Abstract
A therapeutic ointment having wet adherent properties and particularly well suited for delivery of medicaments to mucosal surfaces includes 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 in a polyethylene glycol ointment. Formulations of the base material with triamcinolone acetonide and lidocaine are particularly efficacious in the treatment of recurrent aphthous ulcers.
