ABSTRACT:
A tri-scored drug tablet having an elongated tablet body with a length greater than its width. The body has a bottom facing surface with a pair of concavities therein. Each concavity is equal in size and has parallel major and minor axes, each concavity further having a smooth and uninterrupted arcuate surface extending between the opposite longitudinal ends of said body and a longitudinally central part of said tablet. The opposite longitudinal ends of the body and the longitudinally central part are of a thicker dimension than the thickness of the body measured at an apex of each of the concavities. Aligned breaking grooves are formed in the top and bottom surfaces at both of the concavities and between the concavities at said longitudinally central part, each of breaking groove extending laterally across the width of said tablet at said apex of each of said concavities and at said longitudinally central part to divide the tablet into four quarter sections of equal size.
