Introduction Elimination is a pharmacokinetic process that describes the irreversible removal of active pharmaceutical ingredients from the body. It is composed of biotransformation (metabolism) and excretion (elimination). The most important organs for excretion are the kidney and the liver. However, drugs can also be excreted through the respiratory tract, hair, saliva, milk, tears, and sweat. … Elimination

They can be filtered at the glomerulus of the nephron, actively secreted at the proximal tubule, and reabsorbed at various tubular segments. In renal insufficiency, these processes are impaired. This may result in a renally … Dose Adjustment in Renal Insufficiency
