| abstract |
This invention describes an application of selected polymers as novel drug delivery systems which use the body temperature and pH to induce a liquid to gel transition of the polymer which contains a drug or therapeutic agent. The goal of such a delivery system is to achieve a greater degree of bioavailability or sustained concentration of a drug to a body cavity. The drug delivery system can be used in any body cavity, or as an injectable, as a topical or dermal application and/or an ophthalmic application. |
