Cmax vs steady state

WebJan 22, 2024 · As a result, drug concentrations in the body remain constant (steady). Another way to think about steady state: After Dose 1: There are 0.5 doses left at the end of the dosing interval. This means we're at 50% steady state. After Dose 2: There are 1.5 … WebDistributional and postdistributional peak concentrations, along with the last obtained concentration in serum, were utilized to compare the following pharmacokinetic variables: volume of distribution at steady state (Vss), half-life, clearance (CL), and maximum concentration in serum (Cmax).

WebThe median time to maximum plasma concentration of vardenafil is 0.6–0.9 h for all doses. Half-life is similar to sildenafil (i.e., approximately 4 to 5 h). C max of vardenafil may be reduced by 20% following consumption of a high-fat meal (57% fat), but is unaffected by a meal of 30% (or less) fat. WebJun 26, 2024 · a Tau is required for steady-state data only. Models 200–202 can be used for either single-dose or steady-state data. For steady-state data, the computation assumes equal dosing intervals (Tau) for each profile, and that the data are from a “final” dose given at steady-state. ...
