Abstract: The invention relates to a method of preparing a composition of lipid particles comprising a bioactive protein, capable of being subjected to high shear forces without substantial loss of activity, and a lipid agent. The characterizing features of the method are the introduction of a protein preparation and a lipid agent to a homogenization station, whereupon the resulting fluid mixture of protein an lipid agent is subjected to high pressure homogenization. The so formed lipid particles are collected and if necessary further processed into a pharmaceutical formulation.
