Could the Change of Excipient Content Improve the Stability of Gastroresistant Omeprazole Pellets?
Abstract
Omeprazole (OM), a temperature, pH, and moisture-sensitive drug, poses formulation challenges. This study delves into the complex development of OM pellets, focusing on the impact of buffering excipients on stability and release. Addressing the challenges of OM pellet stability requires a…

Towards the prediction of barrel fill level in twin-screw wet granulation
The barrel fill level is defined as the fraction of the free available volume for a given screw configuration that is occupied by the wet material and is an interplay of the material throughput, screw speed, screw setup, barrel length of the twin-screw granulator used and the properties of the…

Twin-screw melt granulation with PEG 8000: Effect of binder particle size and processing temperature…
Twin-screw melt granulation (TSMG) is one of the promising green technological approaches for the manufacturing of solid dosage forms of pharmaceuticals and nutraceuticals. PEG 8000 is one of the most popular TSMG binders. The effect of different low-melting grades of PEG on the TSMG granules’…

Functionality of wet-granulated disintegrant in comparison to directly incorporated disintegrant in…
Tablet disintegration is crucial for drug release and subsequent systemic absorption. Although factors affecting the disintegrant’s functionality have been extensively studied, the impact of wet granulation on the performance of disintegrants in a poorly water-soluble matrix has received much less…

Dwell Time on Tableting: Dwell Time According to Force versus Geometric Dwell Time
Dwell time is an important parameter responsible for the material deformation and the mechanical and biopharmaceutical properties of the tablet. Thus, it is widely used for scale-up purposes. The geometric dwell time (GDT) can be assumed based on the shape of the punch head and the diameter and…

Evaluation of Polyvinyl Alcohol as Binder during Continuous Twin Screw Wet Granulation
Binder selection is a crucial step in continuous twin-screw wet granulation (TSWG), as the material experiences a much shorter residence time (2–40 s) in the granulator barrel compared to batch-wise granulation processes. Polyvinyl alcohol (PVA) 4-88 was identified as an effective binder during…

Croscarmellose Sodium as Pelletization Aid in Extrusion-Spheronization
Only few excipients are known to be suitable as pelletization aids. In this study, the potential use of croscarmellose sodium (CCS) as pelletization aid was investigated. Furthermore, the impact of cations on extrusion-spheronization (ES) of CCS was studied and different grades of CCS were tested.…

Evaluation of binders in twin-screw wet granulation – Optimization of tabletability
Abstract
The influence of hydroxypropyl cellulose type (HPC-SSL SFP, HPC-SSL), concentration (2 %, 3.5 %, 5 %) and filler (lactose, calcium hydrogen phosphate (DCP)/microcrystalline cellulose (MCC)) on twin-screw wet granulation and subsequent tableting was studied. The aim was to identify the…

The effect of glidant on the tabletting behavior of common pharmaceutical excipients
Abstract
Glidant used for the purpose of powder flowability enhancement is well known within the pharmaceutical industry to improve tablet manufacturing. Despite the widespread use of glidant for this purpose, the effect of glidant on the effect of tableting behavior is not well studied. To address…
