Abstract: The disclosure provides macrolide particulates including a macrolide therapeutic agent such as rapamycin at high concentration in the particulate. In one method the particulates are made by adding a composition containing an polyoxyethylene sorbitan n-acyl ester, poly(ethyleneimine), or alkylated quaternary ammonium salt to a composition including macrolide dissolved in an alcohol such as ethanol. In another method the particulates are made by adding a non-solvent composition to a composition including macrolide and an alkyl-substituted chromanol dissolved in an alcohol such as ethanol. The formed macrolide particulates have one or more desirable properties including sizes in the range of 0.1 μm to 10 μm, spherical or near spherical shapes, low polydispersity, and/or stability. The macrolide particulates can be used for therapeutic compositions, or in association with an implantable or insertable medical device, such as associated with a polymeric coating on a device.

Abstract: Embodiments of the disclosure include coatings comprising an oligomerized polyphenol layer. The oligomerized polyphenol layer can be used as an intermediate coated layer on a medical device that hydrogen bonds to a synthetic or natural polymer, which in turn can be used as a top coat or further associated with another coated layer. The multilayered coatings can provide properties such as hemocompatibility or lubricity. In other embodiments, the oligomerized polyphenol layer is used on a medical device as a hemostatic layer configured to contact blood and promote coagulation. The oligomerized polyphenol layer can also be used on the inner surface (e.g., inner diameter) of a medical device to prevent bacterial adherence. The oligomerized polyphenol layer can also be used on the surface of a in vitro diagnostic article, or a cell culture device to, promote adsorption of a biological mo lecule.
