You could respond with a thoughtful note that acknowledges their explanation and perhaps adds some personal insights or questions. Here’s an example of what you might say:
"Great summary of the different medication routes! It’s interesting to see how each method has its unique absorption rate and application. I particularly find the transdermal method fascinating—it's amazing how a patch can deliver medication over time. Have you ever used a transdermal patch yourself, or do you have a preference for any specific route based on experience? Additionally, I wonder how these different absorption rates affect patient compliance and overall treatment effectiveness. I'm looking forward to hearing your thoughts!"
