In vivo Characterization of Sustained-Release Formulation of Recombinant Human Growth Hormone in Immunosuppressed Rats and Dogs

Abstract

The in vivo release characteristics of rhGH-loaded PLGA microsphere prepared using a double emulsion process from hydrophilic 50:50 poly(D.L-lactide-co-glycolide) (PLGA) polymers were analyzed. This formulation showed particle size of ca 53.1$\mu\textrm{m}$ with high drug incorporation efficiency. To investigate in vivo release kinetics without the interference of formation of antibodies to rhGH in the experimental animals, the animals were immunosuppressed by treatment with Cyclosporin.
