Absorption

- the movement of a drug from its site of administration into the blood. The rate of

absorption determines how soon effects will begin. The amount of absorption helps

determine how intense effects will be.

Distribution

- drug movement from the blood to the interstitial space of tissues and from there into

cells.

Determined by three major factors: blood flow to tissues, the ability of a drug to exit the

vascular system, and, to a lesser extent, the ability of a drug to enter cells

Metabolism

- the chemical alteration of drug structure.

(Most drug metabolism takes place in the liver)
