Bioerodible polymers useful for the controlled release of therapeutic agents

摘要

Bioerodible ortho ester polymers useful for preparing soft form bioerodible pharmaceutical compositions such as ointments, creams, gels and the like are provided. A novel synthetic method for preparing the polymers is provided as well. Synthesis involves a one-step reaction between a monomeric ortho ester and a triol. The pharmaceutical compositions of the invention are useful for the controlled release of therapeutic agents, and may be administered for a variety of purposes, such as for the treatment of deep wounds, including burns, and for the treatment of periodontal disease.
