ABSTRACT:
The invention provides a medicament for topically treating aphthous ulcers in the oral mucosa, and methods of use. The medicament comprises a troche or powder comprising a dry dosage of one or more antibiotics and, preferably, one or more polyvalent metal compounds. The troche or powder is directly applied to the aphthous ulcer and dissolves in saliva, within about 5 to about 15 minutes, thereby directly delivering a supratherapeutic dosage of the antibiotic to the ulcerated oral tissue. Further, in a preferred embodiment the troche/powder directly delivers a therapeutically high concentration of a polyvalent metal compound in suspension to the aphthous ulcer, thereby forming a protective barrier over the ulcerated oral tissue.
