In vitro sodium salicylate release from a sucrose polyester matrix

Area of Science:

• Polymer Science
• Drug Delivery Systems
• Materials Science

Background:

• Sucrogel H-70 is a novel polyester synthesized from sucrose.
• Drug delivery systems require matrices that ensure predictable drug release.
• Polyester matrices are explored for their potential in controlled drug release applications.

Purpose of the Study:

• To investigate Sucrogel H-70 as a potential drug delivery matrix.
• To evaluate the release kinetics of sodium salicylate from Sucrogel H-70.
• To assess drug release behavior in different simulated physiological media.

Main Methods:

• A reservoir-controlled release device was utilized.
• Sodium salicylate was employed as the model drug.
• Release studies were conducted in water, simulated gastric fluid, and simulated intestinal fluid.

Main Results:

• Sodium salicylate release from Sucrogel H-70 was observed.
• The drug release profile followed zero-order kinetics.
• Consistent release kinetics were observed across all three tested media.

Conclusions:

• Sucrogel H-70 demonstrates suitability as a drug delivery matrix.
• The zero-order release kinetics suggest predictable and sustained drug delivery.
• Sucrogel H-70's performance in simulated gastric and intestinal fluids indicates potential for oral drug delivery applications.
