Drugs are metabolized mainly by the liver via phase I or phase II reactions. The purpose of both of these types of reactions is to:
1. Inactivate prodrugs before they can be activated by target tissues
2. Change the drugs so they can cross plasma membranes
3. Change drug molecules to a form that an excretory organ can excrete
4. Make these drugs more ionized and polar to facilitate excretion
