Summary for Patent: 5,202,128
Title: Sustained release pharmaceutical composition
Abstract:The present invention relates to a pharmaceutical pellet composition having a core element including at least one highly soluble active ingredient and a core coating which is partially soluble at a highly acidic pH. The pharmaceutical composition provides a slow release of active ingredient at a highly acidic pH and provides a constant, relatively faster rate of release at a more alkaline pH such as that of the intestine.
