The present invention relates to a drug-loaded filament comprising topiramate and a pharmaceutical preparation for preventing or treating obesity prepared using same. Topiramate contained in the filament exhibits an amorphous nature, and thus can be used in the preparation of a pharmaceutical preparation that is easily dissolved, thereby facilitating application and absorption in the body. The drug-loaded filament comprising same can be applied to 3D printing such as fused deposition modeling (FDM) and effectively used in the preparation of a pharmaceutical preparation that can be administered via various mucosal administration routes, such as oral mucosa, e.g., sublingual and buccal mucosa, and nasal mucosa in the nasal cavity or the like.

At present, the most prevalent pharmaceutical dosage forms, the oral immediate-release tablets and capsules, are porous solids of compacted drug and excipient powders. Upon ingestion, physiological fluid percolates the open pores, and the dosage form disintegrates and the drug dissolves. Because the pores in the compacted solids are not well connected, however, fluid percolation generally is not uniform, and the drug release rate is difficult to predict and control. To overcome such limitations, therefore, herein a structured solid dosage form is disclosed. The structured solid dosage form comprises a structural assembly of one or more repeatably arranged, extruded structural elements. The elements comprise segments separated and spaced from adjoining segments by free spacings defining one or more substantially interconnected free spaces, or channels, in the dosage form through which a physiological fluid may percolate. The disclosed dosage form enables more predictable drug release rates, and can be readily manufactured by 3D-printing.
