Hot Melt Extrusion, a production process that has been around for quite some time, has the ability to produce innovative compounds not previously achievable with conventional methods. However, many variables need to be considered prior to production. The use of small-scale extruders and 3D printers provides compounders a pathway for developing new dosage forms at a minimal cost while initial research is being completed. This article discusses the uses of Hot Melt Extrusion, the equipment used, the current and future applications, and the challenges with the technology.

: Chagas disease is a neglected tropical disease caused by infection with the parasite . Benznidazole and nifurtimox are the only approved drugs for treating this condition, but their low aqueous solubility may lead to erratic bioavailability. This work aimed for the first time to formulate tablets of nifurtimox by hot melt extrusion coupled with 3D printing as a strategy to increase drug dissolution and the production of tablets with dosage on demand.

Curcumin and hesperetin are plant polyphenols known for their poor solubility. To address this limitation, we prepared amorphous PVP K30-phosphatidylcholine dispersions via hot-melt extrusion. This study aimed to evaluate the effects of the amounts of active ingredients and phosphatidylcholine, as well as the process temperature, on the performance of the dispersions.

In recent years, with the increasing patient population, the need for complex and patient-centric medications has increased enormously. Traditional manufacturing techniques such as direct blending, high shear granulation, and dry granulation can be used to develop simple solid oral medications. However, it is well known that "one size fits all" is not true for pharmaceutical medicines.

As reported during the last five years, SnSe is one of the leading thermoelectric (TE) materials with a very low lattice thermal conductivity. However, its elements are not as heavy as those of classical thermoelectric materials like PbTe or BiTe. Its outstanding TE properties were revealed after repeated purification steps to minimize the amount of oxygen contamination, followed by spark plasma sintering.
