What this patent protects

This patent protects a tablet formulation of a pharmaceutical product, specifically designed to prevent tablets from sticking together during film-coating.

USPTO Abstract

The present invention can retain the volume of a tablet large without increasing the thickness of the tablet or the like dimension and prevents a plurality of tablets from sticking to each other even if they are subjected to a film-coating or the like treatment, so as to improve the yield. The tablet is a tablet ( 1 ) longer in one direction when seen in plan. The tablet ( 1 ) has side edges ( 6 ) each of which extends in a longitudinal direction and is formed in the shape of a curve projecting outwardly in plan view. The curve has a radius of curvature (R 1 ) set to at least 1.5 times a length (L) of the tablet. This makes a projected area of the tablet ( 1 ) in plan view at least 97% with respect to a projected area of a standard elliptical tablet having opposite end portions each of which is formed by a semi-circle having a diameter of a width (W) of the tablet.
