Gastroretentive Drug Delivery System Ppt PDF
gastroretentive drug delivery system, several techniques are currently used such as hydrodynamically balanced systems (HBS) / floating drug delivery system, low-density systems[4-6], raft systems incorporating alginate
FLOATING DRUG DELIVERY SYSTEM: Floating systems or Hydrodynamically controlled systems are low-density systems that have sufficient buoyancy to float over the gastric contents and remain buoyant in the stomach without affecting the gastric emptying rate for a
drug delivery system. IV Gastroretentive drug delivery systems. The following are different gastroretentive drug delivery systems: A) Floating systems [S. Stithit et.al, S. Arora et.al., P. Mathur et.al., H.Dutt et.al.]:
