Abstract
Disclosed are a cationic nanodrug, a preparation method therefor, and a drug-loaded implantable medical device, wherein the cationic nanodrug comprises a vector and a drug loaded on the vector, and the vector comprises one or more of a cationic amphipathic compound and a cationic modifier; the cationic amphipathic compound is a cationic amphipathic compound containing amino and/or acyl; and the cationic modifier is a cationic modifier containing amino and/or acyl. The cationic nanodrug greatly improves the uptake of a drug by cells and has a good slow-release effect.
