    • A tri-scored drug tablet (10) having an elongated tablet body (11) with a length greater than its width. The body (11) has a bottom facing surface with a pair of concavities (23, 24) therein. Each concavity (23, 24) is equal in size and has parallel major and minor axes, each concavity (23, 24) further having a smooth and uninterrupted arcuate surface extending between the opposite longitudinal ends of said body (11) and a longitudinally central part of said tablet (10). The opposite longitudinal ends of the body (11) and the longitudinally central part are of a thicker dimension than the thickness of the body (11) measured at an apex of each of the concavities (23, 24). Aligned breaking grooves (21, 29, 31, 32) are formed in the top and bottom surfaces at both of the concavities (23, 24) and between the concavities (23, 24) at said longitudinally central part, each of breaking groove (21, 29, 31, 32) extending laterally across the width of said tablet (10) at said apex of each of said concavities (23, 24) at said longitudinally central part to divide the tablet (10) into four quarter sections (48, 49, 51, 52) of equal size.
    • 具有长度大于其宽度的细长片剂本体(11)的三片药片(10)。 主体(11)具有底面朝向的表面,其中具有一对凹部(23,24)。 每个凹部(23,24)的尺寸相等并且具有平行的主轴和短轴,每个凹部(23,24)还具有在所述主体(11)的相对的纵向端部之间延伸的平滑且不间断的弓形表面,并且纵向中心 所述片剂(10)的一部分。 主体(11)和纵向中心部分的相对的纵向端部具有比在每个凹部(23,24)的顶点处测量的主体(11)的厚度更大的尺寸。 在两个凹部(23,24)的顶表面和底表面以及在所述纵向中心部分处的凹部(23,24)之间形成有分隔开的凹槽(21,29,31,32),每个断裂槽 在所述纵向中心部分处,在每个所述凹部(23,24)的顶点处横向延伸穿过所述片剂(10)的宽度的横截面(21,29,31,32),以将片剂(10)分成四个四分之一部分 ,49,51,52)。
