Knowledge of the relationships among dose, drug concentration drug
concentration in blood, and clinical response (effectiveness and
undesirable effects) is important for the safe and effective use of drugs in
individual patients. This information can help identify an appropriate
starting dose, the best way to adjust dosage to the needs of a particular
patient, and a dose beyond which increases would be unlikely to provide
added benefit or would produce unacceptable side effects.
