Css in pharmacokinetics
WebOct 11, 2024 · Background Pharmacokinetics (PK) is the process of absorption, distribution, metabolism and elimination (ADME) of drugs. Some drugs undergo zero-order kinetics (ethyl alcohol), first order kinetics (piroxicam) and mixed order kinetics (ascorbic acid). Drugs that undergo Michaelis-Menten metabolism are characterized by either …

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 ...
