Efficacy of topical atorvastatin-loaded emulgel and nano-emulgel 1% on post-laparotomy pain and wound healing: A randomized double-blind placebo-controlled clinical trial.
This study aimed to develop atorvastatin-loaded emulgel and nano-emulgel dosage forms and investigate their efficiency on surgical wound healing and reducing post-operative pain. This double-blind randomized clinical trial was conducted in a surgical ward of a tertiary care hospital affiliated with university of medical sciences. The eligible patients were adults aged 18 years or older who were undergoing laparotomy. The participants were randomized in a 1:1:1 ratio to one of three following groups of atorvastatin-loaded emulgel 1% (n = 20), atorvastatin-loaded nano-emulgel 1% (n = 20), and placebo emulgel (n = 20) twice a day for 14 days. The primary outcome was the Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA) scores to determine the rate of wound healing. The Visual Analogue Scale (VAS) and quality of life were the secondary outcomes of this study. A total of 241 patients assessed for eligibility; of them, 60 patients completed the study and considered for final evaluation. A significant decrease in REEDA score was observed on Days 7 (63%) and 14 (93%) of treatment with atorvastatin nano-emulgel (p-value < 0.001). A significant decrease of 57% and 89% in REEDA score was reported at Days 7 and 14, respectively, in atorvastatin the emulgel group (p-value < 0.001). Reduction in pain VAS in the atorvastatin nano-emulgel was also recorded at Days 7 and 14 of the intervention. The results of the present study suggested that both topical atorvastatin-loaded emulgel and nano-emulgel 1% were effective in acceleration of wound healing and alleviation of pain of laparotomy surgical wounds, without causing intolerable side effects.

PURPOSE
Our purpose was to verify the effects of atorvastatin (ATO) on prostate cancer (PCa) proliferation, apoptosis, invasion, and metastasis and to further explore the drug's mechanism of action.
MATERIALS AND METHODS
We used cell counting kit-8 (CCK8) and clone formation experiments to study the effect of ATO on the proliferation of PC3 cells. Flow cytometry and Hoechst 33342 staining were used to detect cell apoptosis. Cell migration and invasion were detected through wound healing experiments and transwell experiments. Western blotting was applied to detect apoptosis-related proteins (BAX, Bcl-2, PARP, and Caspase-3), epithelial-mesenchymal transformation (EMT) proteins, and matrix metalloproteinase (MMP) expression. A mouse xenograft tumor model was established, and tumor volume and weight were determined. The expression levels of the above-mentioned proteins were determined through western blot.
RESULTS
ATO inhibited PC-3 cell proliferation and promoted cell apoptosis in a dose-dependent manner. ATO significantly up-regulated the expression of BAX, PARP, and Caspase-3 and inhibited the expression of Bcl-2. Wound healing and transwell experiments showed that ATO inhibited invasion and metastasis in PC-3 cells, possibly because ATO could inhibit the EMT and the expression of MMPs in PC-3 cells. Studies in nude mice showed that ATO significantly reduced tumor volume and weight; the expression levels of related proteins were consistent with the results.
CONCLUSIONS
ATO inhibits the occurrence and development of PCa and regulates the migration and invasion of PCa cells by inhibiting the EMT and MMPs.

Randomized Controlled Trial
BACKGROUND
Atorvastatin decreases blood lipids but is associated with side effects. Zhibitai is a traditional Chinese medicine used to treat blood lipid disorders. The objective of this study is to evaluate the lipid-lowering effect, antiinflammatory effect, and adverse events of zhibitai combined to atorvastatin in patients with coronary heart diseases (CHDs).
METHODS
Patients with CHD (n = 150) were randomized to: zhibitai 480 mg + atorvastatin 10 mg (ZA10 group), atorvastatin 20 mg (A20 group), and atorvastatin 40 mg (A40 group). Lipid profile, cardiotrophin-1 (CT-1), and C-reactive protein (CRP) were measured after 4 and 8 weeks of treatment. Self-reported side effects, liver function, kidney function, and creatine kinase levels were monitored.
RESULTS
After 8 weeks, triglycerides, total cholesterol (TC), LDL-cholesterol (LDL-C), and apolipoprotein B100 (ApoB100) levels were decreased in the ZA10 group (-64%, -37%, -46%, and -54%, respectively, compared with baseline), and these changes were similar to those of the A40 group (P > 0.05). CT-1 and high sensitivity-C reactive protein (hs-CRP) levels were significantly decreased in the ZA10 group after 4 and 8 weeks (4 weeks: -73% and 96%; 8 weeks: -89% and -98%; all P < 0.01), without differences among the 3 groups (P > 0.05). After 8 weeks of treatment, adverse events (abdominal distention, nausea, vomiting, and hunger) were found in 4, 5, and 7 patients in the ZA10, A20, and A40 groups, respectively.
CONCLUSION
ZA10 significantly reduced triglycerides, TC, LDL-C, ApoB, CT-1, and hs-CRP levels in patients with CHD, similar to the effects of A40 and A20, but ZA10 lead to fewer adverse events.

Hypertension and dyslipidemia are important risk factors for cardiovascular disease. However, the clinical outcomes of fixed-dose combination (FDC) versus free-equivalent combination (FEC) of amlodipine and atorvastatin in the treatment of concurrent hypertension and dyslipidemia remain unknown. In this study, we included patients with newly diagnosed hypertension and dyslipidemia, without previously established cardiovascular disease, and treated with either FDC or FEC of amlodipine and atorvastatin were identified from the National Health Insurance Research Database of Taiwan and follow-up for 5 years. By using 1:1 propensity score matching, a total of 1756 patients were enrolled in this study. The composite of major adverse cardiovascular events, including all-cause mortality, myocardial infarction (MI), stroke, and coronary revascularization, occurred more frequently in the FEC group than in the FDC group (hazard ratio, 1.88; 95% confidence interval [CI], 1.42 to 2.5). Although the all-cause mortality did not differ (hazard ratio, 0.46; 95% CI, 0.36 to 1.59), the FEC group developed increased MI, stroke, and coronary revascularization (hazard ratio, 2.87; 95% CI, 1.07 to 7.68; hazard ratio, 1.97; 95% CI, 1.41 to 2.74; and hazard ratio, 2.44; 95% CI, 1.26 to 4.69, respectively). Furthermore, as an unexpected result, a higher risk to develop new-onset diabetes mellitus was observed with FEC regimens (hazard ratio, 2.19; 95% CI, 1.6 to 3.0). In conclusion, although the all-cause mortality did not differ between the two groups, the FDC regimen of amlodipine and atorvastatin improved clinical outcomes when compared to FEC in patients with newly diagnosed hypertension and dyslipidemia.

Randomized Controlled Trial
AIM
The PLANET trials showed that atorvastatin 80 mg but not rosuvastatin at either 10 or 40 mg reduced urinary protein to creatinine ratio (UPCR) at similar effects on LDL-cholesterol. However, individual changes in both UPCR and LDL-cholesterol during treatment with these statins varied widely between patients. This inter-individual variability could not be explained by patients' physical or biochemical characteristics. We assessed whether the plasma concentrations of both statins were associated with LDL-cholesterol and UPCR response.
MATERIALS AND METHODS
The PLANET trials randomized patients with a UPCR of 500-5000 mg/g and fasting LDL-cholesterol >2.33 mmol/L to a 52-week treatment with atorvastatin 80 mg, rosuvastatin 10 mg or 40 mg. For the current analysis, patients with available samples at week 52 and treatment compliance >80% by pill count were included (N = 295). The main outcome measurements were percentage change in UPCR and absolute change in LDL-cholesterol (delta LDL) from baseline to week 52.
RESULTS
Median (interquartile range) plasma concentration at week 52 for atorvastatin 80 mg was 3.9 ng/mL (IQR: 2.1 to 8.7), for rosuvastatin 10 mg 1.0 ng/mL (IQR: 0.7 to 2.0) and for rosuvastatin 40 mg 3.5 ng/mL (IQR: 2.0 to 6.8). Higher plasma concentration of statin was associated with larger LDL-cholesterol reductions at week 52 [rosuvastatin r = -0.40 (P < .001); atorvastatin r = -0.28 (P = .006)]. The plasma concentration of both statins did not correlate with UPCR change [rosuvastatin r = 0.07 (P = .30); atorvastatin r = 0.16 (P = .13)].
CONCLUSIONS
Individual variation in plasma concentrations of rosuvastatin and atorvastatin was associated with LDL-cholesterol changes in patients. The individual variation in UPCR change was not associated with the plasma concentration of both statins.

INTRODUCTION
Hypoprolactinemia, which is usually a consequence of treatment with inadequate high doses of dopaminergic agents, is a poorly understood clinical condition. The aim of the current study was to investigate whether the cardiometabolic effects of statin therapy differ between patients with low prolactin production and patients with normal levels of this hormone.
METHODS
We studied two groups of cabergoline-treated premenopausal women with hypercholesterolemia matched for age, plasma lipids, cabergoline dose, and treatment duration: 11 women with hypoprolactinemia (group A) and 15 women with plasma levels of this hormone within the reference range (group B). The control group (C) included 25 dopaminergic-naïve normoprolactinemic women, matched for age and lipid levels. Plasma lipids, insulin sensitivity, and levels of uric acid, high-sensitivity C-reactive protein (hsCRP), fibrinogen, homocysteine, and 25-hydroxyvitamin D were measured before and after 14-week treatment with atorvastatin (20 mg daily).
RESULTS
Patients with hypoprolactinemia were more insulin-resistant, had lower values of total testosterone and free androgen index, and had higher levels of hsCRP and fibrinogen than individuals with normal prolactin levels. Although atorvastatin reduced total and LDL cholesterol and hsCRP in all study groups, this effect was stronger in groups B and C than in group A. Only in groups B and C, the drug decreased uric acid, fibrinogen, and homocysteine and increased 25-hydroxyvitamin D. In turn, only in group A, atorvastatin worsened insulin sensitivity and reduced free androgen index.
CONCLUSION
Coexisting hypoprolactinemia may have an unfavorable impact on the pleiotropic effects of statins.

Randomized Controlled Trial
Contemporary treatment of vitiligo remains a great challenge to practitioners. The vast majority of currently conducted clinical trials of modern therapeutic methods are focused on systemic medications, while there is only a very limited number of reports on new topical treatment in vitiligo. With their pleiotropic activities statins turned out to be efficient in the treatment of various autoimmune/autoinflammatory disorders. The randomized, double-blind placebo-controlled study of topical administration of the active forms of simvastatin and atorvastatin has been designed to evaluate their efficacy in patients with vitiligo. The study was registered in clinicaltrials.gov (registration number NCT03247400, date of registration: 11th August 2017). A total of 24 patients with the active form of non-segmental vitiligo were enrolled in the study. The change of absolute area of skin lesions, body surface area and vitiligo area scoring index were evaluated throughout the 12 week application of ointments containing simvastatin and atorvastatin. Measurements were performed with planimetry and processed using digital software. Use of active forms of simvastatin and atorvastatin did not result in a significant repigmentation of the skin lesions throughout the study period. Within the limbs treated with topical simvastatin, inhibition of disease progression was significantly more frequent than in the case of placebo (p = 0.004), while the difference was not statistically significant for atorvastatin (p = 0.082). Further studies of topical simvastatin in vitiligo patients should be considered.

A physiologically based pharmacokinetic model for open acid and lactone forms of atorvastatin and metabolites to assess the drug-gene interaction with SLCO1B1 polymorphisms.
Atorvastatin is the most prescribed 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor used to lower cardiovascular risk and constitutes one of the best-selling drugs world-wide. Several physiologically based pharmacokinetic (PBPK) models have been developed to assess its non-straightforward pharmacokinetics (PK) as well as that of its metabolites and have been only applied to assess drug-drug interactions (DDI). Here we present a full PBPK model for atorvastatin and its metabolites able to predict within a 2-fold error their PK after the administration of a solid oral dosage form containing the calcium salt of atorvastatin in single and multiple dosing schedules at 20, 40, and 80 mg and 10 mg dose levels, respectively. Internal validation with data from Phase 1 clinical trials as well as external validation in predicting clinically relevant DDIs consolidated model structure and parameterization. The model has been used to quantitatively assess the drug-gene interaction (DGI) between SLCO1B1 polymorphisms and atorvastatin exposure and revealed that patients with a reduced activity in hepatic uptake of atorvastatin are at increased risk of suffering muscle discomfort because of a 30% lower clearance (p < 0.01), leading to a 40% and 33% higher (p < 0.05) atorvastatin AUC and C, respectively. These findings could explain the reported hazard ratio of 1.4 (95% CI: 1.1-1.7, p = 0.02) for suffering statin-induced myopathies and the treatment discontinuation among these patients (odds ratio 1.67, p = 0.0001) observed in the context of routine clinical care.

OBJECTIVE
To investigate the effects of atorvastatin calcium on pulmonary vascular remodeling, the authors explored the regulatory mechanism of Histone Deacetylation Enzyme-2 (HDAC2) in rats with Chronic Obstructive Pulmonary Disease (COPD), and provided a new direction for drug treatment in the progression of vascular remodeling.
METHODS
Eighteen female SD rats were randomly divided into control (Group S1), COPD (Group S2), and atorvastatin calcium + COPD (Group S3) groups. A COPD rat model was established by passive smoking and intratracheal injection of Lipopolysaccharide (LPS). Haematoxylin and eosin staining and Victoria Blue + Van Gibson staining were used to observe pathological changes in the lung tissue. The pulmonary vascular inflammation score was calculated, and the degree of pulmonary vascular remodeling was evaluated. The ratio of Muscular Arteries in lung tissue (MA%), the ratio of the vessel Wall Area to the vessel total area (WA%), and the ratio of the vessel Wall Thickness to the vascular outer diameter (WT%) were measured using imaging software. The expression of HDAC2 was measured using western blotting, ELISA (Enzyme-Linked Immunosorbent Assay), and qPCR (Real-time PCR).
RESULTS
Compared with the control group, the degree of pulmonary vascular inflammation and pulmonary vascular remodeling increased in rats with COPD. The WT%, WA%, and lung inflammation scores increased significantly; the expression of HDAC2 and HDAC2mRNA in the serum and lung tissue decreased, and the level of Vascular Endothelial Growth Factor (VEGF) in the lung tissues increased (p < 0.05). Compared with the COPD group, the lung tissues from rats in the atorvastatin group had fewer inflammatory cells, and the vascular pathological changes were significantly relieved. The WT%, WA%, and lung inflammation scores decreased significantly; the expression of HDAC2 and HDAC2mRNA in the serum and lung tissues increased, and the level of VEGF in the lung tissues decreased (p < 0.05).
CONCLUSION
The present study revealed that atorvastatin calcium could regulate the contents and expression of HDAC2 in serum and lung tissues and inhibit the production of VEGF, thereby regulating pulmonary vascular remodeling in a rat model with COPD.

Randomized Controlled Trial
INTRODUCTION
Cardiovascular disease (CVD) has become a leading cause of morbidity and mortality among people with HIV. Atorvastatin is known to reduce cardiovascular risk. We (1) compared atorvastatin concentrations between different boosted protease inhibitors (PIs) and with lipid outcomes and (2) compared pre-atorvastatin 25-OH vitamin D levels with atorvastatin concentrations and with lipid outcomes, in people with HIV with suppressed HIV-1 RNA and low-density lipoprotein cholesterol (LDL-C) <130 mg/dL.
METHODS
A5275 was a randomized, double-blind, placebo-controlled crossover study of atorvastatin in virally suppressed people with HIV with fasting LDL-C <130 mg/dL. We analyzed results over the 20 weeks of active atorvastatin treatment. Atorvastatin was initiated at 10 mg daily and increased to 20 mg daily after 4 weeks if there were no findings of toxicity. Atorvastatin trough concentrations were measured at week 20. Participants took combination antiretroviral therapy (ART) that included a boosted PI throughout.
RESULTS
Overall (n = 67), 70% of participants were male, and the median age was 51 years. There was no apparent association between atorvastatin trough concentrations and pre-atorvastatin vitamin D levels (r = 0.01, p = 0.9) or by boosted PI (p = 0.20). Median pre- to post-atorvastatin change was -39.0 mg/dL in fasting total cholesterol, -40.4 ng/mL in lipoprotein-associated phospholipase A2 (LP-PLA2), and -13.8 U/L in oxidized LDL, with all changes negatively correlated with atorvastatin trough concentrations (r = -0.19, -0.09, -0.21; p ≥ 0.096).
CONCLUSIONS
No apparent associations between pre-atorvastatin vitamin D levels and outcomes were observed (all p > 0.70). In virologically suppressed people with HIV, higher atorvastatin concentrations were marginally associated with greater decreases in lipid outcomes.
