Abstract
Abstract A method of inhibiting cell proliferation in mammals which comprises the local delivery of an inhibitory amount of dipyridamole. Inhibiting cell proliferation is useful for the treatment of proliferaive diseases such as vascular restonesis, scleroderma, psoriasis, and rheumatoid arthritis. This method includes the local delivery of dipyridamole to the proliferative site by various techniques including local delivery catheters, site specific carriers, implants, direct injection, or direct application.
