Bcs class iv oral drugs and absorption windows: Regional-dependent intestinal permeability of furosemide
(MDPI AG, 2020)
Biopharmaceutical classification system (BCS) class IV drugs (low-solubility low-permeability) are generally poor drug candidates, yet, ~5% of oral drugs on the market belong to this class. While solubility is often ...
Digital light processing (DLP) 3D printing of atomoxetine hydrochloride tablets using photoreactive suspensions
(MDPI AG, 2020)
Three-dimensional (3D) printing technologies are based on successive material printing layer-by-layer and are considered suitable for the production of dosage forms customized for a patient’s needs. In this study, tablets ...
Insight into the formation of glimepiride nanocrystals by wet media milling
(MDPI, 2020)
Nanocrystal formation for the dissolution enhancement of glimepiride was attempted
by wet media milling. Di erent stabilizers were tested and the obtained nanosuspensions were
solidified by spray drying in presence of ...
