RESUMO
BACKGROUND: Supplements are commonly used by individuals with indications for lipid-lowering therapy, but evidence of their effectiveness to lower low-density lipoprotein cholesterol (LDL-C) is lacking, particularly when compared with statins. OBJECTIVES: The trial objective was to compare the efficacy of a low-dose statin with placebo and 6 common supplements in impacting lipid and inflammatory biomarkers. METHODS: This was a single-center, prospective, randomized, single-blind clinical trial among adults with no history of atherosclerotic cardiovascular disease (ASCVD), an LDL-C of 70 to 189 mg/dL, and an increased 10-year risk of ASCVD. Participants were randomized to rosuvastatin 5 mg daily, placebo, fish oil, cinnamon, garlic, turmeric, plant sterols, or red yeast rice. The primary endpoint was the percent change in LDL-C from baseline for rosuvastatin 5 mg daily compared with placebo and each supplement after 28 days. The primary endpoint was evaluated in a hierarchical fashion with rosuvastatin first compared with placebo, then each supplement in a prespecified order using analysis of covariance. RESULTS: A total of 190 participants completed the study. The percent LDL-C reduction with rosuvastatin was greater than all supplements and placebo (P < 0.001). The difference in LDL-C reduction with rosuvastatin compared with placebo was -35.2% (95% CI: -41.3% to -29.1%; P < 0.001). None of the dietary supplements demonstrated a significant decrease in LDL-C compared with placebo. Adverse event rates were similar across study groups. CONCLUSIONS: Among individuals with increased 10-year risk for ASCVD, rosuvastatin 5 mg daily lowered LDL-C significantly more than placebo, fish oil, cinnamon, garlic, turmeric, plant sterols, and red yeast rice.

The efficacy and safety of nisoldipine-extended release (ER) and amlodipine were compared in a 6-week multicenter, randomized, double-blind, double-dummy, parallel group, titration-to-effect trial in patients with stage 1 to 2 systemic hypertension (90 to 109 mm Hg diastolic blood pressure [BP]) and chronic stable angina pectoris. After a 3-week placebo run-in period, patients (n = 120) were randomly assigned to active treatment with either nisoldipine-ER (20 to 40 mg) or amlodipine (5 to 10 mg) once daily, titrated as necessary after 2 weeks to achieve diastolic BP <90 mm Hg. After 6 weeks, the mean reduction in systolic/diastolic BP from baseline was 15/13 mm Hg with nisoldipine-ER and 13/11 mm Hg with amlodipine (p = NS/p = NS). Both drugs resulted in similar BP responder rates (diastolic BP <90 mm Hg in 87% of patients who received nisoldipine-ER and 78% of patients on amlodipine, p = NS) and anti-ischemic responder rates (increasing exercise time >20% in 20% and 27%, respectively [p = NS], and increasing exercise time >60 seconds in 32% and 29% of patients, respectively [p = NS]. Also, after 6 weeks of active therapy, there was a similar mean increase in total exercise duration (23 seconds in the nisoldipine-ER group and 21 seconds in the amlodipine group, p = NS). Neither drug increased heart rate and both decreased frequency of anginal episodes. Adverse events were infrequent, and typically were vasodilator-related effects (including headache and peripheral edema) that occurred with somewhat higher incidence in the nisoldipine-ER group. Thus, nisoldipine-ER and amlodipine provided comparable antihypertensive and anti-ischemic efficacy, and both were generally well tolerated.
