The circulating blood distributes the drug to the capillary level, where the drug
leaves the circulation and enters the interstitial fluid. The interstitial fluid
bathes the cell or bind with surface receptors. The drug then exits the cell or its
surface, moves back to interstitial fluid, reenters circulation and then is
metabolized in the liver and sent to the kidneys for excretion.
