Abstract

Gastro-retentive systems are often produced in order to modulate drugs release from pharmaceutical forms and in this way to increase drug residence time in the gastrointestinal tract. One of the most interesting strategies consists in the preparation of floating devices. These can be classified into two groups: effervescent systems and non-effervescent systems. A review of what has been done in the last years is presented in this article.
