Describe the sequence of events that a drug undergoes from administration to
excretion Answer: 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.
