Abstract This application note is based on content from Pohlen et al. [1]. Simvastatin (CAS number 79902-63-9) is a cholesterol-lowering agent with a low bioavailability of 5% [2,3]. This API is formulated as a lipid based drug delivery system for oral uptake. Two technologies, which are spray drying and fluidized bed layering technologies were compared […]
Abstract Multidimensional Correlation of Surface Smoothness and Process Conditions is a necessary attempt to better understand, optimize and outperform process steps of drug formulations. Particle coating and layering in a fluidized bed process is a main attempt in pharmaceutical industry for drug production for modern oral dosage forms. The precise knowledge of control process parameters […]
Abstract Patients with dysphagia may have obstacles to swallow tablets or large multiparticulates. The former dosage form can even not be crushed in case that the tablet exhibits a modified release or taste-masking profile through outer layering. As a solution, so called jelly formulations may be a valuable attempt. Jellies are delivery vehicles incorporating sustained […]
Abstract Modified drug release formulations for suspensions are a perfect solution for children and patients with swallowing difficulties. In many cases, these formulations are based on pellets serving as starter beads. In this report, an attempt on microparticle coating by Mohylyuk et al. [1] is described. Herein, small scaled microcrystalline cellulose pellets (Cellets® 90 and […]
Abstract Coating uniformity is a critical parameter in coating processes in novel pharmaceutical formulations. Speaking about pellet technology, coating and layering are the main methods for implementing drug functionalities, such as modified release of the active, taste-masking properties and further more. Coating uniformity guaranties not only upholding functionalities of the formulation, but also prevent risks […]
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 […]
