Abstract
Statins are the first line of therapy to reduce low-density lipoprotein cholesterol (LDL-C) in order to decrease cardiovascular events. Pitavastatin is the latest statin to be introduced to the market. Areas covered: In this article, the authors review the efficacy, safety, and tolerability of pitavastatin. The authors also review a recent cardiovascular outcome study. Expert opinion: Pitavastatin produces dose-dependent reductions in LDL-C at lower doses than other statins. The maximum approved dose of 4 mg reduces LDL-C by about 40-49% in different patient groups and is equivalent to atorvastatin 20 mg in this effect. Pitavastatin undergoes minimal metabolism so drug-drug interactions are less likely than with many other statins, but it can interact with some drugs that inhibit drug transporters. Compared with other statins, it has been associated with greater increases in high-density lipoprotein cholesterol and it was found to be less likely to cause new onset diabetes. In a recent study in Japanese patients with stable coronary artery disease, pitavastatin 4 mg was more effective than pitavastatin 1 mg in reducing cardiovascular events. Therefore, the highest dose may be preferred in high-risk patients.

Abstract
BACKGROUND Statins have proven efficacy in inhibiting the onset and progress of atherosclerosis. The effectiveness of pitavastatin in reversing carotid atherosclerosis associated with hypercholesterolemia (HC) is unknown. OBJECTIVES To explore the simultaneous effects of pitavastatin calcium on brachial arterial flow-mediated vasodilatation (FMD), carotid intima-media thickness (IMT), and arterial stiffness (β), three surrogate markers of atherosclerosis were studied in HC patients. METHODS A randomized, double-blind trial was performed with 40 HC subjects who fulfilled the inclusion/exclusion criteria. Patients were given pitavastatin calcium 1 mg/d (Group 1) or 2 mg/d (Group 2) for 8 weeks. There were 20 patients in each group, and 30 gender- and age-matched healthy subjects as controls were recruited. FMD of the brachial artery, carotid IMT, and arterial stiffness indicated by β were measured at baseline and at 8 weeks after starting pitavastatin calcium therapy using ultrasound techniques. Biochemical tests were also made on all subjects. RESULTS At baseline, higher total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), reduced FMD, and increased β and IMT were observed in HC patients (P<0.001 for all) compared with controls. After 8 weeks, TC was decreased by 20.59%/27.56% and LDL-C 30.92%/35.64%, respectively, in comparison to baseline groups; the HC groups had reduced β and improved endothelial function over the 8-week follow-up (P<0.05-0.001); nonetheless, no significant alterations of IMT were found (P>0.05). Significant negative interactions between TC/LDL and FMD (P<0.05-0.001), positive interactions between TC and IMT (P=0.003) and between TC/LDL and β (P<0.001-0.000) were found. CONCLUSIONS Treatment with pitavastatin calcium exerted favorable effects on endothelial function and arterial stiffness. It also improved carotid atherosclerosis in patients with HC.

Abstract
BACKGROUND AND OBJECTIVES It is well established by a large number of randomized controlled trials that lowering blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) by drugs are powerful means to reduce stroke incidence, but the optimal BP and LDL-C levels to be achieved are largely uncertain. Concerning BP targets, two hypotheses are being confronted: first, the lower the BP, the better the treatment outcome, and second, the hypothesis that too low BP values are accompanied by a lower benefit and even higher risk. It is also unknown whether BP lowering and LDL-C lowering have additive beneficial effects for the primary and secondary prevention of stroke, and whether these treatments can prevent cognitive decline after stroke. RESULTS A review of existing data from randomized controlled trials confirms that solid evidence on optimal BP and LDL-C targets is missing, possible interactions between BP and LDL-C lowering treatments have never been directly investigated, and evidence in favour of a beneficial effect of BP or LDL-C lowering on cognitive decline is, at best, very weak. CONCLUSION A new, large randomized controlled trial is needed to determine the optimal level of BP and LDL-C for the prevention of recurrent stroke and cognitive decline.
