Patent ID: 11793820

Abstract:
Embodiments include formulations and methods for oromucosal administration of a dry powder to create a topical foam composition to deliver medicaments to an interior mucosal space, such as the oral cavity, nasal cavity, rectal cavity, vaginal cavity or esophagus. The active agent can be amifostine, an antibiotic, an anti-fungal, a non-steroidal anti-inflammatory drug or a steroidal anti-inflammatory drug. Oromucosal delivery allows one to target oral epithelial cells. Embodiments also include methods of treating mucositis. Conventional formulations and methods are generally ineffective because drugs cannot be directed toward epithelial cells of the GI that are most susceptible to mucositis. The formulations described herein increase concentration, permeability and residence time at a target site. The formulations also allow stable forms of amifostine, which obviates difficulties associated with storing, dosing and administering the drug.
