Abstract
A pharmaceutical pellet is disclosed, comprising a spherical core containing active ingredient with a smooth surface and a coating on the core which controls the release of the active ingredient in a pH-independent manner. With such a pellet the release of the active ingredient can follow a profile with a lag phase of 60 minutes to 840 minutes, a proportion of 5 wt. % or less of the active ingredient being released during the lag phase. The active ingredient can furthermore be released from the pellet with a profile such that after the lag phase the release of the active ingredient amounts to between 3 and 25 wt. % per hour.
