Renal Drug Excretion

Renal drug excretion consists of three different processes. These processes are (1) Glomerular filtration, (2) Passive reabsorption, and (3) Active transport or tubular secretion.

Glomerulus consists of a group of capillaries that are intertwined. In the process of glomerular filtration, drugs move from blood into urine. The drugs include all types of drugs with low molecular weight.

In the process of passive reabsorption, lipid soluble drugs move back into the blood.

In the process of active transport or tubular secretion, drugs move from blood to urine utilizing tubular “pumps” for organic bases and acids.
