    Generally milling may be conducted with the drug in its dry state (dry milling) or suspended in a liquid medium (wet milling). In dry milling the mechanical energy imparted fosters drug-excipient interactions via van der Waals forces or hydrogen bonding. The resultant drug-excipient composite particles are often stable exhibit low tendencies to agglomerate and retain the activated status of
