Transdermal drug delivery

Transdermal drug delivery methods, composite computer artwork. Transdermal devices deliver controlled doses of drugs through the skin directly into the bloodstream. At top is a transdermal patch. The drug is stored in the raised reservoir. This type of patch is commonly used for hormone replacement therapy (HRT) and nicotine patches. At centre is an electric patch. An electric current is passed through 2 electrodes on the skins surface, causing the drug to be pushed through the skin. This process, iontophoresis, is being developed for large ionised drug molecules. At bottom is an ultrasound machine, which uses ultrasonic frequencies to transfer high molecular weight drugs through the skin, a process known as phonophoresis

EDITORS COMMENTS
This print showcases the innovative world of transdermal drug delivery methods. Through this composite computer artwork, we are introduced to three different techniques that revolutionize how drugs can be administered directly into the bloodstream through the skin. At the top, we see a transdermal patch, commonly used for hormone replacement therapy (HRT) and nicotine patches. This patch stores the drug in a raised reservoir, allowing controlled doses to be delivered over time. In the center, an electric patch catches our attention. By passing an electric current through two electrodes on the skin's surface, iontophoresis is employed to push large ionized drug molecules through the skin. This method shows promise for delivering complex medications effectively. Finally, at the bottom of this image lies an ultrasound machine. Utilizing ultrasonic frequencies, this device enables high molecular weight drugs to permeate through the skin via phonophoresis—a process known as "sonic waves" treatment. Through these cutting-edge technologies depicted in this illustration featuring a male patient's arm being treated by a healthcare professional in their thirties or twenties; we witness advancements in medicine and technology merging seamlessly. The potential applications range from hormone replacement therapies and contraception methods to self-administered nicotine patches—all contributing towards improved health outcomes and enhanced patient care. This thought-provoking artwork from Science Photo Library encapsulates both scientific progress and medical ingenuity within its intricate details—highlighting how transdermal drug delivery continues to shape modern pharmacology practices without mentioning any commercial use or specific company involvement.
