Rapidly disintegrating low friability tablets comprising silica materials

This invention pertains to the ability to provide rapidly disintegrating tablets through the inclusion of a silica material in combination with other common tablet components. Such a silica material must exhibit a sufficiently low surface area in order to boost the ability of the table to separate quickly when introduced into a user's mouth cavity. Such a tablet is dimensionally stable prior to use (low friability) and, when immersed in water the tablet disintegrates therein in less than about 60 seconds.
