    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 herein relate to active agent depots formed in situ and related methods. In various embodiments, a method of forming an active agent depot in situ is included. The method can include contacting a composition with a vessel wall, wherein the composition includes an active agent and a fibrin promoting vessel wall transfer agent wherein the ratio of active agent to fibrin promoting vessel wall transfer agent (wt./wt.) is at least 5:1. The method also includes transferring the composition from a device surface to the vessel wall surface. The method also includes forming a fibrin matrix around the composition. Other embodiments are also included herein.
