steady-state concentration

Steady-state concentration refers to the point during continuous drug administration where the amount of medication entering the bloodstream equals the amount being eliminated. At this stage, the drug level in the body remains consistent over time, without increasing or decreasing. This balance occurs after initial buildup and is important because it indicates the optimal, stable dose needed to maintain the desired therapeutic effect while minimizing side effects. Achieving a steady state typically takes several doses, depending on how quickly the body processes the drug.
