In various embodiments, ezetimibe-associated apoA-I mimetic peptide are provided that show improved synergistic activity between ezetimibe and the apoA-I peptide in vivo. In certain embodiments the peptide component is a transgenic 6F and the ezetimibe-associated apoA-I mimetic peptide is an Ez-T6F peptide. Methods of making the Ez-apoA-I peptides are also provided. In certain embodiments the methods involve incubating ezetimibe and an apoAI mimetic peptide (e.g., T6F) in a solution comprising ethyl acetate and acetic acid or in a solution comprising ethyl lactate and lactic acid and drying the solution to provide a dry ezetimibe-associated apoA-I mimetic peptide.
