Define steady state for medication
“Steady state” is an important term in pharmacokinetics, but it can often seem a bit abstract and confusing to many. Here is how I define steady state: When the rate of drug input is equal to the rate of drug elimination, steady state has been achieved. See more There are several special PK parameters associated with steady state kinetics. These parameters are not necessarily more important; however, they are useful because of the unique situation when drug input rate and … See more The time to reach steady state is defined by the elimination half-life of the drug. After 1 half-life, you will have reached 50% of steady state. After … See more Steady state pharmacokinetics are important for chronically administered drug products. Understanding the basic concept that a drug reaches steady state once the rate of drug input and elimination are equivalent helps … See more WebUniversity of Nottingham
