Final answer:
An advantage of having pills, capsules, or liquid formulations is the convenience and ease of administration.
Step-by-step explanation:
An advantage of having pills, capsules, or liquid formulations is the convenience and ease of administration. Pills and capsules are solid forms of medication that can be easily swallowed, while liquid formulations allow for more precise dosing and can be easier to swallow for those who have difficulty swallowing solid forms. For example, children or elderly individuals may have difficulty swallowing pills, but can easily take liquid medicines. Additionally, liquid formulations can be more quickly absorbed by the body compared to solid forms.
