ABSTRACT:
An immediate release compressed pharmaceutical tablet that has two or more segments and a top and a bottom and has a height that exceeds the width of the tablet. The height is measured vertically from the top to the bottom of the tablet while it is in the tablet die in which it is fully compressed, after compression has been completed. The width is measured as the greatest horizontal dimension of the tablet at a location halfway between the top and the bottom of the tablet, except that when the horizontal cross-section of the tablet is substantially rectangular, the width is defined by locating the two shorter sides of the perimeter of the horizontal cross-section, and measuring the length of a line that is at right angle to the shorter sides.
