"Regular doses are given based on the half life of the medication to maintain a therapeutic effect"
"We try to give the next dose of medication only after the last dose is gone"
"The time between medication varies to fit the nurse's schedule"
"We need to vary the times of administration to keep the blood levels fluctuating"
