However, there was an indication of crystallinity in the granules with two peaks visible at These peaks align well with the peaks identified in the diffraction pattern of the crystalline paracetamol form I, indicating no polymorphic change caused during the granulation process.
In the diffraction pattern of the APF printed tablets, these peaks have disappeared suggesting paracetamol is mainly amorphous within the printed tablets agreeing with the FTIR data. The physical mixture showed low intensity of the peaks associated with paracetamol, most likely due to the heterogeneous sampling of the powder mixtures.
Sampling the whole granule therefore gives information about the surface of the material and sampling a cross section gives information about the bulk. In this particular case, large granules were used and sectioned to reveal the inner cross-section. The spectra of outer surfaces of the granules contain all the main peaks associated with the presence of crystalline paracetamol. This result indicates paracetamol is crystalline on the outer surfaces of the granules and amorphous inside the granules.
These observations may be attributed to the drying process of the granules. Water was used as the granulating fluid in this study which could dissolve a certain proportion of the crystalline paracetamol, but not Eudragit. During drying of the granules, water containing dissolved paracetamol migrated to the surface prior to being evaporated, leaving paracetamol to concentrateon the outer surface of the granules and recrystallise.
The spectra of the printed tablets are very similar to the ones of the inner surfaces of the granules, in which only the presence of amorphous paracetamol can be identified. This is in good agreement with the DSC results and literature data on similar solid dispersions containing amorphous paracetamol, confirming the drug is in an amorphous state in the printed tablets [ 48 , 49 ]. Drug content assays of printed material were measured at Results were compared to existing pharmacopeia regulations for batch produced tablets as a guide for assessing the accuracy and reliability requirements necessary for pharmaceutical solid dosage form approval.
The European Pharmacopoeia test for uniformity of content Ph. The drug content uniformity results of the APF printed tablets were within We recognise that the sampling of the tablets here reported does not conform to current pharmacopeia regulations which are predicated on large scale production of tablets.
We do not seek therefore to conform to the European Pharmacopoeia test for uniformity of content Ph. The in vitro drug release data of the APF printed tablets with different infills are shown in Fig. As Eudragit is soluble at pH 1. All the tablets easily satisfied these requirements indicating the suitability of Eudragit E PO for immediate release applications.
It is difficult to conclude directly from the dissolution profiles whether the drug release kinetics of the tablets with different infills are statistically significant from one another. Therefore, the mean dissolution time MDT was introduced and calculated.
These results confirmed that although infill can be used as a tool for modulating drug release, care should be taken with the increments needed to induce significant change in drug release kinetics.
This study is the first report on using APF to print solid porous dosage forms via direct granule feeding. The results demonstrated for the first-time direct 3D printing of a brittle pharmaceutical polymer, Eudragit E, without the need for any additives. This new process also bypasses the filament making process and significantly reduces the risk of thermally induced instabilities of the drug and excipients in comparison to conventional filament fusion-based 3D printing. Granulation is a mature pharmaceutical manufacturing process.
It allows the compounding of powder from raw materials into granules to avoid the direct handling of powders as an intermediate during 3D printing, which reduces the complexity of the infrastructure requirement for powder handling and the risk associated for operators.
