The effect of fenofibrate on cardiometabolic risk factors in bromocriptine-treated women with mixed dyslipidemia: A pilot study

Background elevated prolactin levels are associated with metabolic and hormonal complications. no previous study has investigated the effect of any fibrate on plasma levels of lipids and other cardiometabolic risk factors in patients receiving dopamine agonist therapy. methods the study included 36 premenopausal women with mixed dyslipidemia and slightly increased prolactin levels,17 of whom had already been treated with bromocriptine (5.0-7.5 mg daily). the included patients received micronized fenofibrate (200 mg daily) for 6 months. plasma lipids,glucose homeostasis markers,as well as plasma levels of prolactin,uric acid,high-sensitivity c-reactive protein (hscrp),homocysteine and fibrinogen were determined before and after 12 weeks of fenofibrate therapy. results insulin sensitivity was more expressed while baseline plasma levels of hscrp and fibrinogen were lower in patients treated with bromocriptine than in women not receiving dopamine agonist therapy. although fenofibrate improved plasma lipids and insulin sensitivity,as well as reduced plasma levels of the investigated cardiometabolic risk factors in both groups of patients,its action on hdl cholesterol,triglycerides,insulin sensitivity,hscrp and fibrinogen was stronger in subjects receiving bromocriptine. moreover,only in bromocriptine-naïve patients,fenofibrate increased plasma homocysteine. conclusions our study shows that the effect of fenofibrate on plasma lipids and circulating levels of cardiometabolic risk factors may be potentiated by bromocriptine treatment. they also suggest that hyperprolactinemic women with mixed dyslipidemia and early glucose metabolism abnormalities may receive the greatest benefits from concomitant treatment with a fibrate and bromocriptine. © 2015 institute of pharmacology,polish academy of sciences.
