ABSTRACT

Thermo sensitive hydro gel formulation contains polymeric materials. Hydrogels are hydrophilic, highly water swell able polymer networks which capable to converting chemical energy into mechanical energy and vice versa. They can be tailored regarding their chemical nature and physical structure, sensitiveness to external stimuli and biocompatibility. Hydrogel are water swollen polymeric material and that able to maintain a distinct three dimensional structure. Hydrogels are sensitive to different environmental stimuli like pH, temperature, ion, electric signals, light, pressure, antigen specific, enzyme sensitive, and glucose levels. Hydrogel used in delivery of drug through various routs like ophthalmic parentral drug, oral, nasal TDDS and also in NDDS like in nanoparticles. Now a day’s stimuli sensitive hydrogels are also used in administration of DNA.
