Penetration Enhancement

Transdermal Drug Delivery System (TDDS) is described as a self-contained or discrete dosage form that is applied to the intact skin. This rout of drug administration of drugs through the skin for therapeutic use is an alternative approach to oral, intravascular, subcutaneous, and transmucosal routes. The delivery of drugs through the skin to the systemic circulation provides a convenient route of administration for a variety of clinical indications. Transdermal Drug Delivery System allows continuous drug administration, use of drugs with short biological half lives, avoids increases hepatic first pass elimination and rapid termination of medication by removing the transdermal drug delivery system from the skin.  Various transdermal technologies may be applied for different categories of pharmaceuticals used for the treatment of disorders of the skin or for systemic effects to treat diseases of other organs. Several transdermal products and applications include hormone replacement therapy, contraception, pain management, angina pectoris, smoking cessation, and neurological disorders such as Parkinson's disease. The most commonly used transdermal system is the skin patch using various types of technologies. Stratum corneum is the outermost layer of the skin and it is the main barrier layer for permeation of drug in transdermal delivery of drugs. So, to circumvent the barrier properties of stratum corneum and to increase the flux of drug through skin membrane various penetration enhancement techniques are used in transdermal drug delivery system. The review presents different physical and chemical methods in penetration enhancement approaches and to optimize the transdermal delivery system.

Novel Drug

Transdermal drug delivery systems (TDDS), also known as patches, are dosage forms designed to deliver a therapeutically effective amount of drug across a patients skin. In order to deliver therapeutic agents through the human skin for systemic effects, the comprehensive morphological, biophysical and physicochemical properties of the skin are to be considered. Transdermal delivery provides a leading edge over injectables and oral routes by increasing patient compliance and avoiding first pass metabolism respectively. Transdermal delivery not only provides controlled, constant administration of the drug, but also allows continuous input of drugs with short biological half-lives and eliminates pulsed entry into systemic circulation, which often causes undesirable side effects. The TDDS review articles provide valuable information regarding the transdermal drug delivery systems and its evaluation process details as a ready reference for the research scientist who is involved in TDDS. With the advancement in technology Pharma industries have trendified all its resources. Earlier we use convectional dosage form but now we use novel drug delivery system. One of greatest innovation of novel drug delivery is transdermal patch. The advantage of transdermal drug delivery system is that it is painless technique of administration of drugs.

Transdermal drug delivery system used to transport the drug across the skin deep into systemic circulation. The main advantages of Transdermal drug delivery system improved patient compliance, sustained release, avoidance of gastric irritation, as well as elimination of pre-systemic first-pass effect. But most of therapeutic agents is limited due to thickness of stratum corneum, which act as a barrier for the delivery of various drug molecules and only few molecules are able to reach the action site. Microneedles are the new form of delivery system, which are used to increase the delivery of drug through this route and overcoming the number of problems related to conventional drug delivery system the main aim of this review to focus on new innovation in transdermal drug delivery systems. In the microneedle drug delivery system, the skin is temporarily broken, that creating micron size pathways that deliver the sufficient amount of drug directly into the stratum corneum from which the drug can directly go into the systemic circulation. In this review, we describe different type of microneedles can be solid, coated, dissolving and biodegradable microneedles and their method of fabrication. Microneedles can be manufactured in different forms like hollow, solid, and dissolving. Also describe materials used for fabrication, fabrication techniques, methodology of drug delivery such as Poke and patch, Coat and poke, Poke and release, Poke and flow and evaluation parameters.

Nanoemulsions are drug transporters for the delivery of therapeutic agents. They possess the small droplet size having the range of 20×10-9-200×10-9m. The main purpose of using Nanoemulsion is to enhance the drug bio- availability of transdermal drug delivery system. With the help of phase diagram, we can select the components of nanoemulsion depending upon formulas ratio of oil phase, surfactant/co-surfactant and water phase. Nanoemulsion directly used as a topical drug delivery in skin organs. The most useable pharmaceutical application has been developed till date to provide systemic effects to penetrating the full thickness of skin organ layer nanoemulsions can be administered through variety of routes such as percutaneous, perioral, topical, transdermal, ocular and parental administration of medicaments. Nanoemulsions are transparent and slightly opalescent. Nanoemulsion can be prepared through various methods. Nanoemulsions are transparent and slightly opalescent. Factor affecting nanoemulsions are surfactant, viscosity, lipophilic, drug content, pH, concentration of each component, and methodology of formulation. It is unfeasible to test all factors at the various levels. Design of formulation when it comes to experimental design it gives an excellent approach through reducing the time and money.

Pass Metabolism

In the recent days about 75% of the drugs taken orally are does not show the desired therapeutic effect. Oral conventional dosage forms have several disadvantages such as poor bioavailability due to hepatic first pass metabolism and tendency to produce rapid blood level spikes (Both high and low). Thus, rapid drug levels in the plasma leads to a need of high and/or frequent dosing, which can be both uneconomical and inconvenient. To overcome such disadvantages transdermal drug delivery system was developed. TDDS is such a delivery system which has been explored extensively over the last two decades, with therapeutic success. Transdermal drug delivery systems (TDDS) are the drug delivery systems which involves transportation of drug to epidermal and dermal tissues of the skin for local therapeutic action while major fraction of the drug is transported into the systemic blood circulation. Topical administration of therapeutic agents offers vast advantages over conventional oral and invasive methods of drug delivery. Some of the advantages of transdermal drug delivery include limitation of hepatic first pass metabolism, enhancement of therapeutic efficiency and maintenance of steady state plasma level concentration of the drug. This study includes a brief overview of TDDS, its advantages over conventional dosage forms, drug delivery routes across human skin, permeation enhancers, and classification, formulation, methods of preparation and evaluation of transdermal patches.
