Describe the sequence of events that a drug undergoes from administration to
excretion
Drug is absorbed (or placed directly) into the bloodstream, the drug may bind with
plasma in the blood or may exist in free state, circulating blood distributes drug to
capillary level where it leaves circulation and enters interstitial fluid. it bathes the
cell and allows drug to bind to cell surface receptors or enter the cell. It then exits
the cell and moves back into interstitial fluid, reenters circulation, and is
transported to liver for metabolism. The metabolite is then transported to kidneys
for excretion.
