Overview & Routes
The big picture — the drug's whole ADME journey, and every door into the body.
How the Body Handles a Drug: The ADME Story
You swallow one small tablet for a fever. Over the next eight hours that tablet is absorbed, carried, chemically rebuilt, and finally thrown out — a four-act journey the body performs on every drug you ever take. Learn the four acts (ADME) and one simple curve, and you can predict how fast a drug works, how long it lasts, and why the same dose can be safe in one patient and toxic in another.
Every Door Into the Body: Routes of Administration
The same drug can save a life in ten seconds or ten minutes — depending only on which door you send it through. Swallowed, injected, inhaled, slipped under the tongue, or stuck to the skin: each route trades speed for safety, convenience for control. Learn the doors and you'll understand why a code-blue drug goes in a vein while a nicotine patch goes on an arm.
