Hot-melt extrusion

YOUR FORMULATION CHALLENGE - IOI Oleo SOLUTIONS According to the Biopharmaceutical Classification System (BCS), more than 70% of the APIs used in pharmaceutical preparations are difficult to formulate due to poor solubility and/or permeabilities, and the majority of drug candidates have…

The downstream processing of hot-melt extruded amorphous solid dispersions (ASDs) into tablets is challenging due to the low tabletability of milled ASDs. Typically, the extrudate strand is sized before milling, as the strand cannot be fed directly into the milling system. At the lab scale, the…

Telemedicine is defined as the delivery of healthcare services at a distance using electronic means. The incorporation of 3D printing in the telemedicine cycle could result in pharmacists designing and manufacturing personalised medicines based on the electronic prescription received. Even with the…
