Mechanofusion is a dry coating method that can be used to improve the flowability of cohesive powder by coating host particles with a lubricant, for example magnesium stearate (MgSt). It has been shown previously that fragmenting material can under some circumstances be mechanofused with MgSt without impairing compactibility of the powder and without reducing the dissolution rate of the resulting tablets.

This study investigates the effects of a variety of coating materials on the flowability and dissolution of dry-coated cohesive ibuprofen powders, with the ultimate aim to use these in oral dosage forms. A mechanofusion approach was employed to apply a 1% (w/w) dry coating onto ibuprofen powder with coating materials including magnesium stearate (MgSt), l-leucine, sodium stearyl fumarate (SSF) and silica-R972.
