3D-Printing with precise layer-wise dose adjustments for paediatric use via pressure-assisted microsyringe printing
The establishment of 3D-printing as manufacturing process for oral solid dosage forms enables new options for the individualized medicine. The aim of this work was to develop a novel drug-printing model using pressure-assisted microsyringe (PAM) technology, which allows the precise dispensing of drug substances. Printed tablets with different numbers of layers, mimicking different doses for pediatric subgroups, were analyzed regarding mass variation, friability, thickness and disintegration time. Furthermore, the uniformity of dosage units and the dissolution behavior were investigated. Friability was
Investigation of semi-solid formulations for 3D printing of drugs after prolonged storage to mimic real-life applications
The implementation of tailor-made dosage forms is currently one of the biggest challenges in the health sector. Over the last years, different approaches have been introduced to provide an individual and precise dispensing of the appropriate dose of an active pharmaceutical ingredient (API). A more recent approach, which has been intensively researched in the last years, is 3D-printing of medicines. The aim of this work was to develop printing formulations free of organic solvents for a pressure-assisted microsyringe printing method (PAM), which should also be printable over several days of storage. Furthermore, the printed dosage forms should provide a sustained…
On-demand manufacturing of immediate release levetiracetam tablets using pressure-assisted microsyringe printing
Fast and accurate manufacturing of individually tailored solid dosage forms is one of the main challenges for personalized medicine. The use of 3D printers has recently been studied to determine their suitability for personalized drug manufacturing. In the current work, formulations free of organic solvents were developed for a pressure-assisted microsyringe printing method (PAM). The water soluble polymer polyvinyl alcohol-polyethylene glycol graft copolymer (PVA-PEG) was used as matrix, while levetiracetam (LEV) was used as model drug. Furthermore, the influence of a second polymer, polyvinylpyrrolidone-vinyl acetate copolymer (PVP-PVAc) on the properties of the printed tablets was investigated. Tablets were printed using…
