3- Complete absorption of drug from the floating formulation is expected even at alkaline pH of intestine. The dissolution occurs in gastric fluid and after emptying of the stomach contents the dissolved drug is available for absorption in small intestine.

5- FDDS improves patient’s compliance by reducing dosing frequency.
6- Better therapeutic effect achieved from short half-life drugs.
7- Because
