Abstract: A controlled absorption diltiazem pellet formulation for oral administration comprises a core having diltiazem or a pharmaceutically acceptable salt thereof as the active ingredient. The core is surrounded by a coating which has only a single layer which is comprised of a relatively major proportion of talc and relatively minor proportion of sodium lauryl sulfate admixed with a minor proportion of a pharmaceutically acceptable film-forming, first polymer permeable to water and diltiazem, and a major proportion of a pharmaceutically acceptable film-forming, second polymer that is less permeable to water and diltiazem than the first polymer. The core and the coating layer both exclude organic acids. The composition of the coating layer as well as the proportion of core to coating layer are effective to permit release of the diltiazem allowing controlled absorption following oral administration.

Abstract: A modified release preparation having one or more coated core elements, each core element including an active ingredient and having a modified release coating, wherein a stabilising coat is provided between each core element and its modified release coating so that, upon in vitro dissolution testing, the amount of active ingredient released at any time on a post-storage dissolution profile is within 40 percentage points of the amount of active ingredient released at any time on a pre-storage dissolution profile.
