What is the benefit of using a transdermal patch for medication delivery?

Using a transdermal patch for medication delivery primarily allows for avoidance of injections, making it a less invasive option for patients. This delivery method enables medications to be absorbed directly through the skin into the bloodstream, providing a steady release over time.

Transdermal patches can enhance patient compliance because they eliminate the discomfort and anxiety often associated with needles, making it easier for patients to manage their medications without the need for frequent visits for injections.

The other options do not accurately reflect the primary benefits of transdermal patches. While patches can provide some level of immediate effect depending on the medication, they are generally designed for sustained, long-term release rather than quick onset. They are typically designed for infrequent reapplication—often daily, weekly, or even longer—contrary to the assertion of requiring frequent reapplication. Additionally, transdermal patches do not have to be taken with food, which is a consideration more relevant to oral medications.
