Abstract Amorphous solid dispersions layered pellets solve a problem of poorly water soluble drugs. Speaking about oral drug formulations, drug carrier solutions based on starter cores are suitable for several drug classes and open new opportunities for modified drug release profiles. Layering and coating techniques, such as Wurster fluid bed process at different batch sizes, […]
Abstract Cellets are inert starter cores made of microcrystalline cellulose (MCC). They play an important role in new formulations of solid dosage forms. As a carrier system for actives, the chemical inertness and surface smoothness are crucial parameters. Additionally, high level of robustness and sphericity simplify formulations and technical processes, such as fluidized bed technologies […]
The renaissance of micropellets is promoting innovative technologies In recent years, formulations based on pellets and micropellets have been the trend. New technologies make it possible to circumvent property rights for active ingredients and are therefore very popular with pharmaceutical customers. But which technologies are the most important? Pellets are the jack-of-alltrades of solid dosage […]
Abstract Microcrystalline cellulose pellets (MCC) and sugar are well-known materials in pellet technology. Pellet technology describes the drug load onto starter pellets for controlled release formulations by Wurster process or others. Inert pellets are made of microcrystalline cellulose, while water soluble pellets are composed of sugar. Both material classes show desirable characteristics, such as a […]
Abstract Microcrystalline Cellulose (MCC) pellets represent a chemically inert class of active pharmaceutical ingredients (API) carriers. A narrow particle size distribution (PSD) maximizes control over content uniformity. In this case study, we will focus on measuring the particle size distribution and on sphericity. Pellets for oral drug forms MCC pellets are used as starter beads […]
Abstract Several drug substances are known to be extremely bitter. In special for paediatric and geriatric applications, costumer compliance by means of taste acceptance is a highly sensitive topic. Taste masking is therefore an important issue in pharmaceutical industry of oral dosage forms not only to improve the compliance, but it is also used to […]
Abstract Starter beads such as pellets made of microcrystalline cellulose (MCC) are frequently used in the formulation of oral drug delivery systems, e.g. multiparticulates [1] or multi-unit pellet system (MUPS) tablets [2]. Certain properties are requested to MCC pellets. We shed some light on sphericity size and friability in this note. Starter beads for MUPS […]
Abstract Theophylline is a powerful active used for the acute treatment of respiratory distress. Its bioavailability and uptake rates are high. Drug carrier systems are pellets made of sugar or microcrystalline cellulose (MCC). This case study will point on the specific advantages of MCC pellets. Layering on starter pellets Basically, theophylline is an alkaloid that […]
