Abstract:

Nanomilling process which reduces the particle size of active pharmaceutical ingredient (API) down to the sub-micron range is a popular technique in the pharmaceutical field for the delivery of poorly water soluble drugs. This is a potential technique to achieve better in vitro dissolution and high in vivo exposure1. This presentation will highlight: a) Basic principles of Nanomilling technology b) Selection criteria of this technology during preclinical stage c) Formulation design during Clinical development d) Design of process parameters using Factorial design and MVDA approach2. e) Techniques for improving the stability of the system f) Analytical characterization methods g) Case studies showing improvement of Bioavailability using Nanoparticulate formulation.
