Summary for Patent: 4,735,805
Title:Bisectable drug tablet
Abstract:A bisectable drug tablet having an elongated tablet body with a length greater than its width. The tablet body also has top and bottom surfaces with a concavity being provided in each thereof. A breaking groove is formed in at least one of the concavities and extends laterally across the width of the tablet at an apex of the one cavity. Thus, upon application of a downward pressure to either the top or bottom surfaces of the tablet, when the other of the top and bottom surfaces faces downwardly and the opposite longitudinal ends of the tablet rest on a support surface, the tablet will fracture along the groove, the fracture occurring irrespective of whether the breaking groove faces toward or away from the support surface.
