Summary:Disclosed are drug delivery devices, coatings, and microparticles that achieve sufficiently small particle sizes with high loading of Rapamycin. In an embodiment, a balloon comprises a coating on its exterior surface, the coating comprising microparticles having a Dv90 particle size of from 1 to 11 µm, as measured with static laser scattering, the microparticles comprising from 35 to 50 wt% of rapamycin, based on the total weight of the microparticles, and a random copolymer according to Formula (I). L'invention concerne des dispositifs d'administration de médicament, des revêtements et des microparticules permettant d'obtenir des tailles de particule suffisamment petites avec une charge élevée de rapamycine. Dans un mode de réalisation, un ballonnet comprend un revêtement sur sa surface extérieure, le revêtement comprenant des microparticules présentant une taille de particule Dv90 de 1 à 11 µm, mesurée par diffusion laser statique, les microparticules comprenant de 35 à 50 % en poids de rapamycine, sur la base du poids total des microparticules, et un copolymère aléatoire selon la formule (I).
