All of the following are reasons for reducing drug dosage in elderly, EXCEPT:
Correct Answer: Have increased baroceptor sensitivity
Description: Baroreceptor sensitivity decreases with aging. This decline in baroreceptor sensitivity alters the central nervous system control of sympathetic nervous outflow. Due to this insensitive baroreceptor, large change in blood pressure is needed to activate the baroreceptor and produce an appropriate compensatory response. So for bringing out a desired effect, the drug dosage should be increased in elderly.
