TRANSDERMAL ADMINISTRATION Meaning and
Definition
-
Transdermal administration refers to the method of delivering drugs or medications into the bloodstream through the skin. This route of administration involves the application of patches or systems that are specifically designed to release the active substances slowly and steadily through the outer layer of the skin, known as the dermis, and into the blood vessels present beneath.
The transdermal route offers an alternative to traditional methods of drug delivery, such as oral ingestion or injection. With transdermal administration, the drug is absorbed directly into the bloodstream, bypassing the digestive system and the liver's first-pass metabolism. This allows for a more consistent and controlled release of the medication, potentially reducing side effects and increasing patient compliance.
Transdermal patches are commonly used to administer a wide range of medications, including hormones, nicotine, pain relievers, and anti-nausea drugs. The patches are typically thin, flexible, and adhesive, allowing them to be easily applied to the skin surface. The medication is then absorbed through the skin's layers and into the bloodstream over a period of time, depending on the specific patch design.
Overall, transdermal administration provides a convenient and non-invasive method of drug delivery. It offers advantages such as prolonged drug release, improved patient convenience, and the potential for bypassing the first-pass metabolism. However, the effectiveness of transdermal delivery can vary depending on factors such as skin permeability, the specific drug properties, and the formulation of the transdermal system.
