Abstract: The invention comprises a ready to use film dosage form comprising microemulsion of an Active Pharmaceutical Ingredient embedded or immobilized in a thin polymeric matrix as a double microemulsion and a process of making the same. The microemulsion in the film dosage form of this invention is capable of being absorbed through mucosal route. The process of making the film dosage of this invention comprises steps of forming a film forming dispersion containing film forming polymers, excipients and microemulsion of active pharmaceutical ingredient, casting the same in the form of a film and drying the cast of the film being carried out by means of drying conditions that suit to retain stability of the active pharmaceutical ingredient being selected such that drying of the film is achieved retaining the moisture trapped in the microemulsion embedded in the polymeric film.

Abstract: This invention comprises a method of transmucosal delivery of process of Vitamin B12 without the need of intrinsic factor comprising administering a solid composition comprising a Vitamin B12 and at least one bifunctional macromolecule with hydrophilic exterior and with hydrophobic pockets capable of pocketing Vitamin B12 material, illustrated by cyclodextrin, at least one permeation enhancer, illustrated by Isopropyl Myristate and at least one agent that is mucoadhessive as well as penetration enhancer, illustrated by chitosan. The solid composition of Vitamin B12 of claim 2 may comprise a lozenge, a candy, a wafer, a tablet, a patch, a film, a spray, a lip balm, or gum.
