Abstract
For the last 40 years, praziquantel has been the standard treatment for schistosomiasis, a neglected parasitic disease affecting more than 250 million people worldwide. However, there is no suitable paediatric formulation on the market, leading to off-label use and the splitting of commercial tablets for adults. In this study, we use a recently available technology, direct powder extrusion (DPE) three-dimensional printing (3DP), to prepare paediatric Printlets™ (3D printed tablets) of amorphous solid dispersions of praziquantel with Kollidon® VA 64 and surfactants (Span™ 20 or Kolliphor® SLS). Printlets were successfully printed from both pellets and powders obtained from extrudates by hot melt extrusion (HME). In vitro dissolution studies showed a
greater than four-fold increase in praziquantel release, due to the formation of amorphous solid
dispersions. In vitro palatability data indicated that the printlets were in the range of praziquantel
tolerability, highlighting the taste masking capabilities of this technology without the need for
additional taste masking excipients. This work has demonstrated the possibility of 3D printing
tablets using pellets or powder forms obtained by HME, avoiding the use of filaments in fused
deposition modelling 3DP. Moreover, the main formulation hurdles of praziquantel, such as low
drug solubility, inadequate taste, and high and variable dose requirements, can be overcome using
this technology.
