Abstract
Microparticle carriers, particularly protein-encapsulated microbubbles, are used to deliver antiproliferative drugs to target sites in a subject. In particular, antirestenotic drugs are delivered to areas of vascular injury for treatment or prevention of hyperproliferative disease, e.g. stenosis, in blood vessels; and antineoplastic drugs are targeted to tumor sites.
