Transmitter-loaded polymeric microspheres induce regrowth of dopaminergic nerve terminals in striata of rats with 6-OH-DA induced parkinsonism.


Biodegradable controlled-release microspheres made with the biocompatible biodegradable polyester excipient poly (DL-lactide-co-glycolide) represent a new technology for drug delivery to the central nervous system (CNS). A suspension of 3 microliters of dopamine (DA) or NE containing microspheres, or empty microspheres, was implanted in 2 sites of the DA… (More)
