ABSTRACT:
Hydrophobically-modified bioadhesive polyelectrolytes containing a bioadhesive polyelectrolyte and a hydrophobic component are disclosed. Also disclosed are polyelectrolyte-agent compositions wherein the hydrophobically-modified bioadhesive polyelectrolyte is loaded with a pharmaceutically, cosmetically, or prophylactically acceptable agent. Suitable agents have hydrophobic and/or ionic character, and include drugs. The polyelectrolyte-agent compositions may be formulated for administration by topical, oral and/or systemic routes. Methods of administering such agents to an animal are also disclosed, and include administration of an effective amount of the polyelectrolyte-agent composition to the animal.
