We examined the effects of citric acid and L-carnitine administration on physical fatigue. In a double-blind, placebo-controlled, 3-way crossover study, 18 healthy volunteers were randomized to oral citric acid (2,700 mg/day), L-carnitine (1,000 mg/day), or placebo for 8 days. The fatigue-inducing physical task consisted of workload trials on a cycle ergometer at fixed workloads for 2 h on 2 occasions. Before the physical load, salivary chromogranin A, measured as a physiological stress marker, was lower in the group given citric acid than in the group given placebo. Also, after the physical load, the subjective feeling of fatigue assessed with a visual analogue scale was lower in the citric acid group than in the placebo group. In contrast, L-carnitine had no effect on chromogranin A or subjective fatigue. These results suggest that citric acid reduces physiological stress and attenuates physical fatigue, whereas L-carnitine does not.

Background:This study is the first to evaluate the short-term efficacy and long-term safety of AZD0585, a mixture of omega-3 free fatty acids, in Japanese patients with dyslipidemia.Methods and Results:In this randomized double-blind placebo-controlled Phase III study, 383 patients were randomized to 2 g AZD0585, 4 g AZD0585, or placebo once daily for 52 weeks. Eligible patients had low-density lipoprotein cholesterol (LDL-C) levels controlled regardless of statin use, and triglyceride levels between 150 and 499 mg/dL. The least-squares (LS) mean percentage changes in triglyceride concentrations from baseline to the 12-week endpoint (mean of measurements at Weeks 10 and 12) in the 2 and 4 g AZD0585 and placebo groups were −15.57%, −21.75%, and 11.15% respectively (P<0.0001 for both AZD0585 doses vs. placebo). No clinically significant changes from baseline to the 12-week endpoint in total cholesterol, LDL-C, and LDL-C/apolipoprotein (Apo) B were found with AZD0585. High-density lipoprotein cholesterol (HDL-C) was slightly increased and very low-density lipoprotein cholesterol, non-HDL-C, ApoC-II, and ApoC-III were decreased with AZD0585 compared with placebo at the 12-week endpoint. Lipid profiles up to Week 52 were consistent with those up to the 12-week endpoint. No clinically important safety concerns were raised.Conclusions:AZD0585 significantly decreased serum triglyceride levels compared with placebo at the 12-week endpoint and was generally safe and well tolerated in Japanese patients with dyslipidemia.
