Background: Many drug and non drug approaches are utilized for the treatment of dyslipidemia; flavonoids, the major constituents of silymarin, have been proved to
positively modify lipoproteins in experimentally – induced dyslipidemia.
Objective: This study was designed to evaluate the effect of silymarin, when used alone or in combination with other hypolipidemic agents, on the lipid profile in
dyslipidemic patients.
Patients and Methods: Fifty seven patients with dyslipidaemia of various etiologies are involved in this clinical trial. They are randomized into three groups treated with
either 400mg / day silymarin (gr. A) or 20 mg / day lovastatin (gr. B) or a combination of 200 mg/day silymarin and 10 mg/day lovastatin (gr. C) for 2 months, only 45
patients complete the study . Serum lipid profile (total cholesterol, triglycerides, LDLC, VLDL-C and HDL-C) and liver functions indices (SGOT, SGPT, total bilirubin)
were evaluated each month during the follow up period.
Results: Treatment with silymarin results in a significant decrease in TC, TG, LDL-C and VLDL-C levels, with a significant elevation in HDL-C levels, without any
significant changes in liver function. Meanwhile, adjunct use of silymarin with lovastatin widens the scope of lovastatin-hypolipidemic effect, without increasing in
the score of adverse effects, and ameliorating the hepatic damage emerged due to its use.
Conclusions: The results presented in this study indicated that silymarin can be used alone in clinical practice for the treatment of dyslipidemia, and when combined with
other hypolipidemic agents like lovastatin, improves therapeutic profile and ameliorate some of its adverse effects.
