Overview of milling techniques for improving the ...

Jul 01, 2015· Ball milling of pure drug mixtures have also been investigated. More recently, ball milling of a combination of two BCS Class II drugs, simvastatin and glipizide, resulted in the formation of stable co-amorphous mixtures . Despite the efficiency of ball milling for size reduction or amorphization, it is less amendable to scale up.
