The purpose of using a transdermal system is primarily for what reason?

1. Quick onset of action

2. Minimizing first-pass metabolism

3. Increased patient compliance

4. Reduced side effects

The correct answer is: Increased patient compliance

The transdermal system is designed to deliver medication through the skin, providing a sustained release of the drug into the bloodstream over an extended period. This method of delivery significantly enhances patient compliance, as it simplifies the administration process. Patients do not need to remember to take oral medications multiple times a day; instead, they can apply a patch that delivers the medication consistently over time. The convenience of having a less frequent dosing schedule, along with the non-invasive nature of the transdermal system, helps ensure that patients adhere to their treatment regimens more effectively. This is particularly beneficial for patients who may struggle with traditional oral medications due to forgetfulness, difficulty swallowing pills, or other adverse reasons. While minimizing first-pass metabolism, achieving a quick onset of action, and reducing side effects are relevant considerations for certain medications and delivery methods, the primary advantage of transdermal systems lies in their ability to improve patient compliance over typical administration routes. This makes the answer particularly fitting in the context of medication delivery systems.
