The transdermal drug delivery system is technique that provides drug through the intact skin. Skin penetration enhancement techniques have been developed to increase the bioavailability of drug substance. These review describes various transdermal patches available in market, types of patches, basic components, polymer used in formulation. The novel drug delivery method do well and complete with those already on the market the main problem that requires consideration include device design and safety, efficacy, ease of handling and economical. Transdermal drug delivery system represent the most attractive method among these because of its low rejection rate, magnificent, ease of administration and better convenience and compliance with patient. This review article provide an overview of transdermal drug delivery system contains various innovative dosage forms. In comparison transdermal patch are effective due to its easy to apply and non-invasive.

The term mucoadhesion can be defined as a phenomenon of interfacial molecular attractive forces in the layer of surface of a biological membrane and the natural or synthetic polymer, which allows the polymer to the adhere the surface of that membrane for an extended as well prolonged period of time. Since the last four decades, the conception of mucoadhesion has achieved a important precious interest in the various fields of pharmaceutics

Transdermal drug delivery system has become a proven technology that offer significant clinical benefit over the dosage forms. Drugs with very short half-life, narrow therapeutic window, and poor bioavailability-transdermal drug system are convenient. Skin serves as site of drug application for local as well as systemic effects. There are wide varieties of drugs for which topical or transdermal is viable options

Recently, transdermal drug delivery system (TDDS) has become a more and more important approach to administering drugs. Based on its advantages, which are not achievable by other modes of administration, many researchers are dedicated to the study of it, and have made great progress. Although the skin offers a painless interface for systemic drug delivery, it also presents limitations which are mainly caused by the stratum corneum.

The aim of this study is to apply wet granulation on liquisolid powders to overcome issues of poor powder flowability and compressibility especially with using high viscosity liquid vehicles. Different liquisolid formulations were made using three excipients where the effect of each excipient used in the dissolution of the model hydrophobic drug (Glibenclamide) was evaluated. The Glibenclamide tablets were formulated using PEG 400, Synperonic PE/L44 and Cremophor ELP, at a 10 %w/w in liquid vehicle drug concentration. The carrier (Avicel®PH102) was used followed by colloidal silicon dioxide (coating material) that converted the wet mixture into dry powder. Potato starch, 5%w/w, as a disintegrant was mixed with the mixture manually for 10 minutes and was finalized by adding 0.75% of magnesium stearate as a lubricant.

Capsaicin, an active ingredient of Capsicum fruit, is currently undergoing “revival” in the clinical management of pain. However, the choice of its formulation is rather limited to the use of “old-fashioned” tinctures and recently the patches. In an attempt to improve the therapeutic outcome and develop its skin-friendly formulation, we prepared the vesicle-based drug delivery system with capsaicin.

In recent years many progress has been achieved in the biomedical and biopharmaceutical fields particularly in drug delivery and regenerative medicine. This has been possible thanks to the increased expertise in polymers chemistry as well as the advent of innovative techniques of materials manipulation that have lead to the production of new “smart” polymeric devices with peculiar propertiesable to selectively reach almost all areas of the human body, in the case of drug delivery systems, or to reduce the chemical-physical gap between human tissues and synthetic devices, in the case of tissue engineering.
