none

The unchanged drug or its metabolites are filtered through the glomeruli of the kidney and are concentrated in the renal tubular fluid. Active secretion transports the drug from the bloodstream across the renal tubular epithelial cells and into the renal tubular fluid. With most drugs, passive tubular diffusion (or passive reabsorption) plays a part in regulating the amount of drug in the tubular fluid.

Drugs are bound reversibly to plasma proteins such as albumin and globulin, and only the concentration of the unbound drug in the plasma is available for drug action. Although blood flow to the organ, drug solubility, and tissue barriers have an effect, only the free drug is active.

none

The half-life of a drug is the amount of time it takes for the concentration of the drug to fall to one half of its blood level. A drug with a short half-life will be quickly removed from the body and will require more frequent dosing.
