Difference between steady state and clearance

WebThe term clearance describes the process of drug elimination from the body or from a single organ without identifying the individual processes involved. Clearance may be defined … WebA steady state solution is a solution for a differential equation where the value of the solution function either approaches zero or is bounded as t approaches infinity. It sort of feels like a convergent series, that either converges to a value (like f(x) approaching zero as t approaches infinity) or having a radius of convergence (like f(x ...
