Abstract: The invention concerns the formulation and method of fabricating rapid dispersion spheroids which can be heavily charged with active substances. These spheroids are formulated using at least one active substance, specifically a solution of vegetable origin, absorbed and/or adsorbed on a dry technological mixture with a slightly substituted hydroxypropylated cellulose ether base at the level of core groups &bgr;-O-glucopyranosil, preferably characterized by having a substitution rate of about 11% and a water soluble fractional percentage of about 4.29%. The spheroids are obtained by an extrusion and spheronization process. This invention is of interest in the fields of health, hygiene, dietetics, cosmetology, nutrition, and agriculture; it may concern humans or animals.
