"Seven years ago, I graduated from Ulster University, where I received my pharmacy training. During my schooling, I found learning pharmacodynamics and pharmacokinetics to be the most challenging at first. After hiring a tutor, she taught me an easy way to remember the differences between the two. She described how pharmacokinetics is what the body does to the drug, while pharmacodynamics is what the drug does to the body. She drew a diagram, explained the differences, gave examples, and then it clicked. After that, it was much easier to learn what I was being taught, and her lesson has stuck with me to this day."
