The study of the drug concentration and drug effects on the body

phase in which the drug becomes solution so that it can cross the biologic membrane

fillers and inert substances used in drug preparation

break down of a tablet into smaller particles

dissolving of the smaller particles in the GI fluid before absorption

time it takes a drug to disintegrate and dissolve to become available for absorption

process of drug movement to acheive drug action

mainly diffusion; doesn't require energy

requires a carrier like an enzyme or protein to move a substance against a concentration gradient

process by which cells carry a substance across their membrane by engulfing the substance

also called hepatic first pass; process by which a substance passes to the liver first; the liver metabolizes the substance
