What is the formula to predict drug concentrations over time?

C2 = C1 x e^-kt
Ke = ln(C1/C2)/t
0.693/ke
(Desired concentration x Vd) / F

The correct answer is: C2 = C1 x e^-kt

The correct formula to predict drug concentrations over time is C2 = C1 x e^-kt. This formula utilizes the initial drug concentration (C1), the elimination rate constant (k), time (t), and the resulting drug concentration at a specific time (C2). By using this formula, pharmacists can estimate the drug concentration at different time points and adjust dosing regimens accordingly.
