Shorter half-life
Splet15. mar. 2024 · Shorter half-life drugs tend to take action quickly, and their effects may wear off rapidly as well. A long half-life drug, on the other hand, may stay in the body for longer than a person wants it to as the effects can be prolonged. What is half-life of a radioactive isotope?
