Three-dimensional printing is one of the fastest developing technology withinpharmaceutical field. With many advantages this method can be found as a new dosageform manufacturing technique, however low printing efficiency stays as one of the major limitations. Therefore, the preparation of filaments as a feedstock and printing of the final dosageforms in pharmacies may by the direction of development for this method. Thus, simple dosage and dissolution profile modification seems to be...

Over the last few decades, hot melt extrusion (HME) has emerged as a successful technology for a broad spectrum of applications in the pharmaceutical industry. As indicated by multiple publications and patents, HME is mainly used for the enhancement of solubility and bioavailability of poorly soluble drugs. This review is focused on the recent reports on the solubility enhancement via HME and provides an update for the manufacturing/scaling up aspects of melt extrusion. In addition, drug...

The aim of this study was to improve the pharmaceutical properties of theobromine (TB), particularly its flowability and dissolution rate, by preparing solid dispersions using different technologies (hot melt extrusion—HME, freeze-drying—FD, and supercritical fluid—SF) as well as testing different hydrophilic polymeric matrixes (Eudragit™ E, Plasdone™ S and Soluplus™)

Hot melt extrusion (HME) is considered an efficient technique in developing solid molecular dispersions, and has been demonstrated to provide sustained, modified and targeted drug delivery resulting in improved bioavailability. However, most commercial enteric or pH-responsive polymers are relatively difficult to process or have high Glass Transition Temperature (Tg) values, making their use with temperature-sensitive drugs, probiotics or biologics not viable. Shellac is a natural...

Electrospinning of Eudragit® FS 100 was investigated for the first time.
• Novel AC electrospinning produced excellent quality nano fibers at high throughput.
• Melt rheology of Eudragit® FS 100 was thoroughly explored.
• Eudragit® FS-based solid dispersions provided excellent control on release of poorly soluble spironolactone as pH varied.

Abstract The purpose of this study was to explore the feasibility of combining fused deposition modeling (FDM) 3D printing technology with hot melt extrusion (HME) to fabricate a novel controlled-release drug delivery device. Glipizide used in the treatment of diabetes was selected as model drug, and was successfully loaded into commercial polyvinyl alcohol(PVA) filaments by HME method. The drug-loaded filaments were printed through a dual-nozzle 3D printer, and finally formed a double-chamber...

Hot Melt Extrusion (HME) technology is a widely used for manufacturing process in the plastic and pharmaceutical industries and is an efficient and simple for the production of a solid dispersion. This technique is an environmental friendly, continuous process that does not use solvents. It is time and cost efficient and can be easily scaled up. In addition, HME may be used in conjunction with other technologies to effectively increase the solubility and dissolution rate of poorly water-soluble...

Abstract Objective: Fast melt tablets and sublingual route have been widely used for providing quick onset of action with the avoidance of first pass metabolism. The objective of this work was to compare the effect of different meltable binders namely; polyethylene glycol (PEG) 4000, pluronic F127 and pluronic F68 on the performance of fast release tablets of the model drug zolmitriptan prepared using the melt granulation technique regarding disintegration time (DT) and dissolution rate (DR) as...

Palonosetron HCl is a 5HT3 antagonist licensed for the prevention of acute chemotherapy-induced nausea and vomiting (CINV) associated with highly emetogenic chemotherapy agents (HEC) and the prevention of CINV associated with moderately emetogenic cancer chemotherapy (MEC). It has a substantially longer half-life (Approximately 40 h). So, it was plan to prepare melt in mouth tablet which could rapidly dissolved and absorbed which may produce rapid onset of action. Melt in mouth tablets were...
