3D Printed Pellets (Miniprintlets): A Novel, Multi-Drug, Controlled Release Platform Technology
Selective laser sintering (SLS) is a single-step three-dimensional printing (3DP) process that can be leveraged to engineer a wide array of drug delivery systems. The aim of this work was to utilise SLS 3DP, for the first time, to produce small oral dosage forms with modified release properties. As...
