A Review on Hydrogels and Organogels

Organogels and hydrogels are efficient semi-solid drug delivery devices with several uses in biological and pharmaceutical fields. The hydrophilic polymeric networks that make up hydrogels are able to absorb huge volumes of water without dissolving, which makes them extremely biocompatible and resembles genuine tissue in texture. Their sensitivity to environmental factors like light, temperature, and pH enables precise and regulated medication release. Hydrogels' high-water retention and flexibility make them ideal for application in gene therapy, wound healing, tissue engineering, and oral or rectal medication delivery. Organogels, on the other hand, are made with organic gelators and solvents such as fatty acids, lecithin, or sorbitan derivatives. In addition to being moisture-resistant and thermodynamically stable, these gels are perfect for administering hydrophilic and lipophilic medications via parenteral, transdermal, and cutaneous routes. In addition to being simple to make, organogels have outstanding penetrating qualities. Numerous approaches can be used to modify their rheological and structural characteristics, which makes them appropriate for use in topical treatments, implants, and cosmetics. Hydrogels and organogels together offer a viable platform for upcoming drug delivery innovations.
