   09 Jun 2023 | Contributor(s):: Rao, Rajat Radhakrishna, Pandey, Abhijeet, Hegde, Aswathi R., Kulkarni, Vijay Induvadan, Chincholi, Chetan, Rao, Vinay, Bhushan, Indu, Mutalik, Srinivas

   In order to be at pace with the market requirements of solid dosage forms and regulatory standards, a transformation towards systematic processing using continuous manufacturing (CM) and automated model-based control is being thought through for its fundamental advantages over conventional batch...

2. Inline UV/Vis spectroscopy as PAT tool for hot-melt extrusion

   In the framework of Quality-by-Design (QbD), the inline determination of process parameters or quality attributes of a product using sufficient process analytical technology (PAT) is a center piece for the establishment of continuous processes as a standard pharmaceutical technology. In this...

4. Foam granulation: new developments in pharmaceutical solid oral dosage forms using twin screw extrusion machinery

   09 Jun 2023 | Contributor(s):: Thompson, M. R., Weatherley, S., Pukadyil, R. N., Sheskey, P. J.

   This paper investigates foam granulation in a twin screw extruder as a new continuous wet granulation technique for pharmaceutical powder drug formulations. Foamed aqueous binder has a reportedly lower soak-to-spread ratio than drop or spray liquid addition in batch granulation. This work...

5. Control of Pharmaceutical Cocrystal Polymorphism on Various Scales by Mechanochemistry: Transfer from the Laboratory Batch to the Large-Scale Extrusion Processing

   09 Jun 2023 | Contributor(s):: Stolar, T, Lukin, STireli, M, Sovic, I, Karadeniz, B, Kerekovic, I, Matijasic, G, Gretic, M, Katancic, Z, Dejanovic, I, di, Michiel, M, Halasz, I, Uzarevic, K

   We demonstrate a controllable mechanochemical synthesis of cocrystal polymorphs of ascorbic acid (vitamin C) and nicotinamide (vitamin B3) on different scales and without using bulk solvents. Next to the previously described polymorph of the 1:1 cocrystal, which is one of the first cocrystals...
