With advancements in technology, TDS has become more sophisticated, incorporating features such as programmable release rates and multi-layered designs to enhance drug efficacy and safety.
How Does TDS Work in Medicine?
The mechanism of TDS in medicine is rooted in the principles of transdermal absorption, where drugs pass through the skin's layers to enter the bloodstream. The skin, being the body's largest organ, serves as both a barrier and a gateway for drug delivery. The outermost layer, the stratum corneum, acts as the primary obstacle, limiting the passage of substances. To overcome this, TDS patches are designed with permeation enhancers and specialized formulations that facilitate drug penetration.
Once the patch is applied, the drug is released from the reservoir or matrix layer and diffuses through the skin's layers. The drug molecules then enter the capillaries beneath the skin, where they are transported to the systemic circulation. This process ensures a steady and controlled release of medication, avoiding the peaks and troughs associated with oral or injectable drugs. The controlled release mechanism of TDS in medicine is particularly beneficial for maintaining therapeutic drug levels over extended periods.
Modern TDS in medicine also incorporates advanced technologies to enhance drug delivery. For instance, iontophoresis and sonophoresis are techniques that use electrical currents or ultrasound waves to improve drug permeation through the skin.
