Figure 5.1. The mass of nicotine released from PCL, M, as a function of time. Diamonds denote 10% initial loading, Squares 40% initial loading, and circles 50% initial loading. The dashed lines show the maximal amount of drug in the system. Arrows mark the time at which 100% release was achieved. Solid lines are the result of a fit using equations (1-3).
