Transdermal Gels: A Soft Revolution in Drug Delivery Technologies

The benefits of topical drug administration include extended half-lives and direct delivery of the medication to the site of action. The skin serves as the primary channel for topical drug delivery systems and is one of the most accessible and widely distributed organs on the human body. Numerous commonly used topical medications, such as. The fact that ointments, creams, and lotions are typically quite sticky and make patients uncomfortable when applied is just one of their many drawbacks. The paper also includes a brief discussion of hydrogels, which are three-dimensional structures that can hold large amounts of water and allow biological fluids to swell. In-situ gels are an innovative method in pharmaceutical gel technology. An example of in-situ gels is hydrogels, which are solution-like but form a gel when they come into contact with bodily fluids or when their pH changes. Several polymers, including carbopol-934, HPMC, guar gum, xanthan gum, carrageenan, xyloglucan, pectin, chitosan, and others, are utilised in in-situ gelling systems. The classification, formulation mechanism, and application of gels and hydrogels (in-situ gels) as innovative pharmaceutical approach systems are the primary topics of this paper.
