Question 1.The elderly are at high risk of ADRs due to:
Having greater muscle mass than younger adults, leading to higher volume of
distribution
The extensive studies that have been conducted on drug safety in this age
group
The blood-brain barrier being less permeable, requiring higher doses to achieve
therapeutic effect
Age-related decrease in renal function
Question 2. The point in time on the drug concentration curve that indicates the first sign of a

Minimum adverse effect level
Peak of action
Onset of action
