Attainment of steady state is not a linear process. It typically occurs after 4–5 half-lives, when 93.8–96.9% of the final steady state has been reached.

"WebJan 19, 2013 · Steady state is the point at which the average drug concentration plateaus. Time to steady state is determined by the drug’s half-life: steady state = 4.5 x half-life. In general, a drug’s half-life is increased in geriatric patients compared with younger patients, so that it takes longer to reach steady state. Changes in drug dosage are ...

WebThe plasma drug concentration–time curve of a drug given by constant IV infusion is shown in Fig. 5-1.Because no drug was present in the body at zero time, drug level rises from zero drug concentration and gradually becomes constant when a plateau or steady-state drug concentration is reached. At steady state, the rate of drug leaving the body is equal to the … WebPharmacokinetic data, particularly half-life, may be used to predict the time to steady state. For a drug with multi-exponential disposition, the effective half-life (t 1/2,eff) value, determined from the time to reach steady state, can better predict the accumulation and elimination of the drug than the terminal half-life (t 1/2,z) associated ...
