a. Norplant?R is a reservoir delivery system. Draw a diagram showing its
important components. (You do not have to get a correct answer here, just
draw a cylindrical system that you think-based on what you learned in
the lecture-would work to produce 5 years of release.)
b. Recall the well-stirred model that we developed in class. Describe in
words how you would change this model to describe the changes in blood
concentration that occur after implantation of a Norplant?R system.
