Abstract
Compositions and methods of making and using of microparticle compositions that provide faster flow or improved injectability through smaller or small-diameter needles have been developed. Notably, the microparticle compositions can be successfully delivered or administered through smaller-diameter needles than other microparticle compositions prepared from biocompatible or biodegradable polymers including, for example, poly(lactide), poly(lactide-co-glycolide), polycaprolactone, or poly-3-hydroxybutyrate. The microparticle compositions can exhibit a higher solids loading for a given needle size and/or faster flow through needles than other microparticle compositions. Further, blending or mixing the polymer of the microparticle composition with other polymer formulations can enhance the injectability of the resulting formulation.
