Stability of human growth hormone in supercritical carbon dioxide.

The instability of human growth hormone (hGH) to temperature and interfaces makes its formulation into injectable, sustained-release drug delivery systems challenging. A novel method of encapsulating hGH in polymeric microparticles has been developed using supercritical CO(2) (scCO(2)) technology, but there is limited understanding of the stability of hGH… CONTINUE READING
