Delivery of therapeutic proteins Pisal DS; Kosloski MP; Balu-Iyer SVJ Pharm Sci 2010[Jun]; 99 (6): 2557-75The safety and efficacy of protein therapeutics are limited by three interrelated pharmaceutical issues, in vitro and in vivo instability, immunogenicity and shorter half-lives. Novel drug modifications for overcoming these issues are under investigation and include covalent attachment of poly(ethylene glycol) (PEG), polysialic acid, or glycolic acid, as well as developing new formulations containing nanoparticulate or colloidal systems (e.g., liposomes, polymeric microspheres, polymeric nanoparticles). Such strategies have the potential to develop as next generation protein therapeutics. This review includes a general discussion on these delivery approaches.|Chemistry, Pharmaceutical[MESH]|Half-Life[MESH]|Humans[MESH]|Liposomes/pharmacokinetics[MESH]|Microspheres[MESH]|Nanoparticles/chemistry[MESH]|Polyethylene Glycols/chemistry[MESH]|Polymers/chemistry[MESH]|Proteins/*administration & dosage[MESH]|Sialic Acids[MESH] |
