A pharmaceutical composition for the sustained release of human growth hormone from a polymer matrix is disclosed. The pharmaceutical composition comprises a biocompatible polymer, particles of metal cation-complexed human growth hormone wherein said particles are dispersed within the biocompatible polymer and an aqueous injection vehicle.

Composition for sustained release of human growth hormone

The method of the invention for producing a composition for the sustained release of biologically active hGH includes dissolving a biocompatible polymer in a polymer solvent to form a polymer solution, dispersing particles of biologically active, metal cation-stabilized hGH in the polymer solution, and then solidifying the polymer to form a polymeric matrix containing a dispersion of said hGH particles.

The method of using the sustained release composition of the present invention comprises providing a therapeutically effective blood level of biologically active, non-aggregated human growth hormone in a subject for a sustained period by administering to the subject a dose of said sustained release composition.
