Abstract

A therapeutic composition having wet adherent properties and particularly useful for delivery of medicaments to mucosal surfaces comprises a therapeutically effective amount of a medicament dispersed in a base material comprising from about 3 to 15% by weight of a water soluble salt of a copolymer of methyl vinyl ether and maleic acid or anhydride and from about 85 to 97% by weight of polyethylene glycol. Formulations of the base material with triamcinolone acetonide and lidocaine are particularly efficacious in the treatment of recurrent aphthous ulcers.
