Abstract
A tacrolimus drug-eluting stent manufacturing method according to the present invention enables a tacrolimus drug to be strongly and stably bound onto a stent, while also not necessarily involving a separate step of introducing a surface-binding functional group for the binding of a drug onto a stent and a step of introducing, into the drug, a functional group capable of binding to the surface-binding functional group, and a tacrolimus drug-eluting stent manufactured by the manufacturing method has a greater total drug elution amount and has a more excellent delayed drug-elution property.
