Abstract

Bull's-eye tablets in which both the shaped body per se and the lands surrounding the bull's-eye are mechanically stable and even lend themselves to production in modern high-throughput tablet presses and in which the core placed in the larger shaped body is joined to the tablet in a stable manner and does not separate from the tablet matrix during production, packaging, transportation and handling can be obtained if the contour line of the core falls from the edge zone to the lowest point and climbs back to the edge zone.
