Statins As Anti-Hypertensive Therapy: A Systematic Review and Meta-Analysis.

Hypertension is the most prevalent condition in clinical practice. Hypertension, diabetes, and hypercholesterolaemia are major contributing factors to cardiovascular diseases. They commonly coexist in a single patient. Statins have been used as prominent medicines for the reduction of cardiovascular events. Statins have been shown to reduce blood pressure in patients with hypertension and have lipid-lowering properties in recent articles. Statins reduce blood pressure because of their impact on endothelial function, their interactions with the renin-angiotensin system, and their influence on major artery compliance. This meta-analysis aimed to ascertain the effectiveness and efficacy of statins for managing hypertension in patients with hypertension. Systematic searches were conducted on PubMed, Science Direct, Embase, Cochrane Library, and Google Scholar. Randomized controlled trials, systematic trials, and cohort studies were retrieved using keywords on statins and their use in patients with hypertension. Exclusion criteria included studies that were not in the English language, studies that did not include patients on statins with hypertension, studies that did not provide enough information, technical reports, opinions, or editorials, and studies involving patients < 18 years old. The inclusion criteria were randomized controlled trials, meta-analyses, adult patients aged > 18 years old, and studies that were freely available or through institutional login. This meta-analysis scrutinized 9361 randomized controlled trials, clinical trials, meta-analyses, and systematic reviews, of which 32 articles including 25 randomized controlled trials and seven meta-analyses were included in the final analysis. This meta-analysis of the role of statins in hypertensive patients aimed to determine the outcome of hypertension control along with antihypertensive medication. Our study showed that statins are useful in reducing both systolic and diastolic blood pressure. We used a heterogeneous model for analysis due to variations in the study characteristics. The I2 value was 0.33 (0.76, 0.10) for systolic blood pressure and 0/88 (0.86, 0.90) for diastolic blood pressure. The I2 value for the seven meta-analyses included in the study was 1.79 (2.88, 0.69).

Remission induced by renal protective therapy in nephrotic syndrome with thin basement membrane in an older patient: a case report.

BACKGROUND: Adult nephrotic syndrome is a well-known kidney disease that causes heavy proteinuria, hypoalbuminemia, hypercholesterolemia, edema, and hypertension. The treatment varies according to its underlying cause but often faces medication resistance or adverse drug effects. CASE PRESENTATION: A Japanese woman in her 80s presented with nephrotic syndrome after a 3 year latent period of urinary protein and occult blood. She did not have any secondary causes of nephrotic syndrome. Renal biopsy revealed thin glomerular basement membrane, partial foot process fusion on electron microscopy with minor glomerular change on light microscopy, and slight coarse immunoglobulin M deposition in the mesangium on immunofluorescence microscopy, which was inconsistent with any other glomerular diseases. Without steroid treatment, she dramatically remitted from proteinuria after the administration of the renal protective agents enalapril, ezetimibe, rosuvastatin, and dapagliflozin. Recurrence after 8 months of follow-up subsided with the administration of additional doses of the agents. CONCLUSIONS: This case illustrated the novel outcomes of combining medical treatment without steroid use for nephrotic syndrome with thin glomerular basement membrane disease. At the time of writing this report, the patient's renal function was stable and she was free of edema, although moderate proteinuria and occult hematuria persisted. The final diagnosis was uncertain because of the lack of genetic investigation; however, the response to the aforementioned medical treatment suggests the effectiveness of the supportive therapy.

Efficacy of single high-dose statin prior to percutaneous coronary intervention in acute coronary syndrome: a systematic review and meta-analysis.

BACKGROUND: The impacts of single high-dose statin preloading in patients undergoing percutaneous coronary intervention (PCI) have not been fully examined. This study aims to evaluate post-procedure impacts of single high-dose statin pretreatment with acute coronary syndrome (ACS). METHODS: The meta-analysis reviewed Cochrane, PubMed, and Medline databases for studies comparing single high-dose atorvastatin or rosuvastatin to placebo in ACS patients undergoing PCI. The primary endpoints included major adverse cardiovascular events (MACE), myocardial infarction (MI), all-cause mortality, and target vessel revascularization (TVR) at three months. Secondary endpoints examined were the TIMI flow grade 3 and left ventricular ejection fraction (LVEF). RESULTS: Comprehensive analysis was conducted on fifteen RCTs, encompassing a total of 6,207 patients (3090 vs 3117 patients). The pooled results demonstrated that a single high-dose of statin administered prior to PCI led to a significant decrease in the incidence of MACE at three months post-PCI compared to the control group (OR 0.50, 95%CI 0.35-0.71, p = 0.0001). The occurrence of MI (OR 0.57, 95%CI 0.42-0.77, p = 0.0002), all-cause mortality (OR 0.56, 95%CI 0.39-0.81, p = 0.0002), and TVR (OR 0.56, 95%CI 0.35-0.92, p = 0.02) was significantly lower in the statin single high-dose group compared to the control group. No significant effects on TIMI flow grade 3 (OR 1.20, 95%CI 0.94-1.53, p = 0.14) or left ventricular ejection fraction (OR 2.19, 95%CI - 0.97 to 5.34, p = 0.17) were observed. Subgroup analysis demonstrated reduced incidence of MACE with a single dose of 80 mg atorvastatin (OR 0.66, 95%CI 0.54-0.81, p < 0.0001) and 40 mg rosuvastatin (OR 0.19, 95%CI 0.07-0.54, p = 0.002). CONCLUSIONS: Single high-dose statin before PCI in patients with ACS significantly reduces MACE, MI, all-cause mortality, and TVR three months post-PCI.

Rosuvastatin-Based Lipid-Lowering Therapy for the Control of LDL Cholesterol in Patients at High Vascular Risk.

Vascular diseases are the leading cause of death in Spain. Hypercholesterolemia is not only a cardiovascular risk factor, but also underlies the etiopathogenesis of atherosclerosis. Therefore, reducing LDL cholesterol (LDL-C) to the goals recommended by clinical practice guidelines, is essential to decrease the risk of vascular complications. Despite this, current LDL-C control is scarce, even in subjects with high and very high risk. This is mainly due to an insufficient intensification of lipid-lowering treatment. In this context, it is essential to prescribe the appropriate therapy, adjusted to patient's needs based on their LDL-C and their vascular risk. Rosuvastatin, alone or in combination with ezetimibe, provides intensive LDL-C reductions (up to 50-55% and 60-75%, respectively), with a low risk of side effects and in an efficient manner, in patients both without and with established atherosclerotic vascular disease.

Use of Statin and Target Low-density lipoprotein cholesterol attainment among post-ST elevation myocardial infarction patients in Shahid Gangalal National Heart Centre, Kathmandu, Nepal.

BACKGROUND: and objective: Lipid-lowering is an important intervention to reduce cardiovascular morbidity and mortality in the secondary prevention of STEMI. There is no study to analyze the use of statin and LDL-C treatment target attainment among STEMI patients in Nepal. This study aims to assess the use of statin and LDL-C treatment target attainment among STEMI patients. METHODS: It was a prospective observational single-center study conducted at the Shahid Gangalal National Heart Centre, Kathmandu, Nepal outpatient department. An outpatient department-based survey was conducted among STEMI patients who have lipid profile levels at the time of admission for STEMI and after 4-13 weeks of the index event. Lipid profile levels, diagnosis, and risk factors were collected during the outpatient follow-up. RESULTS: Our study included 280 post-STEMI patients; the mean age was 57.5±11.7 years with the majority being male. The mean duration of follow-up was 6.7 ± 0.1 weeks. Rosuvastatin was the preferred statin with 82.1%. The most common dose of statin used was Rosuvastatin 20mg (70%), followed by Atorvastatin 40mg (12.5%). LDL-C levels of <1.4mmol/l were achieved in 44.6% of cases and LDL levels of <1.8mmol/l in 71.8% of cases. In 36.8% of the study population, there was a greater than 50% decline in LDL-C levels. Diabetic patients (55.1% and 83.1%) only have the significant achievement of LDL goal of both <1.4mmol/l and <1.8mmol/l respectively, when compared to those without diabetes (44.9% and 16.9%). CONCLUSIONS: Most of the post-STEMI patients were treated with high doses of statins and achieved the target LDL-C levels.

Efficacy and safety of topical rosuvastatin & melatonin vs. placebo in patients with mild to moderate plaque psoriasis: A preliminary randomized double-blinded clinical trial.

BACKGROUND: Considering the pathogenesis of psoriasis and also the anti-oxidant, immunomodulatory, and anti-inflammatory properties of rosuvastatin and melatonin, the current clinical trial aimed to evaluate the efficacy of topical rosuvastatin and melatonin in patients with mild to moderate psoriasis. METHODS: The current randomized placebo-controlled clinical trial was conducted using a 3-arm parallel group included 77 adult patients (≥18 years old) with mild to moderate plaque psoriasis. Patients were randomized into a 1:1:1 ratio to one of three groups to receive one of the three interventions: melatonin cream, 5.0% (w/w), rosuvastatin cream, 5.0% (w/w), or placebo cream with a similar transparent appearance twice a day for 12 weeks. The primary outcome was severity of the disease using Psoriasis Area Severity Index (PASI). The secondary outcomes included the Dermatological Sum Score (DSS) to assess the erythema, scaling, and plaque elevation and the Dermatology Life Quality Index (DLQI). Photographs of the lesions were also taken at the baseline and at different periodic intervals thereafter. RESULTS: Among 77 randomized patients, 52 (mean (SD) age, 40.67 (10.85) years; 22 (42.30%) men) completed the study. A significant reduction of 45% (mean (SD) of 2.67 (0.98) to 1.74 (1.12)) and 70% (mean (SD) of 2.67 (0.98) to 1.31 (1.13)) in PASI score, and 46% (mean (SD) of 2.91(1.85) to 1.57 (1.11)) and 77% (mean (SD) of 2.91 (1.85) to 0.87 (0.67)) in DSS score on days 30 and 60 with rosuvastatin cream, 5% w/w (P < 0.001) compared with baseline was observed, respectively. Also a significant decrease of 35% (mean (SD) of 2.67 (0.98) to 1.74 (1.12)) and 51% (mean (SD) of 2.67 (0.98) to 1.31 (1.13)) in PASI score, and 40% (mean (SD) of 5.00 (1.58) to 3.00 (1.76))and 61% (mean (SD) of 5.00 (1.58) to 1.92 (1.71)) in DSS score on days 30 and 60 with melatonin cream, 5% w/w (P < 0.001) compared with baseline were observed, respectively. In each of the melatonin or rosuvastatin groups, DLQI improved significantly on days 30 (P < 0.0001) and 60 (P < 0.001) while the changes in the control group were not significant. CONCLUSION: The results of this clinical trial demonstrated that topical melatonin and rosuvastatin diminished the severity of mild to moderate plaque psoriasis with a satisfactory safety profile. Future clinical trials should assess both the long-term efficacy and safety of melatonin and rosuvastatin creams in larger study populations.

Development of a highly sensitive and green first-derivative synchronous fluorescence spectroscopic method for the simultaneous quantification of telmisartan and rosuvastatin: Greenness metric assessment and application to a pharmacokinetic study in rats.

Hypertension and hyperlipidemia frequently coexist and are correlated with elevated cardiovascular adverse outcomes. Fixed dose combination tablets containing antihypertensive and antihyperlipidemic drugs have the potential to improve patient compliance. Telmisartan and rosuvastatin fixed dose combination tablet has been recently formulated. This study provided the first fluorescence spectroscopic method for simultaneously quantifying telmisartan and rosuvastatin in tablet dosage form and plasma. The native fluorescence spectra of telmisartan and rosuvastatin completely overlapped, making direct measurement unachievable. However, through the implementation of synchronous fluorescence measurements of telmisartan and rosuvastatin at a Δλ = 60, distinct narrow bands were observed at 358 nm and 375 nm, respectively. Regrettably, the challenge of overlapping remained unresolved. Nevertheless, by converting these synchronous spectra into first-order spectra, the problem of overlapping was completely resolved. This conversion also allowed for the selective quantification of telmisartan and rosuvastatin at 374 nm and 358 nm, respectively. The validity of this method was confirmed in accordance with ICH guidelines, yielding satisfactory results in terms of the validation characteristics. The method demonstrated linear relationships between the response and the studied drugs concentrations in working range of 50-1000 ng/mL for telmisartan and 100-2000 ng/mL for rosuvastatin. The described methodology was applied for the pharmacokinetic study of telmisartan and rosuvastatin in rat plasma after a single oral dose of 4 mg/kg telmisartan and 50 mg/kg rosuvastatin. Pharmacokinetic analyses revealed a moderate drug-drug interaction between the two drugs, which was not considered to be clinically significant. Moreover, the described method was assessed in terms of sensitivity and environmental sustainability against three previously documented methods. The comparison effectively underscores the supremacy of the proposed technique over the documented techniques.

Magnesium-oxide-enhanced bone regeneration: 3D-printing of gelatin-coated composite scaffolds with sustained Rosuvastatin release.

Critical-size bone defects are one of the main challenges in bone tissue regeneration that determines the need to use angiogenic and osteogenic agents. Rosuvastatin (RSV) is a class of cholesterol-lowering drugs with osteogenic potential. Magnesium oxide (MgO) is an angiogenesis component affecting apatite formation. This study aims to evaluate 3D-printed Polycaprolactone/ß-tricalcium phosphate/nano-hydroxyapatite/ MgO (PCL/ß-TCP/nHA/MgO) scaffolds as a carrier for MgO and RSV in bone regeneration. For this purpose, PCL/ß-TCP/nHA/MgO scaffolds were fabricated with a 3D-printing method and coated with gelatin and RSV. The biocompatibility and osteogenicity of scaffolds were examined with MTT, ALP, and Alizarin red staining. Finally, the scaffolds were implanted in a bone defect of rat's calvaria, and tissue regeneration was investigated after 3 months. Our results showed that the simultaneous presence of RSV and MgO improved biocompatibility, wettability, degradation rate, and ALP activity but decreased mechanical strength. PCL/ß-TCP/nHA/MgO/gelatin-RSV scaffolds produced sustained release of MgO and RSV within 30 days. CT images showed that PCL/ß-TCP/nHA/MgO/gelatin-RSV scaffolds filled approximately 86.83 + 4.9 % of the defects within 3 months and improved angiogenesis, woven bone, and osteogenic genes expression. These results indicate the potential of PCL/ß-TCP/nHA/MgO/gelatin-RSV scaffolds as a promising tool for bone regeneration and clinical trials.

Comparative effects of pravastatin and rosuvastatin on carbohydrate metabolism in an experimental diabetic rat model.

Statin treatment may increase the risk of diabetes; there is insufficient data on how statins affect glucose regulation and glycemic control and the effects of statins on liver enzymes related to carbohydrate metabolism have not been fully studied. Therefore, we aimed to compare the effects of the statin derivatives, pravastatin, and rosuvastatin, on carbohydrate metabolism in an experimental diabetic rat model. Female Wistar albino rats were used and diabetes was induced by intraperitoneal injection of streptozotocin. Thereafter, 10 and 20 mg kg-1 day-1 doses of both pravastatin and rosuvastatin were administered by oral gavage to the diabetic rats for 8 weeks. At the end of the experiment, body masses, the levels of fasting blood glucose, serum insulin, insulin resistance (HOMA-IR), liver glycogen, and liver enzymes related to carbohydrate metabolism were measured. Both doses of pravastatin significantly in creased the body mass in diabetic rats, however, rosuvastatin, especially at the dose of 20 mg kg-1 day-1 reduced the body mass signi ficantly. Pravastatin, especially at a dose of 20 mg kg-1 day-1, caused significant increases in liver glycogen synthase and glucose 6-phosphate dehydrogenase levels but significant decreases in the levels of glycogen phosphorylase, lactate dehydrogenase, and glucose-6-phosphatase. Hence, pravastatin partially ameliorated the adverse changes in liver enzymes caused by diabetes and, especially at the dose of 20 mg kg-1 day-1, reduced the fasting blood glucose level and increased the liver glycogen content. However, rosuvastatin, especially at the dose of 20 mg kg-1 day-1, significantly reduced the liver glycogen synthase and pyruvate kinase levels, but increased the glycogen phosphorylase level in diabetic rats. Rosuvastatin, 20 mg kg-1 day-1 dose, caused significant decreases in the body mass and the liver glycogen content of diabetic rats. It can be concluded that pravastatin, especially at the dose of 20 mg kg-1 day-1 is more effective in ameliorating the negative effects of diabetes by modulating carbohydrate metabolism.

Clinical Analysis and in Vitro Correlation of BCRP-Mediated Drug-Drug Interaction in the Gastrointestinal Tract.

Breast cancer resistance protein (BCRP) is a drug efflux transporter expressed on the epithelial cells of the small intestine and on the lateral membrane of the bile duct in the liver; and is involved in the efflux of substrate drugs into the gastrointestinal lumen and secretion into bile. Recently, the area under the plasma concentration-time curve (AUC) of rosuvastatin (ROS), a BCRP substrate drug, has been reported to be increased by BCRP inhibitors, and BCRP-mediated drug-drug interaction (DDI) has attracted attention. In this study, we performed a ROS uptake study using human colon cancer-derived Caco-2 cells and confirmed that BCRP inhibitors significantly increased the intracellular accumulation of ROS. The correlation between the cell to medium (C/M) ratio of ROS obtained by the in vitro study and the absorption rate constant (ka) ratio obtained by clinical analysis was examined, and a significant positive correlation was observed. Therefore, it is suggested that the in vitro study using Caco-2 cells could be used to quantitatively estimate BCRP-mediated DDI with ROS in the gastrointestinal tract.

The effect of rosuvastatin alone or in combination with fenofibrate or omega-3 fatty acids on lipoprotein(a) levels in patients with mixed hyperlipidemia.

Introduction: Lipoprotein(a) [Lp(a)] is a strong, genetically determined, pathogenetic factor of atherosclerotic cardiovascular disease (ASCVD). The aim of this post-hoc analysis was to compare the effect of hypolipidemic treatment on Lp(a) levels of patients with mixed hyperlipidemia. Material and methods: We previously randomized patients with mixed hyperlipidemia (low-density lipoprotein [LDL-C] > 160 mg/dl and triglycerides > 200 mg/dl) to rosuvastatin monotherapy 40 mg/day (R group, n = 30) or rosuvastatin 10 mg/day combined with fenofibrate 200 mg/day (RF group, n = 30) or omega-3 fatty acids 2 g/day (RΩ group, n = 30). In the present post-hoc analysis, we included only the patients whose Lp(a) levels were assessed (16, 16 and 15 in the R, RF and RΩ groups, respectively). Lipid profile and Lp(a) were measured at baseline and after 3 months of treatment. Results: Significant reductions in total cholesterol, LDL-C, non-high-density lipoprotein-cholesterol (non-HDL-C) and triglyceride levels were observed in all groups. A significant increase in Lp(a) levels was noted in the R (p = 0.017) and RF (p = 0.029) groups, while no significant difference was seen in the RΩ group (p = NS). Regarding Lp(a) elevations, no differences were found between groups. In the R group, a strong negative correlation between the changes in Lp(a) and LDL-C (r = -0.500, p = 0.049) was observed, while a significant negative correlation between the changes in Lp(a) and triglycerides (r = -0.531, p = 0.034) was noted in the RF group. Conclusions: Rosuvastatin and/or fenofibrate treatment increases Lp(a) levels in patients with mixed hyperlipidemia. Novel therapies should target Lp(a) level reduction to decrease the residual ASCVD risk in patients with mixed hyperlipidemia.

Pharmacokinetic and Safety Comparison of Fixed-Dose Combination of Cilostazol/Rosuvastatin (200 + 20 mg) Versus Concurrent Administration of the Separate Components in Healthy Adults.

The combined cilostazol and rosuvastatin therapy is frequently used for coronary artery disease treatment. This open-label, 3 × 3 crossover clinical trial evaluated the pharmacokinetics and safety of a fixed-dose combination (FDC) of cilostazol/rosuvastatin (200 + 20 mg) versus a concurrent administration of the separate components (SCs) under both fasted and fed conditions. Among 48 enrolled healthy adults, 38 completed the study. Participants were administered a single oral dose of cilostazol/rosuvastatin (200 + 20 mg), either as an FDC or SCs in a fasted state, or FDC in a fed state, in each period of the trial. Blood samples were taken up to 48 hours after dosing, and plasma concentrations were analyzed using validated liquid chromatography-tandem mass spectrometry. The geometric mean ratios of FDC to SCs for area under the plasma concentration-time curve from time zero to the last quantifiable concentration (AUClast ) and maximum plasma concentration (Cmax ) were 0.94/1.05 and 1.06/1.15 for cilostazol and rosuvastatin, respectively (AUClast /Cmax ). Compared with that during fasting, fed-state administration increased the AUClast and Cmax for cilostazol by approximately 72% and 160% and decreased these parameters for rosuvastatin by approximately 39% and 43%, respectively. To conclude, the FDC is bioequivalent to the SCs, with notable differences in pharmacokinetics when administered in a fed state. No significant safety differences were observed between the treatments.

Efficacy and safety of combination therapy with telmisartan, rosuvastatin, and ezetimibe in patients with dyslipidemia and hypertension: A randomized, double-blind, multicenter, therapeutic confirmatory, phase III clinical trial.

This study aimed to compare and evaluate the efficacy of the blood pressure (BP) control and cholesterol-lowering effects and safety of combination therapy with telmisartan, rosuvastatin, and ezetimibe versus rosuvastatin and ezetimibe double therapy or telmisartan single therapy in dyslipidemia patients with hypertension. After a wash-out/therapeutic lifestyle change period of ≥4 weeks, a total of 100 eligible patients were randomized and received one of three treatments for 8 weeks: (1) telmisartan 80 mg/rosuvastatin 20 mg/ezetimibe 10 mg (TRE), (2) rosuvastatin 20 mg/ezetimibe 10 mg (RE), or (3) telmisartan 80 mg (T). The primary endpoint was the efficacy evaluation of TRE by comparing changes in mean sitting systolic blood pressure (msSBP) and mean percentage change in low-density lipoprotein-C (LDL-C) from baseline after 8 weeks of treatment. The least square (LS) mean (SE) changes in msSBP at 8 weeks compared with baseline were -23.02 (3.04) versus -7.18 (3.09) mmHg in the TRE and RE groups, respectively (p < .0001), and -25.80 (2.74) versus -14.92 (2.65) mmHg in the TRE and T groups, respectively (p = .0005). The percentage changes in the mean (SD) LDL-C at 8 weeks compared with baseline were -54.97% (3.49%) versus -0.17% (3.23%) in the TRE and T groups, respectively (p < .0001). No serious adverse events occurred, and no statistically significant differences in the incidence of overall AEs and adverse drug reactions occurred among the three groups. TRE therapy significantly decreased msSBP and LDL-C compared to RE or T therapy with comparable safety and tolerability profiles.

Fabrication of Rosuvastatin-Incorporated Polycaprolactone -Gelatin Scaffold for Bone Repair: A Preliminary In Vitro Study.

OBJECTIVE: Rosuvastatin (RSV) is a hydrophilic, effective statin with a long half-life that stimulates bone regeneration. The present study aims to develop a new scaffold and controlled release system for RSV with favourable properties for bone tissue engineering (BTE). MATERIALS AND METHODS: In this experimental study, high porous polycaprolactone (PCL)-gelatin scaffolds that contained different concentrations of RSV (0 mg/10 ml, 0.1 mg/10 ml, 0.5 mg/10 ml, 2.5 mg/10 ml, 12.5 mg/10 ml, and 62.5 mg/10 ml) were fabricated by the thermally-induced phase separation (TIPS) method. Mechanical and biological properties of the scaffolds were evaluated by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), compressive strength, porosity, MTT, alkaline phosphatase (ALP) activity, water contact angle, degradation rate, pH alteration, blood clotting index (BCI), and hemocompatibility. RESULTS: SEM analysis confirmed that the porous structure of the scaffolds contained interconnected pores. FTIR results showed that the RSV structure was maintained during the scaffold's fabrication. RSV (up to 62.5 mg/10 ml) increased compressive strength (16.342 ± 1.79 MPa), wettability (70.2), and degradation rate of the scaffolds. Scaffolds that contained 2.5 mg/10 ml RSV had the best effect on the human umbilical cord mesenchymal stem cell (HUC-MSCs) survival, hemocompatibility, and BCI. As a sustained release system, only 31.68 ± 0.1% of RSV was released from the PCL-Gelatin-2.5 mg/10 ml RSV scaffold over 30 days. In addition, the results of ALP activity showed that RSV increased the osteogenic differentiation potential of the scaffolds. CONCLUSION: PCL-Gelatin-2.5 mg/10 ml RSV scaffolds have favorable mechanical, physical, and osteogenic properties for bone tissue and provide a favorable release system for RSV. They can mentioned as a a promising strategy for bone regeneration that should be further assessed in animals and clinical studies.

Adverse neurobehavioral changes with reduced blood and brain cholinesterase activities in mice treated with statins.

Background and Aim: Pleiotropic effects of hypolipidemic statins with behavioral outcomes have been suggested in humans and laboratory animals. There is limited information on the neurobehavioral effects of statins in mice. The aim of the present study was to examine changes in neurobehavioral performance and cholinesterase (ChE) activity in mice after high doses of three commonly used statins (atorvastatin, simvastatin, and rosuvastatin). Materials and Methods: Two hours after vehicle (control) or statin dosing at 250, 500, 750, or 1000 mg/kg orally, each mouse was subjected to 5 min open-field activity, negative geotaxis at an angle of 45°/60 s, 5 min head pocking, and forced swimming endurance. Plasma, erythrocyte, and brain ChE activities were determined spectrophotometrically 2 and 24 h after oral dosing of statins at 500 and 1000 mg/kg. Results: The statins variably, but dose-dependently and significantly (p < 0.05) delayed the latency to move in the open-field arena, decreased locomotion and rearing, reduced head pocking, and delayed negative geotaxis performance. However, statins significantly increased the duration of forced swimming and decreased the duration of immobility in the swimming tank. Statins significantly and dose-dependently decreased plasma, erythrocyte, and brain ChE activity 2 and 24 h after dosing. Plasma and brain ChE activities recovered by 5%-32.9% and 5.7%-14.4% 24 h later from the 2 h ChE values, respectively. Conclusion: High doses of statins differentially modulate neurobehavioral outcomes in mice in association with reduced plasma, erythrocyte, and brain ChE activity. Plasma or erythrocyte ChE may be used for biomonitoring of the adverse/therapeutic effects of statins.

Rosuvastatin as a Supplemental Treatment for the Clinical Symptoms of Nephropathia Epidemica: A Pilot Clinical Study.

Nephropathis epidemica (NE), a mild form of hemorrhagic fever with renal syndrome (HFRS), is an acute zoonotic disease endemic in the Republic of Tatarstan. This study aimed to assess the impact of rosuvastatin on the clinical and laboratory results of NE. A total of 61 NE patients and 30 controls were included in this study; 22 NE patients and 7 controls received a daily dose of rosuvastatin (10 mg) for ten consecutive days. Serum samples were collected on days 1, 5, and 10 after admission to the hospital. These samples were analyzed to determine the levels of lipids, cytokines, and kidney toxicity markers. Our findings indicate that rosuvastatin reduced the duration of the second wave of fever and alleviated back pain and headache symptoms. Additionally, low-density lipoprotein cholesterol (LDL-C) serum levels were significantly decreased on days 5 and 10 upon rosuvastatin treatment. Furthermore, rosuvastatin decreased the levels of cytokines in the serum, particularly proinflammatory cytokines IL-1ß and IL-8. NE patients had significantly altered levels of the kidney toxicity markers albumin and osteopontin. The data from our study provide evidence supporting the therapeutic potential of rosuvastatin in NE cases.

Efficacy and Safety of Triple Therapy of Telmisartan/Amlodipine/Rosuvastatin in Patients with Dyslipidemia and Hypertension: A Multicenter Randomized Clinical Trial.

Background: Hypertension and dyslipidemia significantly contribute to cardiovascular disease development. Their coexistence poses challenges in managing multiple medications, influencing treatment adherence. Objective: This study aimed to assess the efficacy and safety of a combined treatment approach using a fixed-dose combination therapy. Methods: This multicenter, 8-week, randomized, double-blind, Phase IV trial was named Telmisartan/Amlodipine/Rosuvastatin from Samjin Pharmaceuticals and evaluated the efficacy and safety of fixed-dose combination treatment in patients with essential hypertension and dyslipidemia. They were randomly assigned to 2 fixed-dose combination therapy groups, telmisartan 40 mg/amlodipine 5 mg/rosuvastatin 10 mg (TEL/ALD/RSV) or amlodipine 5 mg/atorvastatin 10 mg (ALD/ATV) after washout/run-in period. The primary outcomes were the change in mean sitting systolic blood pressure and the percentage change of LDL-C after 8 weeks of medical treatment. Adverse drug reactions and events were assessed. Results: Of a total of 304 patients who underwent screening, 252 were randomized to the TEL/ALD/RSV group (125 patients) and the ALD/ATV group (127 patients). The mean (SD) ages of the TEL/ALD/RSV group and the ALD/ATV group were 67.4 (11.3) and 68.2 (10.6) years, respectively (P = 0.563). The least-squares mean (SE) in mean sitting systolic blood pressure changes between the 2 groups were -16.27 (0.93) mm Hg in the TEL/ALD/RSV group, -6.85 (0.92) mm Hg in the ALD/ATV group (LSM difference = -9.42 mm Hg; 95% CI, -11.99 to -6.84; P < .001). For LDL-C level changes, a significant difference was noted between the 2 groups: -50.03% (1.18%) in the TEL/ALD/RSV group, -39.60% (1.17%) in the ALD/ATV group (LSM difference = -10.43%; 95% CI, -13.70 to -7.16; P < .001). No severe adverse events were observed. Conclusions: TEL/ALD/RSV proved to be more efficient than ALD/ATV in lowering blood pressure and reducing LDL-C levels among patients with hypertension and dyslipidemia, with no notable safety concerns.

Prevention of neointimal hyperplasia after coronary artery bypass graft via local delivery of sirolimus and rosuvastatin: network pharmacology and in vivo validation.

BACKGROUND: Coronary artery bypass graft (CABG) is generally used to treat complex coronary artery disease. Treatment success is affected by neointimal hyperplasia (NIH) of graft and anastomotic sites. Although sirolimus and rosuvastatin individually inhibit NIH progression, the efficacy of combination treatment remains unknown. METHODS: We identified cross-targets associated with CABG, sirolimus, and rosuvastatin by using databases including DisGeNET and GeneCards. GO and KEGG pathway enrichment analyses were conducted using R studio, and target proteins were mapped in PPI networks using Metascape and Cytoscape. For in vivo validation, we established a balloon-injured rabbit model by inducing NIH and applied a localized perivascular drug delivery device containing sirolimus and rosuvastatin. The outcomes were evaluated at 1, 2, and 4 weeks post-surgery. RESULTS: We identified 115 shared targets between sirolimus and CABG among databases, 23 between rosuvastatin and CABG, and 96 among all three. TNF, AKT1, and MMP9 were identified as shared targets. Network pharmacology predicted the stages of NIH progression and the corresponding signaling pathways linked to sirolimus (acute stage, IL6/STAT3 signaling) and rosuvastatin (chronic stage, Akt/MMP9 signaling). In vivo experiments demonstrated that the combination of sirolimus and rosuvastatin significantly suppressed NIH progression. This combination treatment also markedly decreased the expression of inflammation and Akt signaling pathway-related proteins, which was consistent with the predictions from network pharmacology analysis. CONCLUSIONS: Sirolimus and rosuvastatin inhibited pro-inflammatory cytokine production during the acute stage and regulated Akt/mTOR/NF-κB/STAT3 signaling in the chronic stage of NIH progression. These potential synergistic mechanisms may optimize treatment strategies to improve long-term patency after CABG.

Oxidative Stress-Induced Adverse Effects of Three Statins Following Single or Repetitive Treatments in Mice.

Background and objective The hypolipidemic statins have been associated with various side effects, and in some cases, adverse reactions in humans and experimental animals, such as myotoxicity, neurobehavioral toxicity, as well as liver and kidney injuries. The purpose of the present study was to examine the possibility of the induction of oxidative stress in the brain and plasma of mice dosed with single or repetitive doses of three statins (atorvastatin, simvastatin, and rosuvastatin). Methods Male Swiss-origin mice were dosed orally with single doses of each of the three statins at 500 or 1000 mg/kg of body weight. Other groups of mice were dosed orally with repeated daily doses of each of the statins at 200 mg/kg of body weight/day for 14 or 28 consecutive days. These doses of statins were chosen to not produce overt toxicity in mice within the time frame allocated for each experiment. Brain and plasma glutathione (GSH) and malondialdehyde (MDA) levels, as well as liver enzymes activities alanine transaminase (ALT) and aspartate transaminase (AST), were determined using commercial kits. Results Single-dose treatments of the mice with the statins at either 500 or 1000 mg/kg significantly and dose-dependently (p < 0.05) reduced the GSH level in the plasma and the whole brain when compared with respective control values. Atorvastatin was the least effective statin, as only the high dose achieved a significant reduction in brain GSH level in comparison with the respective control value. Repetitive administration of the three statins at 200 mg/kg of body weight/day for 14 or 28 consecutive days significantly and time-dependently reduced plasma and brain GSH levels in comparison with respective control values. The oxidative stress biomarker MDA level significantly increased in the plasma and brain of mice following single or repetitive treatments with the three statins, and the most effective one was rosuvastatin. In association with these changes, activities of the liver enzymes ALT and AST were also increased in the plasma with single and repetitive statin treatments, and the most effective one was rosuvastatin. Conclusion The data suggest an association of high doses of three statins (atorvastatin, simvastatin, and rosuvastatin) with the induction of oxidative stress manifested as GSH reduction and MDA elevation as adverse effects in the brain and plasma of mice, which suffered from the additional burden of liver injury. These effects could be the basis of an in-depth exploration of statin adverse effects in experimental animals and to find an animal model, probably the mice, for the induction of adverse effects of statins that target the brain, as well as to shed light on potential statin intolerance outcomes following single-dose treatments in this species.
