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.

Injectable delivery of microparticles and compositions therefor

The present invention relates to emulsion and double-emulsion based processes for preparing microparticles. The invention also relates to workhead assemblies for in-line flow-through mixing devices that can be used for mixing two or more fluids. The workhead assemblies can be used with the processes for preparing microparticles.

Injectable delivery of microparticles and compositions therefore

Disclosed are terpolymer compositions of lactide, glycolide, and caprolactone and methods of making such polymers with an initiator. Methods of using the terpolymers as a drug delivery platform are also disclosed.

Viscous terpolymers as drug delivery platform

Disclosed herein are process for preparing cyclic esters comprising unsaturated functional groups. Also disclosed are copolymers prepared from the cyclic esters. The copolymers can be used to form microparticles, polymer micelles, etc., which are useful in drug delivery applications.

An injectable slow-release methadone, partial opioid agonist or opioid antagonist formulation is provided comprising methadone, a partial opioid agonist or opioid antagonist in a poly(D,L-lactide) excipient with a small amount of residual ethyl acetate. Upon intramuscular or subcutaneous injection of the composition, methadone, a partial opioid agonist or opioid antagonist is released in a controlled manner over an extended period of time. The composition finds use in the treatment of heroin addicts and alcoholics to reduce consumption of the abused substances. Of particular interest are the drugs buprenorphine, methadone and naltrexone.
