Abstract
A process is described for the activation (increase in solubility and bioavailability) of drugs. The process, carried out in a vibrational mill, is characterised by the use of given proportions between the physical mixture made up of drug and pharmaceutical carrier and the empty volume among the grinding means contained inside the mill. The process leads to obtaining powders for pharmaceutical use in which the drug has a high and constant degree of activation; this result is obtainable irrespective of the nature of the drug and carrier used, and of their weight ratio.
