Exploring the effect of intramuscularly injected polymer/lipid hybrid nanoparticles loaded with…
The current study intended to develop a new treatment of schizophrenia having a sustained release activity. Quetiapine fumarate (QF)-loaded polymer/lipid hybrid nanoparticulate systems of polycaprolactone (PCL) and Geleol™ were fabricated using polyvinyl alcohol (3% w/v). The proposed hybrid systems…

Development and in vivo validation of phospholipid-based depots for the sustained release of…
By direct deposition of the drug at the local site of action, injectable depot formulations – intended for treatment of a local disease or for local intervention – are designed to limit the immediate exposure of the active principle at a systemic level and to reduce the frequency of administration.…

Sustained and targeted delivery of hydrophilic drug compounds: A review of existing and novel…
The sustained and/or targeted delivery of hydrophilic drugs is an important field within drug delivery, presenting unique challenges when compared to that of hydrophobic drugs. Yet relatively few comprehensive reviews specific to hydrophilic drug delivery have been published recently. In this…

Patient-specific in vitro drug release testing coupled with in silico PBPK modeling to forecast the…
Biorelevant in vitro release models are valuable analytical tools for oral drug development but often tailored to gastrointestinal conditions in ‘average’ healthy adults. However, predicting in vivo performance in individual patients whose gastrointestinal conditions do not match those of healthy…

Encapsulation of polyphenols in pH-responsive micelles self-assembled from octenyl-succinylated…
An amphiphilic polymer based on octenyl succinic anhydride-modified curdlan oligosaccharide (MCOS) was synthesized. The critical micelle concentration of MCOS was 3.91 μg·mL−1. MCOS could self-assemble into spherical micelles with a particle size of 230.1 nm and a zeta potential of − 37.9 mV. When…

3D printing of bioactive materials for drug delivery applications
Introduction
Three-dimensional (3D) printing, also known as additive manufacturing (AM), is a modern technique/technology, which makes it possible to construct 3D objects from computer-aided design (CAD) digital models. This technology can be used in the progress of drug delivery systems, where…

Cyclodextrin superstructures for drug delivery
Cyclodextrins, typically known for their molecular encapsulation properties to form inclusion complexes with guests of adequate size and hydrophobicity, have recently been explored in tridimensional supramolecular assemblies. These structures have additional advantages over inclusion complexes: they…

Silicon Oxycarbide Porous Particles and Film Coating as Strategies for Tenofovir Controlled Release…
Sustained release of antiretroviral drugs is currently the most encouraging strategy for the prevention of the sexual transmission of HIV. Vaginal tablets based on hydrophilic gelling polymers are an interesting dosage form for this purpose, since they can be developed to modify the release of the…
