Statins are commonly used in the treatment of hyperlipidaemia. Although the benefits of statins are well-documented, they have the potential to cause myopathy and rhabdomyolysis due to the complex interactions of drugs, comorbidities and genetics. The cytochrome P450 family consists of major enzymes involved in drug metabolism and bioactivation. This article aims to highlight drug interactions involving statins, as well as provide updated recommendations and approaches regarding the safe and appropriate use of statins in the primary care setting.

Hyperlipidemia is a major factor causing coronary heart disease and atherosclerosis. The high-density lipoprotein cholesterol (HDL-C) is a major indicator for measuring lipid levels. However, there is no an effective medicine that can obviously increase HDL-C at present. According to previous laboratory studies, atractylodes macrocephalae extracts could significantly increase HDL-C level. In this study, the metabolic hyperlipidemia rat model was established by feeding high-sugar and fat diets and alcohol-drinking to explore the effect and mechanism of atractylodes macrocephalae extracts on hyperlipidemia rats. According to the findingins, different doses of atractylodes macrocephalae extracts could reduce the levels of TC, TG, LDL-C, ACAT and increase the contents of LCAT, HDL-C. Particularly, the atractylodes macrocephalae extracts (100 mg · kg(-1) group showed increase in HDL-C by about 50% and significant declines in HMG-CoA reductase, TC, TG. In conclusion, Atractylodes Macrocephelae Rhizoma extracts could effectively regulate the dyslipidemia of hyperlipidemia rats, especially on HDL-C. Its mechanism may be related to reduction in cholesterol synthesis by inhibiting HMG-CoA reductase in livers and increase in lipid metabolism and transport by regulating LCAT and ACAT levels.

BACKGROUND/AIMS: The efficacy and safety of a combination of ezetimibe and low-dose statin as primary treatment for dyslipidemia in renal transplant patients were evaluated prospectively. METHODS: The study enrolled 77 renal transplant recipients with dyslipidemia. They were given ezetimibe (10 mg) and simvastatin (10 mg) for 6 months as the initial treatment for dyslipidemia. Efficacy and safety were evaluated using lipid profiles, trough calcineurin inhibitor levels, allograft function, and adverse effects. The effects on proteinuria and high sensitivity C-reactive protein (hsCRP) levels were also evaluated. RESULTS: Ezetimibe and low-dose simvastatin significantly decreased the levels of total cholesterol (34.6%), triglyceride (16.0%), and low-density lipoprotein cholesterol (LDL-C) (47.6%), and 82.5% of the patients reached the target LDL-C level of <100 mg/dL. No significant change in the trough calcineurin inhibitor levels or allograft function occurred, and no serious adverse effects were observed. Fourteen patients (18.2%) discontinued treatment; eight patients (11.7%) developed muscle pain or weakness without an increase in creatinine kinase levels, and two patients (2.6%) developed elevated liver transaminase levels. The proteinuria and hsCRP levels did not change significantly. CONCLUSIONS: Ezetimibe and low-dose statin treatment is safe and effective as a primary treatment for dyslipidemia in renal transplant patients.

OBJECTIVEThe aim of this review is to objectively access the trial evidence on the role of omega-3, red yeast rice and garlic in preventing clinical cardiovascular events. Given the large number of clinical trials favoring statin use in cardiovascular disease, it is important to see if evidence is available for these supplements and whether they could replace statin therapy.
DATA SOURCEA PubMed search was conducted using the keywords 'trial, omega-3, red yeast rice, xuezhikang, garlic, cholesterol, cardiovascular, outcomes'; the resulting trials were reviewed together with the references quoted in the papers obtained.
STUDY SELECTIONThe studies selected are prospective, randomized, placebo-controlled studies with predefined clinical cardiovascular end-points recruiting at least 2000 patients, with a follow-up over 2 years.
RESULTSModest dose omega-3 fatty acid has been shown in GISSI-P (11 324 patients, follow-up 3.5 years) to produce a reduction in sudden death of 45%, and in cardiac death of 35%, acting probably via an anti-arrhythmic effect. In JELIS (18 645 patients, follow-up 4.6 years), high dose omega-3 given to Japanese patients on a high fish diet and already on statin treatment produced further benefit with a 19% reduction of nonfatal cardiovascular outcomes; fatal cardiac events are not affected. CCSPS (4870 patients, follow-up 4 years), a secondary prevention trial using xuezhikang, a commercial red yeast rice preparation, produced a 46% reduction in nonfatal myocardial infarction and coronary death. There has been no trial to show that garlic reduces clinical cardiovascular outcomes. A rigorous trial with constant assessment of chemicals in the study material in 192 patients found that over a 6-month follow-up, raw garlic and 2 commercial preparations do not significantly affect lipid levels.
CONCLUSIONSOmega-3 in modest doses reduces cardiac deaths, and in high doses reduces nonfatal cardiovascular events. Red yeast rice reduces adverse cardiac events to a similar degree as the statins. It is unlikely that garlic is useful in preventing cardiovascular disease.

BACKGROUNDThe role of alprostadil and statins in contrast-induced acute kidney injury (CI-AKI) is controversial. The purpose of this study was to explore the efficacy of combined therapy with alprostadil and statins in protecting renal function and preventing contrast-induced nephropathy (CIN) in patients undergoing coronary angiography.
METHODSA total of 156 consecutive patients with mild to moderate renal failure who underwent coronary angiography were enrolled in our study, and randomly categorized into two groups. In the statins group, 80 patients were treated with statins before and after coronary angiography. In the alprostadil plus statins group, 76 patients were treated with statins and alprostadil before and after coronary angiography. Serum creatinine (SCr), serum cystatin (CysC) and neutrophil gelatinase-associated lipocalin (NGAL) were detected after administration of contrast media, and adverse events were evaluated within six months.
RESULTSIn both groups, the SCr, CysC and NGAL significantly increased after coronary angiography and peaked at 48, 24 and 6 hours, respectively. SCr, CysC and NGAL were significantly lower in the alprostadil plus statins group than in the statins group (P < 0.05). The incidence of CIN in the alprostadil plus statins group was slightly lower than in the statins group. The incidence of adverse events within six months in the alprostadil plus statins group was significantly lower than in the statins group (P = 0.034).
CONCLUSIONSIntravenous alprostadil in combination with oral statins is superior to statins alone for protecting renal function in patients with mild to moderate renal dysfunction who undergo coronary angiography, and can reduce the incidence of adverse events seen within six months.

OBJECTIVETo evaluate effects of celecoxib (a selective cox-2 inhibitor)combined with fluvastatin (a HMG-CoA reductase inhibitor) on tumor growth and cell apoptosis in hepatocellular carcinoma xenograft in nude mice.
METHODSHepatocellular carcinoma BEL-7402 cells were inoculated subcutaneously into the left armpit of nude mice, the mice (n = 32) were then randomly divided into 4 groups: the control group, the celecoxib group,the fluvastatin group and the combination group. At the end of the study, Tumor Tissues were collected for analysis. Cell apoptosis was determined by flow cytometry analysis and TUNEL assay. Akt, p-Akt and survivin protein levels were measured by Western blot. Statistical comparisons were made using factorial analysis of variance (ANOVA) and multiple comparisons between each two groups were calculated using SNK-q test.
RESULTSThe combination of Celecoxib and fluvastatin resulted in a greater inhibition of tumor growth than either agent alone, the tumor inhibitory rate was 34.0% in the Celecoxib group, 25.0% in the fluvastatin group and 72.2% in the combination group. The percentages of TUNEL--positive cancer cells in the celecoxib and fluvastatin alone treatment groups were 8.5%+/-1.4% and 9.4%+/-1.7% respectively as compared to the control group which was 3.5%+/-0.8%. Combination therapy showed a significantly greater increase in tumor cell apoptosis in comparison with the control and single-therapy groups (apoptotic index: 19.4%+/-3.0%; P value is less than 0.01 versus celecoxib or fluvastatin groups). The results of flow cytometry analysis also showed the same tendency. a small number of apoptotic cells were detected in the control tumours (4.1%+/-1.6%), whereas a large number of apoptotic cells were detected in tumours treated with celecoxib (9.1%+/-2.1%) or fluvastatin (10.1%+/-2.3%) alone; and the combination therapy resulted in even more apoptotic cells (23.6%+/-5.8%; P value is less than 0.01 versus celecoxib or fluvastatin groups). Western blot analysis demonstrated that the combination of celecoxib and fluvastatin significantly down-regulated p-Akt (0.23+/-0.08 versus 1.12+/-0.07 and surviving (0.50+/-0.07 versus 1.47+/-0.19) in BEL-7402 tumours compared with the control (P value is less than 0.01 for all).
CONCLUSIONThe present study provided evidence that treatment with celecoxib in combination with fluvastatin resulted in the inhibition of HCC tumour growth in an in vivo mouse model.

BACKGROUND/AIMS: This multicenter, open-labeled, randomized trial was performed to compare the effects of rosuvastatin 10 mg and atorvastatin 10 mg on lipid and glycemic control in Korean patients with nondiabetic metabolic syndrome. METHODS: In total, 351 patients who met the modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria for metabolic syndrome with low-density lipoprotein cholesterol (LDL-C) levels > or = 130 mg/dL were randomized to receive either rosuvastatin 10 mg (n = 173) or atorvastatin 10 mg (n = 178) for over 6 weeks. RESULTS: After 6 weeks of treatment, greater reductions in total cholesterol (- 35.94 +/- 11.38 vs. - 30.07 +/- 10.46%, p < 0.001), LDL-C (48.04 +/- 14.45 vs. 39.52 +/- 14.42%, p < 0.001), non-high-density lipoprotein cholesterol (- 42.93 +/- 13.15 vs. - 35.52 +/- 11.76%, p < 0.001), and apolipoprotein-B (- 38.7 +/- 18.85 vs. - 32.57 +/- 17.56%, p = 0.002) levels were observed in the rosuvastatin group as compared to the atorvastatin group. Overall, the percentage of patients attaining the NCEP ATP III goal was higher with rosuvastatin as compared to atorvastatin (87.64 vs. 69.88%, p < 0.001). Changes in glucose and insulin levels, and homeostasis model assessment of insulin resistance index were not significantly different between the two groups. The safety and tolerability of the two agents were similar. CONCLUSIONS: Rosuvastatin 10 mg was more effective than atorvastatin 10 mg in achieving NCEP ATP III LDL-C goals in patients with nondiabetic metabolic syndrome, especially in those with lower NCEP ATP III target level goals.

The object of this study is to investigate the pharmacokinetic interaction of pioglitazone hydrochloride and atorvastatin calcium in healthy adult Beagle dogs following single and multiple oral dose administration. A randomized, cross-over study was conducted with nine healthy adult Beagle dogs assigned to three groups. Each group was arranged to take atorvastatin calcium (A), pioglitazone hydrochloride (B), atorvastatin calcium and pioglitazone hydrochloride (C) orally in the first period, to take B, C, A in the second period, and to take C, A, B in the third period for 6 days respectively. The blood samples were collected at the first and the sixth day after the administration, plasma drug concentrations were determined by LC-MS/MS, a one-week wash-out period was needed between each period. The pharmacokinetic parameters of drug combination group and the drug alone group were calculated by statistical moment method, calculation of C(max) and AUC(0-t) was done by using 90% confidence interval method of the bioequivalence and bioavailability degree module DAS 3.2.1 software statistics. Compared with the separate administration, the main pharmacokinetic parameters (C(max) and AUC(0-t)) of joint use of pioglitazone hydrochloride and atorvastatin calcium within 90% confidence intervals for bioequivalence statistics were unqualified, the mean t(max) with standard deviation used paired Wilcoxon test resulted P > 0.05. There was no significant difference within t1/2, CL(int), MRT, V/F. Pioglitazone hydrochloride and atorvastatin calcium had pharmacokinetic interaction in healthy adult Beagle dogs.
