Abstract

Solid, elongate dosage forms (10) with a long axis (11) and with a length (L) which is defined by projection of the ends (12, 13) of the dosage form to the long axis, where a cross-sectional area (14, 15, 16) oriented perpendicular to the long axis (11) has an area which is variable along the long axis (11) and increases from a cross-sectional area (15) which is located between the ends (12, 13) and has a minimal area essentially continuously toward the two ends (12, 13) up to in each case a cross-sectional area (14 and 16 respectively) with a maximal area, wherein the distance of the maximal cross-sectional area (14) which is located near one end (12) from the maximal cross-sectional area (16) which is located near the other end (13) is, projected on the long axis (11), more than half the length (L) of the dosage form (10), are described.
