Properties of GI Tract Influence Drug Delivery

We rely on drugs to make us healthy when we are sick and to keep us healthy when we are well.  We can:

swallow them or

inject.gif (3481 bytes)
inject them or

inhale.gif (2101 bytes)
inhale them.

but the trick is to make these drugs chemically available to our body's systems as they are needed.

The resident acidity and basicity of the GI tract, particularly the stomach and small intestines and the properties of our blood supply, determine the concentration of drugs available for absorption.  In this section the concepts of equilibrium and acid/base character show how drug concentration is influenced.
