Long-term efficacy and safety of rosuvastatin 40 mg in patients with severe hypercholesterolemia.

Patients with elevated low-density lipoprotein (LDL) cholesteral levels are at high risk of cardiovascular events but are often undertreated and fail to achieve lipid goals. This open-label, noncomparative, multicenter study assessed efficacy and safety of rosuvastatin 40 mg for < or =96 weeks in 1,380 patients with severe hypercholesterolemia, including heterozygous familial hypercholesterolemia. Patients > or =18 years old with fasting LDL cholesterol > or =190 and < or =260 mg/dl and triglycerides <400 mg/dl entered a 6-week dietary lead-in, before receiving rosuvastatin 40 mg for 48 weeks. An optional additional 48-week treatment period followed. The initial period had 2 primary end points: percentage of patients achieving National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III LDL cholesterol goals at 12 weeks, and long-term safety, assessed during 48 weeks by incidence and severity of adverse events (AEs) and abnormal laboratory values. Safety was the primary end point in the extension period. At 12 weeks, 83% of patients achieved NCEP ATP III LDL cholesterol goals, which were maintained during 48 and 96 weeks (81% and 84%, respectively). At 48 weeks, rosuvastatin 40 mg reduced LDL cholesterol from baseline by 52% and increased high-density lipoprotein (HDL) cholesterol by 11% (both p <0.0001). At 96 weeks, LDL cholesterol was reduced by 54% and HDL cholesterol increased by 13%. Rosuvastatin 40 mg was well tolerated during 96 weeks. The overall pattern and incidence of AEs and abnormal laboratory values were consistent with the published safety profile of rosuvastatin and higher doses of other statins. In conclusion, long-term treatment with rosuvastatin 40 mg is safe and effective in patients with severe hypercholesterolemia.

Effects of adding fenofibrate (200 mg/day) to simvastatin (10 mg/day) in patients with combined hyperlipidemia and metabolic syndrome.

Combined hyperlipidemia predisposes subjects to coronary heart disease. Two lipid abnormalities--increased cholesterol and atherogenic dyslipidemia--are potential targets of lipid-lowering therapy. Successful management of both may require combined drug therapy. Statins are effective low-density lipoprotein (LDL) cholesterol-lowering drugs. For atherogenic dyslipidemia (high triglycerides, small LDL, and low high-density lipoprotein [HDL]), fibrates are potentially beneficial. The present study was designed to examine the safety and efficacy of a combination of low-dose simvastatin and fenofibrate in the treatment of combined hyperlipidemia. It was a randomized, placebo-controlled trial with a crossover design. Three randomized phases were employed (double placebo, simvastatin 10 mg/day and placebo, and simvastatin 10 mg/day plus fenofibrate 200 mg/day). Each phase lasted 3 months, and in the last week of each phase, measurements were made of plasma lipids, lipoprotein cholesterol, plasma apolipoproteins B, C-II, and C-III and LDL speciation on 3 consecutive days. Simvastatin therapy decreased total cholesterol by 27%, non-HDL cholesterol by 30%, total apolipoprotein B by 31%, very low-density lipoprotein (VLDL) + intermediate-density lipoprotein (IDL) cholesterol by 37%, VLDL + IDL apolipoprotein B by 14%, LDL cholesterol by 28%, and LDL apolipoprotein B by 21%. The addition of fenofibrate caused an additional decrease in VLDL + IDL cholesterol and VLDL + IDL apolipoprotein B by 36% and 32%, respectively. Simvastatin alone caused a small increase in the ratio of large-to-small LDL, whereas the addition of fenofibrate to simvastatin therapy caused a marked increase in the ratio of large-to-small LDL species. Simvastatin alone produced a small (6%) and insignificant increase in HDL cholesterol concentrations. When fenofibrate was added to simvastatin therapy, HDL cholesterol increased significantly by 23%. No significant side effects were observed with either simvastatin alone or with combined drug therapy. Therefore, a combination of simvastatin 10 mg/day and fenofibrate 200 mg/day appears to be effective and safe for the treatment of atherogenic dyslipidemia in combined hyperlipidemia.

Sildenafil citrate does not reduce exercise tolerance in men with erectile dysfunction and chronic stable angina.

AIMS: The aim of this study was to evaluate whether sildenafil, used for treatment of erectile dysfunction (ED), affects the exercise tolerance and ischaemic threshold in men with exercise-induced angina not taking nitrates. METHODS: This was a double-blind placebo-controlled study in men with ED and chronic stable angina, assessing the effect of sildenafil on time to limiting angina during incremental treadmill exercise. Patients remained on their antianginal therapy and received a 100-mg dose of sildenafil or placebo 1h prior to treadmill exercise. Other measurements included times to onset of angina, 1-mm ST-segment depression, and total exercise time. RESULTS: Adjusted treatment differences for the time to limiting angina, time to onset of angina, total exercise time, and time to 1-mm ST-segment depression were (mean+/-SE) 20+/-10s (95% CI, 1-39; P=0.040), 32+/-11s (95% CI, 11-53; P=0.004), 20+/-10s (95% CI, 0-39; P=0.049), and 12+/-17s (95% CI, -21 to 45, P=0.48), respectively, in favour of sildenafil. There were no serious treatment-related adverse events. CONCLUSIONS: Sildenafil was well tolerated and did not adversely affect any exercise parameter in men with coronary artery disease and ED. Favourable trends in total exercise duration and times to onset of angina and limiting angina were recorded with sildenafil use.
