Hydroxypropylmethylcellulose (HPMC), also known as Hypromellose, is a traditional pharmaceutical excipient widely exploited in oral sustained drug release matrix systems. The choice of numerous viscosity grades and molecular weights…

Adequate aqueous solubility of active pharmaceutical ingredients (APIs) is a crucial factor for therapeutic effectiveness. Today, more than fifty percent of the new potential APIs are exhibiting poor aqueous solubility/dissolution rate,…

One of the major challenges for modern formulation development is the increasing number of poorly water-soluble drugs. A common formulation approach to improve the solubility of those poorly soluble active ingredients is to formulate them…

Direct powder three-dimensional (3D)-printing (DPP) of tablets to simplify fused deposition modelling (FDM) was explored. The FDM paradigm involving hot-melt extrusion for making 3D-printable drug-loaded filaments as intermediate products…

Hot-melt extrusion (HME) is increasingly applied in the pharmaceutical industry for the formulation of solid dispersions of drugs with improved solubility and release. However, tableting of milled extrudates may present problems due to…

Drug delivery of poorly soluble drugs in form amorphous solid dispersions (ASDs) is an appealing method to increase in vivo bioavailability. For rational formulation design, a mechanistic understanding of the impact of surfactants on the…

As a biopharmaceutical classification system Class IV drug, lopinavir (LPV) shows relatively poor water solubility and permeation in vivo. In the study, we developed novel solid dispersions (SD) of LPV to improve its bioavailability and to…
