Clinical significance of determination plasma half life of drug?

Plasma half life is the most important factor determining the dosage frequency. it also decides the time taken for the drug to reach steady state plasma concentration, which takes about 4-5 half lives to achieve. we can calculate how long the drug is going to stay in the body by knowing its half life as it is the time taken for the drug concentration to halve.
