Swellable hydrogel-Based Drug Delivery System


The porous structure and swelling properties of hydrogels make them ideal for use as drug delivery vehicles. CD Bioparticles is an experienced drug delivery company which provides customized solutions for developing and producing new, biocompatible drug delivery systems. CD Bioparticles can provide you with development, design and testing services for environmentally responsive hydrogels and traditional hydrogels, facilitating the development of new drug delivery systems for our customers.

Introduction to Swellable Hydrogel

Hydrogels are defined as three-dimensional (3D) networks of hydrophilic molecules or polymers that are capable of swelling in water and retaining large amounts of water in their bulk. Hydrogels have become excellent controlled-release drug delivery vehicles in therapeutic areas such as targeted anticancer, bacterial infections, diabetes, gastric ulcers, etc., due to their porous nature, adjustable network structure, biocompatibility, and controlled swelling properties. By controlling the degree of cross-linking of the gel matrix and modifying environmentally responsive molecules, it is possible to achieve on-demand release at specific sites. In addition, the porous nature of hydrogels allows for the loading of more drug molecules while protecting them from complex environmental damage. Drugs elute slowly through hydrogel formulations, maintaining high drug concentrations in the target and surrounding tissues to enhance therapeutic efficacy.
