Abstract

A hydrogel is a water-insoluble three- dimensional polymers network that has the ability to absorb body fluids in a biological environment. Hydrogels are soft cross-linked polymeric materials that can store drug, and biomolecules for hydration and therapeutic applications. Hydrogels have been settled in pharmaceutical applications and become very popular due to their high-water content, soft consistency, flexibility and bioavailability. Hydrogel formulation were white, viscous creamy preparation with glossy texture. Natural and synthetic hydrophilic polymers can be cross-linked and modified in physical or chemical manner to obtain hydrogel. A properly cross-linked hydrogel can be converted by body to less toxic or non-toxic intermediate. The well -shaped hydrogels exhibited remarkable wet-tissue adhesion, suitable swelling and mechanical properties, sustained probiotic release and excellent storage durability.[1]
