Composite cryogels for dual drug delivery and enhanced mechanical properties.
(Wiley, 2018-04)In this study, we present a simple and effective process that integrates hydrogels with drugs + ceramics via physical crosslinks resulting in improved mechanical properties. These cryogels have the potential for controlled ... -
Faster release of lumen-loaded drugs than matrix-loaded equivalent in polylactic acid/halloysite nanotubes.
(MDPI, 2019-06-15)Nanocomposite-based drug delivery systems with intrinsic controlled release properties are of great interest in biomedical applications. We report a novel polylactic acid (PLA)/halloysite nanotube (HNT) nanocomposite-based ... -
Investigation of a novel freeze-thaw process for the production of drug delivery hydrogels
(Springer, 2005-12)Poly(vinyl alcohol) (PVA) is a water-soluble, biocompatible and biodegradable polymer, which has been widely applied in biomedical fields. In this paper, novel physically cross-linked hydrogels composed of PVA and comprising ... -
Investigation of the effects of orientation on freeze/thawed Polyvinyl alcohol hydrogel properties.
(Elsevier, 2018-12)Although hydrogels produced via freeze-thawing (F/T) technique have been thoroughly studied in literature, stretching hydrogels in between freeze-thawing cycles could change its properties and might be modulated for drug ... -
Micro-injection moulding of poly(vinylpyrrolidone-vinyl acetate) binary and ternary amorphous solid dispersions.
(MDPI, 2019-05)Micro-injection moulding (µIM) was used for the production of enteric tablets of plasticised and unplasticised solid dispersions of poly(vinylpyrrolidone-vinyl acetate) (PVPVA), and the effect of the mechanical and thermal ... -
Novel polyvinyl-alcohol microsphere for everolimus delivery for subependymal cell astrocytoma
(Elsevier, 2023-02-02)Everolimus (EVR) has demonstrated efficacy in treating subependymal giant cell astrocytoma (SEGA) and other tuberous sclerosis (TSC) manifestations. Oral use of EVR is associated with low bioavailability and systemic toxicities ... -
Preparation of a novel freeze thawed poly (vinly alcohol) composite hydrogel for drug delivery applications
(Elsevier, 2007-09)Poly(vinyl alcohol) (PVA) is a water-soluble, biocompatible and biodegradable polymer, which has been widely applied in biomedical fields. In this paper, novel physically cross-linked hydrogels composed of PVA and comprising ... -
Processing stability and the significance of variation in extrusion speeds and temperture on SSB® 55 Pharma Grade Shellac for Oral Drug Delivery
(MDPI, 2017-09-06)The melt-extrusion process is utilized in the pharmaceutical arena for the manufacturing of a variety of dosage forms and formulations, including solid dispersions. This technology is considered an efficient and continuous ... -
The production of a novel poly(vinyl alcohol) hydrogel cryogenic spheres for immediate release using a droplet system.
(IOP Science, 2019-06-05)Although freeze-thaw mechanism for producing crosslinked hydrogels is relatively easy and simple, it lacks sufficient integrity and support leading to modifications on its three-dimensional polymeric network arrangement ... -
Synthesis and characterisation of novel temperature and pH sensitive physically crosslinked poly(N-vinylcaprolactam-co-itaconic acid) hydrogels for drug delivery.
(MDPI, 2019-08-29)Previous studies involving poly N-vinylcaprolactam (PNVCL) and itaconic acid (IA) have synthesised the hydrogels with the presence of a solvent and a crosslinker, producing chemically crosslinked hydrogel systems. In this ...
