Trial F15 and F16 showed highest fines generation however, it has no effect on pellet surface.

The X 3 had very less impact of Y 3 which is not covered in equation. Pareto chart showing RPN scores for the coating process parameters for pantoprazole enteric coated pellets before and after risk mitigation.

The results table 4 showed that the percentage fines generation varied from 0. The aim of this work was to optimize process variables for enteric coated pellets processing. X 2 and X 3 were the most critical process parameters found affecting on yielded and assay of pellets while X 3 has less impact.

Effect of matrix forming polymer concentration was evaluated based on pellet size, shape, morphology, drug content and dissolution profile. Performance improvement through proactive risk assessment: The coating process variables studied were air volume X 11.1 rate X 2 and atomization air pressure X 3versus percentage fines Y 1percentage agglomerates Y 2 and assay Y 3 as responses.


Loss on drying LOD Accurately weighed pellets 1. The RPN must be calculated for each cause of failure.

Formulating extended release drug pellets using CPS tec

The aim of this work was to decide the ranges gpfg CPPs involved in enteric coating process. The development of the product is normally done in 6″ Wurster with the batch size 0. Formulation and process considerations. Air volume below 45 cfm, pellets didn’t fluidize properly and above gcpg cfm pellets impacting on the filter wall and less time spend in Wurster column.

Maronga SJ, Wnukowski P. The comparative SEM images of enteric coated pellets of optimized process parameters run at lab and scale up presented in fig. Multiparticulate Oral Drug Delivery.

Nowadays USFDA also demanding for a scientific approach for scale activity based on development batches.

Response surface plot showing the influence of process variables gpcb -a fines, b agglomerates, and c assay Assay was significantly influenced by the linear models of spray rate X 2. However, lower correlation coefficients were obtained for fines 0.

Tpcg and characterization of controlled release pellets coated with an experimental latex: Following completion of process development studies, a greater understanding of the risks to product yield and assay associated with coating process been developed in DS which covered all validated range of process variables.


The acceptable range of material attributes was determined based on DS. Combined population balance and thermodynamic modeling of the batch top-spray fluidized bed coating process.

The optimization performed to decide level of X 2 and X 3 for fines and agglomerated free process. Christensen FN, Bertelson P.

Optimized process variables s et al. Nevertheless, once the effect of variables are studied and understood in lab model, it will make the analysis much easier. In this study pantoprazole enteric coated pellets used to prepare oro dispersible multiunit particulate system MUPS tablet of pantoprazole where enteric coating was a functional coating which decided the acid resistance capacity of pellets.

Int J Pharm ; Just like the variables remaining same in pilot scale also, the same process control will apply.

Dissolution in acidic condition, i. Linear scale-up from lab scale to pilot scale assumed that the occupancy was the same and the distribution plate in each piece of equipment is geometrically similar.

Atomization Air Pressure bar 0.
