What does it mean to increase half-life?
It means the more the drug is distributed in the body, the more the half-life is. The half-life is inversely proportional to clearance, which indicates that the more the drug clearance from the body, the less the half-life is.

Why is half-life important?
Understanding the concept of half-life is useful for determining excretion rates as well as steady-state concentrations for any specific drug.
