Smart design approaches for orally administered lipophilic prodrugs to promote lymphatic transport
Challenges to effective delivery of drugs following oral administration has attracted growing interest over recent decades. Small molecule drugs (<1000 Da) are generally absorbed across the gastrointestinal tract into the portal blood and further transported to the systemic circulation via the…

Relative bioavailability enhancement of simvastatin via dry emulsion systems: comparison of spray…
Comprehensive comparisons of similar lipid based drug delivery systems produced by different technologies are scarce. Spray drying and fluid bed layering technologies were compared with respect to the process and product characteristics of otherwise similar simvastatin loaded dry emulsion systems.…

A 3D-Printed Polymer–Lipid-Hybrid Tablet towards the Development of Bespoke SMEDDS Formulations
3D printing is a rapidly growing area of interest within pharmaceutical science thanks to its versatility in creating different dose form geometries and drug doses to enable the personalisation of medicines. Research in this area has been dominated by polymer-based materials; however, for poorly…

Improved Bioavailability of Poorly Water-Soluble Drug by Targeting Increased Absorption through…
Itraconazole (ITZ) is a class II drug according to the biopharmaceutical classification system. Its solubility is pH 3-dependent, and it is poorly water-soluble. Its pKa is 3.7, which makes it a weak base drug. The aim of this study was to prepare solid dispersion (SD) pellets to enhance the release…

Application of Insoluble Excipients in Solid Dispersion of Chinese Medicines
In recent years, as the great success of arteannuin in the area of antimalarial treatment and commercial benefit, traditional Chinese medicine (TCM) has received great attention. However, most of the active pharmaceutical ingredients (API) of Chinese medicines are hydrophobic, which causes the low…

The impact of quantity of lipid based formulations with different compositions on the oral…
In this study, the effect of the quantity of lipid-based formulations (LBFs) on the oral absorption of ritonavir (RTV), a model for poorly water-soluble drugs, was investigated. Two types of LBFs, comprising short- and medium-chain lipids (LBF-SMC) and long-chain lipids (LBF-LC) loaded with…

Application of TPGS as an efflux inhibitor and a plasticizer in baicalein solid dispersion
The oral bioavailability and efficacy of baicalein is dramatically limited by its low solubility and effect of efflux. In our study, we chose PVP-VA64 as a carrier and TPGS as a plasticizer and efflux inhibitor to prepare a solid dispersion of baicalein using hot-melt extrusion technology to improve…

Cellulosic Polymers for Enhancing Drug Bioavailability in Ocular Drug Delivery Systems
One of the major impediments to drug development is low aqueous solubility and thus poor bioavailability, which leads to insufficient clinical utility. Around 70–80% of drugs in the discovery pipeline are suffering from poor aqueous solubility and poor bioavailability, which is a major challenge…

Characterization of excipients to improve pharmaceutical properties of sirolimus in the…
Enhanced drug release and bioavailability of poorly soluble active pharmaceutical ingredient (API) can be achieved via a fluidized bed coating integrated with supercritical anti-solvent (SAS-FB) – a process of precipitating drug particles onto carrier granules. However, in the absence of excipients,…
