Mean plasma concentration-time curve

WebA general form of such a function as a plasma drug concentration—time curve is given by: (1) C = ∑ i = 1 n A i ∙ e − λ i ∙ t A variable C is a plasma drug concentration at time t , and − λ i is a constant that defines a log-linear slope of each exponential function as − λ / Ln 10 or − λ /2.303 , and has a unit of reciprocal ... WebTime course of the plasma concentration of a drug administered by the extravascular route. The same data are displayed as linear (LIN/LIN) and semilogarithmic (LIN/LOG) plots. Dose: 5 mg, Cmax: 30 μg L −1, AUC: 420 h μg L −1, and t1/2 8 h. No lag time is observed here.
