A review on hydrogel pharmaceutical preparations

Hydrogels are very important formulations in the pharmacy. They were having the swelling property and varying degree of flexibility similar to the natural tissue. They are trapping large quantities of water in their net like structure and can shrink when they were dried.Hydrogels are having good transport properties when they are given in parenteral route. Hydrogel are expensive and non- adherent. They are employed in developing transdermal drug delivery systems, tissue engineering’s, and regenerative medicines. Hence hydrogels are having very important role in pharmacy. Many drugs are formulated by using this technique.
