ABSTRACT:
The invention relates to a method by which it is possible to prepare a formulation consisting of thickening or suspending agents and other excipients, having the property of dispersing and dissolving quickly in water or aqueous vehicles, without clot formation, with which it is possible to prepare an extermoraneous homogeneous suspension of solid particles and more particularly of micro-encapsulated drugs, which otherwise have the tendency to precipitate or float.
