Parenteral sustained release systems for proteins which provide therapeutic levels over a longer period avoiding frequent administration, which preserve protein stability during manufacturing, storage and application and which are biodegradable and highly biocompatible in the body are intensively sought after. The aim of this study was to generate and study mannitol core microparticles loaded with a monoclonal antibody IgG1 and coated with lipid either hard fat or glyceryl stearate at different...

Mini-tablets with diameters of 2.0, 2.5, and 3.0 mm are coated in two different lab-scale fluidized bed coaters equipped with a Wurster draft tube. The main focus of the research is to evaluate the inter-particle coating variability, and to assess the contribution of cycle time variation. Cycle times are measured using a photoluminescent tracer with a detector mounted on the top of the draft tube. The number of passes variability is represented from 5 to 28% of the total coating variability....

In the pharmaceutical tablet film coating process, we clarified that a difference in exhaust air relative humidity can be used to detect differences in process parameters values, the relative humidity of exhaust air was different under different atmospheric air humidity conditions even though all setting values of the manufacturing process parameters were the same, and the water content of tablets was correlated with the exhaust air relative humidity. Based on this experimental data, the...
