This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Pharmacology
All of the following are reasons for reducing drug dosage in elderly, EXCEPT: 
Select and explain. 
A. They are lean and have low body mass, B. Have reduced renal function with age, C. Have increased baroceptor sensitivity, D. Have reduced hepatic metabolism
C: Have increased baroceptor sensitivity
Answer: C: Have increased baroceptor sensitivity 
Explanation: 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.
