studies of protective mechanisms against neuronal oxidative stress, we investigated oxidative damages and inflammatory effects of vesicles containing lecithin and C26:0, as well as the protection conferred by N-acetyl-L-cysteine (NAC), trolox (TRO), and rosuvastatin (RSV) was assessed. It was verified that glial cells exposed to C26:0 presented oxidative DNA damage (measured by comet assay and endonuclease III repair enzyme), enzymatic oxidative imbalance (high catalase activity), nitrative stress [increased nitric oxide (NO) levels], inflammation [high Interleukin-1beta (IL-1β) levels], and induced lipid peroxidation (increased isoprostane levels) compared to native glial cells without C26:0 exposure. Furthermore, NAC, TRO, and RSV were capable to mitigate some damages caused by the C26:0 in glial cells. The present work yields experimental evidence that inflammation, oxidative, and nitrative stress may be induced by hexacosanoic acid, the main accumulated metabolite in X-ALD, and that antioxidants might be considered as an adjuvant therapy for this severe neurometabolic disease.

Life Sci 2018; 213:248-257. [PMID: 30292831 DOI: 10.1016/j.lfs.2018.10.002] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2018] [Revised: 09/20/2018] [Accepted: 10/03/2018] [Indexed: 01/01/2023]
Abstract
PURPOSE Statins extended their hypocholestremic effect to show a promising anticancer activity. Hepatocellular carcinoma (HCC), the third common cause of cancer-related death, responded positively to statins. Some in-vitro studies reveal the rosuvastatin antitumor effect, but barely in-vivo studies. Hence, we evaluated the antitumor potential of rosuvastatin in a HCC model, the possible signaling cues involved, and whether it augments the dasatinib anticancer effect. METHOD For the in-vitro study, the IC50 and the combination (CI)/dose reduction (DRI) indices were determined for HCC cell line (HepG2) treated with dasatinib and/or rosuvastatin. For the in-vivo study, mice with diethylnitrosamine-induced HCC were treated for 21 days with dasatinib and/or rosuvastatin (10 and 20 mg/kg, respectively). The p-focal adhesion kinase/p-rous sarcoma oncogene cellular homolog (p-FAK/p-Src) cascade and its downstream molecules were assessed. RESULTS The in-vitro study confirmed the synergistic effect of rosuvastatin with dasatinib, which entailed the in-vivo results. The two drugs decreased the p-FAK/p-Src cue along with p-Ras/c-Raf, p-STAT-3, and p-Akt levels to enhance apoptosis by an increase in caspase-3 level and a decline in survivin level. Additionally, they inhibited HGF, VEGF, and the MMP-9. Moreover, the different treatments downregulated the expression of proliferative cell nuclear antigen (PCNA) and Ki-67. The best effect was mediated by the combination regimen that surpassed the effect of either drug alone. CONCLUSION Our results highlighted some of the signals involved in rosuvastatin antitumor effect and nominate it as an adds-on therapy with dasatinib to yield a better effect in HCC through inhibiting the FAK/Src cascade.
