Development of long-acting nitrate delivery systems

In this paper pharmaceutical and biopharmaceutical aspects on the development of long-acting nitrate delivery systems are reviewed. Basic considerations and requirements are also discussed. Recent product development activities are presented, with an emphasis on nitroglycerin in transdermal form and oral isosorbide-5-mononitrate controlled-release formulations.
