Barbiturates are excreted by?

Liver
Kidney
Spleen
Lungs

The correct answer is: Kidney

Barbiturates are primarily excreted by the kidneys because they are water-soluble and can be filtered out of the bloodstream through the kidneys and into the urine. The liver is responsible for metabolizing barbiturates, but it does not directly excrete them from the body. The spleen and lungs also do not play a role in the excretion of barbiturates.
