New universal carrier ink for 3D printing
Researchers at ETH have produced a gel from cellulose fibres and biodegradable nanoparticles that liquifies when pressed through the nozzle of a 3D printer, but then quickly returns to its original shape. Their invention paves the way for personalised biomaterial implants.
Essentially, 3D…

Spray-Dried Amorphous Solid Dispersions of Griseofulvin in HPC/Soluplus/SDS: Elucidating the…
This study aimed to elucidate the impact of a common anionic surfactant, sodium dodecyl sulfate (SDS), along with hydroxypropyl cellulose (HPC) and Soluplus (Sol) on the release of griseofulvin (GF), a poorly soluble drug, from amorphous solid dispersions (ASDs). Solutions of 2.5% GF and 2.5%–12.5%…

Mechanistic understanding regarding the functionality of microcrystalline cellulose and powdered…
Powdered cellulose (PC) and microcrystalline cellulose (MCC) show considerable different behavior during wet-extrusion and spheronization. While MCC is an appropriate pelletization aid, PC is not suitable. The differences were explained by either the “molecular-sponge” or the “crystallite-gel”…

Polymers for Extrusion‐Based 3D Printing of Pharmaceuticals: A Holistic Materials–Process…
Three dimensional (3D) printing as an advanced manufacturing technology is progressing to be established in the pharmaceutical industry to overcome the traditional manufacturing regime of ʹone size fits for allʹ. Using 3D printing, it is possible to design and develop complex dosage forms that can…

Quantification of porogen effect on the drug release from single- and multi-layered ethylcellulose…
The aim of this work was to develop a mathematical model to estimate the drug release from a conventional single-compartment reservoir pellet and extend its applicability to multi-compartment reservoir pellets. Conventional pellets were prepared by layering the drug onto starter-core then applying…

Dissolution Advantage of Nitazoxanide Cocrystals in the Presence of Cellulosic Polymers
The effect of hydroxypropyl methylcellulose (HPMC) and methylcellulose (Methocel® 60 HG) on the dissolution behavior of two cocrystals derived from nitazoxanide (NTZ), viz., nitazoxanide-glutaric acid (NTZ-GLU, 1:1) and nitazoxanide-succinic acid (NTZ-SUC, 2:1), was explored.
Powder dissolution…

Scale-up of electrospinning technology: Applications in the pharmaceutical industry
Electrospinning (ES) was originally reported in 1899 and the technology has been used since for the fabrication of con- tinuous fibers (Cooley, 1899).
Beginning from the 1980s and particularly during the recent decade, the technology has gained increasing attention. Possibly this can be…

Fibrillated Cellulose via High Pressure Homogenization: Analysis and Application for Orodispersible…
Powdered cellulose (PC) and microcrystalline cellulose (MCC) are common excipients in pharmaceuticals.
Recent investigations imply that particle size is the most critical parameter for the different performance in many processes. High-pressure homogenization (HPH) was used to reduce fiber size of…
