Abstract
Background: Oral route of drug administration has been the most common route of drug administration since the beginning of the therapeuticarea in medical science. However this route of drug administration fails at bypassing the first pass metabolism of the drug in liver with poor bio availability. Oral route of drug administration also fails in uncooperative /unconscious semiconscious / pediatric subjects. Transdermal patch, a new drug delivery system through skin to the parenteral circulation has been the most recently discussed topic in pharmacology and medicine as it is a noninvasive route of drug administration, delivered in a sustained / pre fixed dosage with no / extremely less first pass metabolism and better bio availability. Most importantly it can be used in semiconscious / unconscious & pediatric subjects without affecting their hemodynamics. The transdermal patches have many beneficial factors however they also come with some major drawbacks like varieties of formulation, design and quality of adhesiveness. This articles provides an insight of transdermal patch in terms of its mechanism of action, advantages, disadvantages and future scope of it in the medical science.
