How many doses to reach steady state

For example, perhaps you want to achieve a steady state of concentration (C ss) of 10 ng/mL, which requires a 30 mg dose once daily. However, it will take 10 days to achieve steady state. Assuming dose proportionality, a 60 mg dose would achieve a C ss of 20 ng/mL in 10 days also. See more There are several special PK parameters associated with steady state kinetics. These parameters are not necessarily more important; however, they are useful … See more The time to reach steady state is defined by the elimination half-life of the drug.
