Exploring Fused Deposition Modeling (Fdm) Three-Dimensional Printing Tablet Design Options For Pharmaceutical Dosage Forms, Guluzar Gorkem Buyukgoz
Exploring Fused Deposition Modeling (Fdm) Three-Dimensional Printing Tablet Design Options For Pharmaceutical Dosage Forms, Guluzar Gorkem Buyukgoz
Dissertations
This dissertation examines the use of Fused Deposition Modeling (FDM) based three-dimensional (3D) printing approach for developing patient-specific dosage forms and addressing related technical challenges in such drug delivery systems. The first main objective is to explore pharmaceutical tablet design options using novel FDM 3D printing technology as the drug delivery platform such that drug form and tablet properties are tailored by considering patient age-specific formulations and dissolution control. Of the five different design options, two proposed options meet the main objective of providing similar drug release, whereas the popular option of fixed drug concentration but differing tablet size could …
Development Of Site - Specific Drug Delivery Systems Using Hot Melt Extrusion And Fused Deposition Modeling 3d Printing, Nagireddy Reddy Dumpa
Development Of Site - Specific Drug Delivery Systems Using Hot Melt Extrusion And Fused Deposition Modeling 3d Printing, Nagireddy Reddy Dumpa
Electronic Theses and Dissertations
Due to preferential site of drug absorption and the need for increased concentration of medication at the required tissues, dosage forms should be designed or formulated in such a way that medication is released at a specific site or after a specific time in the gastrointestinal tract (GIT). Knowledge of transit times of dosage forms in each part of GIT, by use of particular polymers or employing specific delivery systems such as floating systems, delivery of medication to specific sites in the GIT can be achieved. HME coupled FDM 3D printing has the capability to create customized dosage forms for …
Development Of Ibuprofen Tablet With Polyethylene Oxide Using Fused Deposition Modeling (Fdm) 3d Printing Coupled With Hot-Melt Extrusion, Sooyeon Chung
Electronic Theses and Dissertations
Ibuprofen is known to plasticize several polymers used in the pharmaceutical field, and it is considered challenging to achieve an immediate release by fused deposition modeling (FDM). Therefore, this study aimed to print ibuprofen tablet with a focus on achieving immediate release. Polyethylene oxide (Polyox WSR N80) was used as a main matrix to form the ibuprofen filament due to its water-soluble property and manifesting suitable mechanical property even with the high drug loading (40% w/w). Several release modifiers such as Kollidon VA64, Kollidon 12PF, Kollicoat IR, Kollidon CL, and Mannitol were added separately to the formulation to enhance the …
