Area of Science:

  • Pharmacology
  • Drug Delivery Systems
  • Gastrointestinal Physiology

Background:

  • Gastroretentive drug delivery systems aim to increase gastric retention time.
  • Various approaches like floating, swelling, mucoadhesive, and high-density systems have been investigated.
  • Gastric pH and motility variability significantly influence drug release and retention.

Purpose of the Study:

  • To review gastric physiology.
  • To present various intragastric drug delivery systems.
  • To highlight the potential of gastroretentive systems.

Main Methods:

  • Literature review of gastroretentive delivery systems.
  • Discussion of gastric physiology and its impact on drug delivery.
  • Analysis of different gastroretentive system designs.

Main Results:

  • Floating drug delivery systems have demonstrated promising results for gastric retention.
  • Variability in gastric physiology presents challenges for consistent drug delivery.
  • Multiple strategies exist to enhance drug residence time in the stomach.

Conclusions:

  • Gastroretentive systems offer a viable approach to prolonging drug action in the stomach.
  • Understanding gastric physiology is crucial for designing effective delivery systems.
  • Floating devices represent a key strategy in gastroretentive drug delivery development.
