Difference between steady state and clearance

WebJun 30, 2015 · Half-life (t½) is the time required to change the amount of a drug in the body by one-half during elimination. The two main factors which affect drug half-life are volume of distribution and clearance; the formula for half-life is (t½ = 0.693 × Vd /CL). The 0.693 factor is in fact the logarithm of 2, which represents the fact that drug clearance typically … WebClearance defined Drug clearance is concerned with the rate at which the active drug is removed from the body; and for most drugs at steady state, clearance remains constant so that drug input equals drug output. Clearance is defined as the rate of drug elimination divided by the plasma concentration of the drug.

Is there a difference between equilibrium and steady state?

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 ... Steady state pharmacokinetics are important for chronically administered drug products.
