WebJul 28, 2024 · In pharmacokinetics, the Css refers to the situation where the overall intake of a drug is fairly in dynamic equilibrium with its elimination. In practice, it is generally considered that Css is reached after 4–5 times the half-life for a drug (T 1/2). In some medical conditions, the time to attain Css after multiple doses of a drug is too ...
