Fraction of Drug Unbound in Plasma given Plasma Volume Solution

Follow our step by step solution on how to calculate Fraction of Drug Unbound in Plasma given Plasma Volume?

FIRST Step Consider the formula

fu = (\frac{V d - V P}{V T}) \cdot fu t

Next Step Substitute values of Variables

∴

fu = (\frac{9L - 5L}{3.5L}) \cdot 0.7

Next Step Convert Units

∴

fu = (\frac{0.009m³ - 0.005m³}{0.0035m³}) \cdot 0.7

Next Step Prepare to Evaluate

∴

fu = (\frac{0.009 - 0.005}{0.0035}) \cdot 0.7

LAST Step Evaluate

∴

fu = 0.8
