The times needed for the medicine to start producing a therapeutic response and for that response to reach its maximum are called the "onset of action" and the "peak level," respectively.
The number of drugs entering the body and the amount being removed equally each other at some point. We refer to this as a "steady state." A drug's steady state is reached after 5 to 6 half-lives, on average.
