The present invention is directed to a method of making an inclusion complex comprising an acylated cyclodextrin host molecule and a guest molecule, wherein the method comprises the steps of: a) contacting the acylated cyclodextrin host molecule and the guest molecule to form an inclusion complex; and b) precipitating the inclusion complex in an aqueous medium. The present invention is further directed to an inclusion complex comprising an acylated cyclodextrin host molecule and a guest molecule, wherein the guest molecule comprises from about 2% (wt.) to about 15% (wt.) of the inclusion complex. Moreover, the present invention relates to a composition comprising a polymer and an inclusion complex, wherein the inclusion complex comprises an acylated cyclodextrin host molecule and a guest molecule and medical devices and solid pharmaceutical compositions comprised thereof.
