In present scenario more than 70% of the drugs that are taken by oral route are found to be less effective as desired, to overcome this constraint Transdermal drug delivery system has emerged as an innovative area of research, this system helps in delivering the drugs and macromolecules through skin into systemic circulation. At present, the worldwide market of Transdermal patch has reached 2 billion pounds. Many drugs like Estrogen, Progestrone, Nitroglycerine, Clonodine etc. are fabricated in form of Transdermal patches due to its ability to deliver the drug in non-invasive manner and also to overcome the problems associated with oral route. Although the Transdermal patches deliver the drug at predetermined rate1, the partitioning of drug from the system to the skin and then penetration through different layers of skin can be altered by adding penetration enhancers that can be physical or chemical in nature. This article deals with the role of different chemicals that can be used as penetration enhancer. Keywords: Penetration enhancer, Layer of skin, Fatty alcohol and glycol

Objective: Medroxyprogesterone Acetate (MPA) using a transdermal drug delivery system for contraception by passive diffusion is limited by the skin barrier properties. Penetration enhancers such as olive oil (fatty acid permeation enhancer) and DMSO (chemical enhancer) can be used. The objective of this study was to overcome MPA penetration problem by using olive oil and DMSO. Methods: An in vitro penetration study using the Franz diffusion cells was performed. The first penetration study used MPA in olive oil (O) and MPA in coconut oil (C) with the concentration 100 μg/ml to each sample and MPA suspension as a control with the same concentration. The second study used MPA in olive oil with the concentration 200.0 μg/ml (A), MPA in olive oil with 0.5% DMSO with the concentration 200.0 μg/ml (B), and MPA in olive oil with 1% DMSO with the concentration 200 μg/ml (C). Results: MPA penetration test for olive oil+0.5% DMSO had flux value 4.24±0.074 μg/cm2. hr and it was not significantly different (t-test, P>0.05) with olive oil+1% DMSO. While the MPA penetration test in only Olive oil had flux value 0.90±0.0087 μg/cm2. hr. Conclusion: This research concluded that olive oil and 0.5% DMSO could improve the penetration of MPA into skin membrane by 4.5 times more than olive oil alone.

Transdermal Patches

Transdermal drug delivery is an alternative route for systemic drug delivery which minimizes the absorption and increases the bioavailability. Orally clopidogrel bisulfate has a short elimination half-life (7-8 h), low oral bioavailability (50 %) undergoes extensive first pass metabolism (85 %) and frequent high doses (75 mg) are required to maintain the therapeutic level as a result. The purpose of this research was formulation and evaluation of transdermal drug delivery system of clopidogrel bisulfate using various polymers such as HPMC and EC by solvent casting technique for improvement of bioavailability of drug and reducing toxic effects. The developed transdermal patches may increase the therapeutic efficacy and reduce toxic effect of clopidogrel bisulfate. The prepared transdermal drug delivery system of clopidogrel bisulfate using different polymers such as HPMC and EC had shown good & promising results for all the evaluated parameters. Based on the in vitro drug release, drug content, weight variation, tensile strength, thickness and folding endurance results formulation F2 was concluded as an optimized formulation which shows its higher percentage of drug release.

Conventional Dosage

Recently, most widely using conventional dosage form such as tablet, capsules, and injections but due to some case we are preferable to choose transdermal drug delivery system (TDDS) because conventional oral dosage form undergo first pass metabolism. In TDDS, skin is the effective medium for the penetration of drug into systemic circulation. This system required very low dose for the effective result or action. One of the major disadvantages of TDDS is penetration rate is very low through the stratum corneum. Nowadays, different types of skin penetration enhancement techniques are used for increasing the penetration. These types of techniques can be also increase the bioavailability. The patients have more preferable to choose this type of drug delivery system because it has more advantages than conventional dosage form. This article is discuses about the anatomy and physiology of skin and its drug penetration capacity, polymers used in transdermal drug delivery and different types of TDDS.

Conventional Dosage

Conventional dosage forms which require multidose therapy have many problems and complications. Design of a conventional dosage forms should be such that it delivers right amount of drug in right manner to the target site. The encouragement in development of novel drug delivery system is apart from therapeutic efficacy is its cause. Redesigning the unit and means is a difficult task and profitable task so a controlled released drug delivery system, a novel drug delivery system evolves which facilitates the release of drug at predetermined rate. Controlled drug delivery can be achieved by transdermal drug delivery system which can deliver the drug through skin to the systemic circulation at a predetermine rate over a prolonged period of time.

Materials Used

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.
