Ezetimibe is a medication used to lower cholesterol levels by blocking the absorption of cholesterol in the small intestine [1]. Research has suggested that a low-fat diet may enhance the efficacy of ezetimibe [2].
According to a study published in the Journal of Clinical Pharmacology, a low-fat diet may increase the bioavailability of ezetimibe, allowing for more effective cholesterol-lowering [3]. Another study found that a low-fat diet combined with ezetimibe resulted in greater reductions in low-density lipoprotein (LDL) cholesterol levels compared to ezetimibe alone [4].
The exact mechanisms underlying these interactions are not well understood. However, research suggests that a low-fat diet may alter the metabolic pathways involved in ezetimibe's absorption and action [5].
More research is needed to fully understand the interactions between ezetimibe and low-fat diets. Patients taking ezetimibe should consult with their healthcare providers to determine the best dietary approach for managing their cholesterol levels [6].
