Drug delivery coatings and devices including the same are described herein. The drug delivery coating has a first coated layer with non-ionic polymer and photogroups, a second coated layer with acid polymer in contact and hydrogen bonded with the first layer, particles with hydrophobic therapeutic agent, and cationic agent. The coating can be provided on a balloon catheter, and the particles and cationic agent can be transferred to tissue during a medical procedure, such as an angioplasty procedure, for a therapeutic effect.
