Innovative methods of gastroretentive sustained-release drug delivery

The current study''s objective is to create and evaluate an effervescent-based sustained-release floating drug delivery system (FDDS) for carvedilol that has a 12-hour dissolving time to reduce the frequency of its administration. Over the past 20 years there has been a huge desire for more dosage forms that are acceptable to patients. Because of this their technologies are more in demand than ever. Since creating a new chemical entity is very expensive pharmaceutical companies are focusing on creating novel drug delivery systems for their existing medications that have improved efficacy and bioavailability along with a lower dose frequency to lessen side effects.
