AN OVERVIEW ON VARIOUS APPROACHES TO ORAL CONTROLLED DRUG DELIVERY SYSTEM VIA GASTRORETENTIVE DRUG DELIVERY SYSTEM
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2012, Vol 3, Issue 4
Abstract
In recent years scientific and technological advancements have been made in the research and development of oral drug delivery system. Oral sustained drug delivery system is complicated by limited gastric residence times (GRTs). In order to understand various physiological difficulties to achieve gastric retention, we have summarized important factors controlling gastric retention. To overcome these limitations, various approaches have been proposed to increase gastric residence of drug delivery systems in the upper part of the gastrointestinal tract includes floating drug dosage systems (FDDS), swelling or expanding systems , mucoadhesive systems , magnetic systems, modified-shape systems, high density system and other delayed gastric emptying devices.
