Polymeric matrices were used alone, or added with processing enhancers (e.g., plasticizer and filler). The polymeric formulation containing paroxetine (30% w/w), hydroxypropylcellulose (54% w/w) and excipients (16% w/w of dicalcium dihydrate phosphate, magnesium stearate and triethylcitrate; 10:1:5 ratio) exhibited the most suitable behaviour to be extruded and 3D printed, proving that adjuvants are critical to ensure processing of the formulations.engExtrudabilityFilamentPrintability3D-printed tabletFused deposition modelling (FDM)Hot melt extrusion (HME)Paroxetine (PRX)other10.3390/msf2021005017
