Experimental Studies & Analyses of

Granule Microstructure 

Here, we are working to understand the effect of granulation process parameters on granule content uniformity and dissolution and its subsequent effect on tablet properties (microstructure and dissolution).  We are aiming to decouple the effects of segregation, preferential wetting and drug migration to be able to design and engineer optimal granules to influence and obtain quality tablets with desired properties.
