Microspheres of diamide-dicarboxylic acids
 Diamide-dicarboxylic acid microspheres are provided. The diamide-dicarboxylic acids may be combined with active agent(s). The resultant composition may be in microsphere form. Also disclosed are methods for administering the microsphere and/or composition that includes the active agent. The microsphere, with or without active agent, may be prepared by (A) solubilizing, in a solvent, at least one diamide-dicarboxylic acid, to yield a first solution; and (B) contacting the first solution with a precipitator solution in which the diamide-carboxylic acid is insoluble and optionally with an active agent.
