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.
