Pharma-inks (drug-loaded inks) containing hydrocortisone (HC) were developed and characterised based on their rheological properties and drug content. Different strategies were investigated to improve HC solubility: formation of β-cyclodextrin complexes, Soluplus® based micelles, and the use of co-solvent systems. The software automatically adapted the data matrix size and identified the number of layers for printing. HC content deposited in each film layer was measured, and it was found that the proportion of co-solvent used directly affected the drug solubility and simultaneously played a role in the modification of the viscosity and surface tension of the inks. The formation of β-cyclodextrin complexes improved the drug quantity deposited in each layer. On the contrary, micelle-based inks were not suitable for printing. Orodispersible films containing flexible and low doses of personalised HC were successfully prepared, and the development of a code generator software oriented to medical use provided an additional, innovative, and revolutionary advantage to personalised medicine safety and accessibility. date: 2024-04-25 date_type: published publisher: Elsevier BV official_url: https://doi.org/10.1016/j.ijpharm.2024.124005 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2261603 doi: 10.1016/j.ijpharm.2024.124005 medium: Print-Electronic pii: S0378-5173(24)00239-4 lyricists_name: Basit, Abdul lyricists_name: Januskaite, Patricija lyricists_id: ABASI56 lyricists_id: JANUS91 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: International Journal of Pharmaceutics volume: 655 article_number: 124005 event_location: Netherlands issn: 0378-5173 citation: Rodríguez-Pombo, L; Carou-Senra, P; Rodríguez-Martínez, E; Januskaite, P; Rial, C; Félix, P; Alvarez-Lorenzo, C; ...
