The invention concerns multilayer microspheres containing an acid substance, a basic substance and a water-soluble isolating agent which when it dissolves in water, after almost instant effervescence, brings about a homogeneous dispersion of the active principle. The invention also concerns a method for preparing such microspheres by rotational granulation on a fluid air bed associated with a system of tangential spraying of the wetting liquid.
