Enhanced loading of solutes into polymer gels and methods of use |
| abstract |
A method of loading a drug into a crosslinked polymer network and protecting the drug from the effects of inactivation is described. The method includes the steps of contacting of a biologically active solute (i.e., drug) with: (i) a gel network; (ii) a second protectant polymer that is somewhat immiscible with the gel; and (iii) a protectant salt, under conditions sufficient for the biologically active solute to selectively partition into the gel and the protectants to be entrained in the gel. A drug delivery system is also described. It comprises a polymer gel network including the drug to be delivered; protectants including a salt and a loading polymer, the salt and the loading polymer capable of protecting the drug from loss of activity. The polymer gel network is capable of expanding or collapsing in response to a change in an environmental condition to which the gel is exposed, the expanding or collapsing sufficient to release the drug into an environment of use. |
