Process optimization for continuous extrusion wet granulation
Contributor(s):: Tan, L, Carella, AJ, Ren, YK, Lo, JB
Three granulating binders in high drug-load acetaminophen blends were evaluated using high shear granulation and extrusion granulation. A polymethacrylate binder enhanced tablet tensile strength with rapid disintegration in simulated gastric fluid, whereas polyvinylpyrrolidone and hydroxypropyl...

Native starch as in situ binder for continuous twin screw wet granulation
Contributor(s):: Vandevivere, Lise, Portier, Christoph, Vanhoorne, Valerie, Hausler, Olaf, Simon, Denis, De Beer, Thomas, Vervaet, Chris
The use of native starch as in situ binder in a continuous twin screw wet granulation process was studied. Gelatinization of pea starch occurred in the barrel of the granulator using a poorly soluble excipient (anhydrous dicalcium phosphate), but the degree of gelatinization depended on the...

Exploratory studies in heat-assisted continuous twin-screw dry granulation: A novel alternative technique to conventional dry granulation
Contributor(s):: Kallakunta, Venkata Raman, Patil, Hemlata, Tiwari, Roshan, Ye, Xingyou, Upadhye, Sampada, Vladyka, Ronald S., Sarabu, Sandeep, Kim, Dong Wuk, Bandari, Suresh, Repka, Michael A.
Dry granulation is the preferred technique for solvent-sensitive products, especially drugs with stability problems such as hydrolysis. Twin-screw granulation is a continuous granulation technique, offering a potential alternative to conventional dry granulation techniques such as roller...

Effect of formulation and process variables on lipid based sustained release tablets via continuous twin screw granulation: A comparative study
Contributor(s):: Kallakunta, Venkata Raman, Tiwari, Roshan, Sarabu, Sandeep, Bandari, Suresh, Repka, Michael A.
The current study's aim is to prepare lipid based sustained release tablets via a twin-screw granulation technique and compare those dosage forms with conventional techniques, namely wet granulation and direct compression. The granules were successfully manufactured in a single-step, continuous...
