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...

Hot-melt extrusion is well established in the plastics industry and is applied in pharmaceutical application for more than 30 years. In contrast to plastics, pharmaceutical formulation development is more complex as each formulation is unique in terms of compositions of active pharmaceutical ingredients, carrier and additives. Therefore, new innovative solutions are demanded to tackle the pharma specific challenges in formulation development like how to prevent losses with expensive material...

Orodispersible films (ODFs) are an advantageous dosage form to accomplish patient convenience and compliance in oral drug delivery. They provide a number of special application features, such as the ease of administration without water and suitability for patients with swallowing problems. However, this promising dosage form has been limited to immediate release formulations so far. The aim of this study was to develop a thin film produced by solvent casting, which is rapidly disintegrating...

The objectives of this study were to explore sodium dodecyl sulfate (SDS) and Soluplus on the crystallization inhibition and dissolution of felodipine (FLDP) extrudates by bottom-up and top-down approaches. FLDP extrudates with Soluplus and/or SDS were prepared by hot melt extrusion (HME), and characterized by PLM, DSC and FT-IR. Results indicated that Soluplus inhibited FLDP crystallization and the whole amorphous solid dispersions (ASDs) were binary FLDP-Soluplus (1:3) and ternary...

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...

Many future drug products will be based on innovative manufacturing solutions, which will increase the need for a thorough understanding of the interplay between drug material properties and processability. In this study, hot melt extrusion of a drug-drug mixture with minimal amount of polymeric excipient was investigated.
