RDD Europe 2017
Ddry powder carrier-based formulation of a model active pharmaceutical ingredient (API), which includes coarse and fine lactose grades, is in development.
The initial development work was conducted at a small scale low-shear mixer in order to demonstrate proof of concept. A scale-up of the blending process was necessary to support clinical trials.
This work focuses on the blending process scale-up and optimization, which was performed according to a design of experiments (DOE) approach considering the following variables:
- particle size distribution (PSD) of the micronized API,
- blending time per step and
- API concentration.
