Monascus purpureus for statin and ezetimibe intolerant heterozygous familial hypercholesterolaemia patients: A clinical study

Hypercholesterolaemia is a major risk factor for cardiovascular disease and requires effective therapy in affected patients. Statins, the mainstay of lipid-lowering therapy, can cause side effects, including myalgia, in some patients. Ezetimibe, is frequently used as an add-on therapy for statins, and is also used as a monotherapy in statin-intolerant patients, however elevations in liver transaminases can occur. We examined the lipid-lowering efficacy of the natural fungal product Monascus purpureus (MP), which contains the natural statin monacolin K.

Fifty-five patients with familial hypercholesterolaemia who had discontinued statins due to muscle symptoms. Patients were placed on a lipid-lowering diet cholesterol-lowering diet (1500-1800 kcal daily, 30% lipids, 19% proteins and 52% carbohydrates). MP was added to the diet at a dose of 300 mg (providing monacolin K 10 mg). Patients were followed for 12 months. Lipid profiles and adverse event data were collected in the normal course of patient care.

After 6 months of treatment with MP and diet therapy, statistically significant changes in low-density lipoprotein cholesterol were evident (-17% for males, -16% for females; p < 0.005) Levels fell to -24% and -27% respectively at 12 months. No patients experienced elevated serum aminotransferases or C-reactive protein levels.

MP is a viable option for lipid-lowering therapy in statin-intolerant patients with hypercholesterolaemia, with good efficacy and safety profiles.
