Gastro-retentive drug delivery system -The new approaches

Their primary objective is to prolong the residence time of a medication in the stomach, ensuring site-specific release in the upper gastrointestinal tract for both local and systemic effects.

Types of approaches of GRDDS

  • Floating systems-These systems, which include floating tablets and beads, use low-density polymers to remain buoyant in the stomach for extended periods.
  • Mucoadhesive systems-These systems adhere to the stomach mucosa to provide long-lasting local medication administration.
  • Swelling and expanding systems-These systems expand upon contact with gastric fluids to prevent premature emptying.
  • High-density systems-These systems sink to the bottom of the stomach and remain there longer.
  • Magnetic systems-These systems use external magnets to maintain the drug formulation within the stomach.

Gastric-retentive drug delivery systems are smart solutions that extend drug action by keeping medications in the stomach longer, using strategies like floating, mucoadhesion, swelling, high-density, or magnetic approaches

GRDDS enhances bioavailability, improves therapeutic efficacy, and is especially useful for drugs with narrow absorption windows or those unstable in intestinal environments.

That’s a great overview, gastro-retentive systems could really improve drug efficacy and patient compliance. :pill:

Which of these approaches do you think shows the most promise for widespread clinical use, and why?
