Fast-acting oral disintegration for the administration of local anesthetics to reduce physical and psychological discomfort in the oral cavity during procedures such as dental procedures, or to generally relieve pain such as toothache Film (ODF). ODF is an active pharmaceutical ingredient such as a therapeutically acceptable amount of lidocaine free base, such as about 24 mg, or a pharmaceutically acceptable salt thereof, at least one primary hydrophilic film-forming polymer, at least one A secondary hydrophilic film-forming polymer is included, wherein the weight ratio of primary hydrophilic film-forming polymer to secondary hydrophilic film-forming polymer is from about 1: 1 to about 20: 1. The ODF further comprises a plasticizer, wherein the ratio of the total weight of the primary and secondary hydrophilic film-forming polymer to the weight of the plasticizer is from about 4: 1 to about 4: 3.
