Abstract
OBJECTIVE Second-generation antipsychotics (SGAs) have a negative impact on metabolic syndrome (MetS) risk factors for their effects on body weight and on metabolic parameters. Statins are widely used in the treatment of dyslipidemia; less is known on the ability of statins to treat SGAs-induced dyslipidemia, and nutraceutical approaches may represent promising strategies in SGAs-treated patients. Red Yeast Rice (RYR), the fermented product of the Aspergillaceae mold Monascus purpureus (red yeast) grown on white rice, has been shown to have a cholesterol-lowering effect which can be ascribed to monacolin K, although other active compounds may play a role management of hyperlipidemia. The present study was aimed to explore the efficacy and safety of RYR treatment on clinical and metabolic parameters in a sample of subjects receiving SGAs. METHODS Fifteen outpatients treated with SGAs assumed RYR at the oral daily dose of 200 mg/day (total monacolin K = 11.88 mg) for 30 days. Fasting levels of triglycerides, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and glucose were determined. RESULTS RYR administration resulted in a statistically significant reduction of LDL (p = 0.029), corresponding to 11.0% decrease from baseline mean value. No significant differences in clinical and in other and metabolic parameters were observed. CONCLUSIONS Our findings suggest that RYR, at the daily dose of 200 mg for 30 days, could be a promising agent to prevent and/or treat SGAs-induced hyperlipidemia. However, future adequately-powered and well-designed studies with long-term follow-up should evaluate RYR effectiveness, as an alternative option to statins, on the SGAs-induced metabolic side effects.
