elderly patient experiencing an adverse drug reaction? -
ANSWER obtaining a thorough drug history that includes
over-the-counter medications
considering pharmacokinetic and pharmacodynamics
changes due to age
monitoring the patient's clinical response and plasma drug
levels
using the simplest regimen possible
