WebApr 13, 2024 · The maximum plasma concentration (Cmax) was reached in 6 days in both the 30 and 80 mg groups, with an elimination half-life of 18 days. The Cmax and area under the plasma concentration–time curve increased in a dose-dependent manner, and the trough concentration reached steady state by week 16. WebA drug is being given at a dosage of 3 mg/Kg q12h via IM injection. It is very rapidly absorbed. Its elimination half-life is 4 hours. Estimated Vd = 0.3 L/Kg. What is the concentration of the initial peak? What is the concentration of the peaks at steady state? What is the concentration of the troughs at steady state?
