Pellet
Preparation, characterization, and in vitro release of microencapsulated essential oil…
Oregano essential oil (EO)–loaded pellets were prepared using calcium phosphate substrates of different specific surface areas (Sw) and as binders EO in water emulsions with low or high EO content, stabilized with polysaccharides (PSC) or a combination of PSC-Eudragit® L100-55 (PSC-PLM)…

The impact of applying an additional polymer coating on high drug-loaded amorphous solid dispersions…
Inhibiting surface crystallization is an interesting strategy to enhance the physical stability of amorphous solid dispersions (ASDs), still preserving high drug loads. The aim of this study was to investigate the potential surface crystallization inhibitory effect of an additional polymer coating…

In Situ Co-Amorphization of Olanzapine in the Matrix and on the Coat of Pellets
In situ amorphization is a promising approach, considered in the present work, to enhance the solubility and dissolution rate of olanzapine, while minimizing the exposure of the amorphous material to the stress conditions applied during conventional processing. The production of pellets by…

Development and Evaluation of Novel Multi-unit Pellet System Formulation of Metoprolol Succinate for…
Abstract
Metaprolol succinate is a highly water-soluble drug with extensive first-pass metabolism. It needs to be administered about 3-4 times a day for optimum therapeutic effect. Conventional extended-release formulations are available but have their own disadvantages. The study was to designed…

Solventless amorphization and pelletization using a high shear granulator. Part II; Preparation of…
The aim of this study was to investigate the preparation of co-amorphous mixture-layered pellets using solventless pelletization and amorphization using a high shear granulator (as suggested in the first part of this study) by high shear mixing of drug crystals and a crystalline co-former with…

Solventless amorphization and pelletization using a high shear granulator. Part I; feasibility study…
The aim of the current study was to investigate the feasibility of solventless amorphization and pelletization using a high shear granulator, to produce amorphous drug-layered pellets by simply mixing drug crystals and inactive spheres without using solvent and heating. Indomethacin crystals were…

Compression Density as an Alternative to Identify an Optimal Moisture Content for High Shear Wet…
Pellet production is a multi-step manufacturing process comprising granulation, extrusion and spheronisation. The first step represents a critical control point, since the quality of the granule mass highly influences subsequent process steps and, consequently, the quality of final pellets. The most…

Continuous Processing of Micropellets via Hot-Melt Extrusion
Microparticulate drug delivery systems, e.g., micropellets (MPs), are used in a variety of pharmaceutical formulations such as suspensions, injectable systems, and capsules. MPs are currently manufactured mainly via batch, solvent-based processes, e.g., spray-drying and solvent…

Hydrodynamic behaviour of Cellets™ (Ph.Eur./USP) in a spouted bed using image processing method
The hydrodynamic behaviour of the spouted bed in the pharmaceutical industries has been found to be less addressed. The present paper has focused on the hydrodynamic characteristics of a spouted bed where the Cellets™ (Ph.Eur./USP) is adopted as the bed material. Experiments are carried out with…
