Most drugs are either excreted in the urine (via the kidneys) - particularly if they are very water soluble - or sometimes metabolized - mostly in the liver.
Urine is excreted from the kidneys.
The elimination of end products from the body depends on the specific substance. Different substances are eliminated by various mechanisms, such as excretion through urine or feces, exhalation through the lungs, or metabolism and breakdown within the body. For example, waste products like carbon dioxide are expelled through exhalation, while others, like urea, are filtered by the kidneys and eliminated through urine.
Urea is produced by the liver and is excreted by the kidneys as a part of urine.

Drugs with a molecular weight of less than 300 mg are typically excreted through the kidneys via urine. This process involves filtration of the drug from the bloodstream into the kidney tubules, followed by reabsorption or secretion. The drug may also be excreted through bile into the gastrointestinal tract, where it can be eliminated in feces.

Although dialysis cleanses the blood of wastes normally processed and excreted by the kidneys, urination still may occur (although may be reduced).
Elimination is the process by which a drug is excreted from the body through the kidneys.
Kidneys filter waste from your blood so that it can be excreted.
as urine, produced by the kidneys
Water (e.g. a mixture of fluid) is excreted through the urine.Fluids are reabsorbed from the large intestines and then shuttled to the kidneys. The kidneys process fluids for excretion.
