Abstract
A method for making a pharmaceutical by emulsion aggregation, the method including emulsifying a first pharmaceutical agent and a biodegradable resin to form a primary emulsion of pre-aggregated particles in a slurry; aggregating the pre-aggregated particles to form aggregated pharmaceutical particles in the slurry; and isolating the pharmaceutical particles. The method may be used to make time-released, multi-formulation, and inhalable pharmaceuticals.
