Pharmacotherapeutic process and composition for central nervous system disorders

摘要

The present invention is directed to a method of modulating the release of at least one endogenous compound in vivo. The method comprises delivering intranasally at least one micro-construct comprising an agonist and a pharmaceutically acceptable carrier to a locus comprising an agonist receptor and a heterologous receptor that is coupled to at least one common signaling molecule. The micro-construct used in the present inventive method provides sustained release of the agonist provided by erosion of an exterior surface defined by the micro-construct. Once released, the agonist effectively up- or down-regulates at least one signaling molecule common to both the agonist receptor and the heterologous receptor, thereby potentiating or desensitizing the heterologous receptor in order to modulate release of at least one endogenous compound under the control of the heterologous receptor.
