Compositions for mucosal delivery of agents
Compositions and methods for mucosal delivery of agents are provided. The compositions are intended for administration to mucosal surface, such as oral, gastrointestinal and nasal mucosa. The compositions provided contain one or more mucoadhesive proteins and an agent to be delivered. Methods for delivery of agents using the compositions provided herein are also provided.

a mucoadhesive protein present at a concentration of about 9% by weight up to about 10% by weight of the total weight of the composition;
an agent for delivery; and
a delivery vehicle associated with the agent; wherein:
the composition is formulated for mucosal delivery to the oral or gastrointestinal mucosa or nasal or lung mucosa;
the mucoadhesive protein is associated with the delivery vehicle;
the mucoadhesive protein is associated with the delivery vehicle via a chemical or physical bond; and

19. A method for mucosal delivery of an agent, comprising:
contacting the composition of claim 1 with a mucosal surface of a subject, whereby the agent is delivered into the circulatory system of the subject.
20. The method of claim 19 , wherein the agent is selected from among antidiabetics, anticonvulsants, analgesics, antiparkinsons, anti-inflammatories, calcium antagonists, anesthetics, antimicrobials, antimalarials, antiparasitics, antihypertensives, antihistamines, antipyretics, alpha-adrenergic agonists, alpha-blockers, biocides, bactericides, bronchial dilators, beta-adrenergic blocking drugs, contraceptives, cardiovascular drugs, calcium channel inhibitors, depressants, diagnostics, diuretics, electrolytes, enzymes, hypnotics, hormones, hypoglycemics, hyperglycemics, muscle contractants, muscle relaxants, neoplastics, glycoproteins, nucleoproteins, lipoproteins, ophthalmics, psychic energizers, sedatives, steroids, sympathomimetics, parasympathomimetics, tranquilizers, urinary tract drugs, vaccines, vaginal drugs, vitamins, minerals, nonsteroidal anti-inflammatory drugs, angiotensin converting enzymes, polynucleotides, polypeptides, polysaccharides, nutritional supplements and combinations thereof.
