1. A lipid-soluble medication will be eliminated more quickly and not work as well.
2. A lipid-soluble medication will accumulate in fat tissue and its duration of action may be prolonged.
3. Absorption of lipid-soluble drugs is impaired in older adults.
4. The bioavailability of the lipid-soluble drug will be increased in older adults.
