Change in drug metabolism and elimination
Most drugs are eliminated through the kidney in either an unchanged form or metabolized by the liver. Therefore, the kidney and the liver are very important sites of potential drug interactions. Some drugs are able to reduce or increase the metabolism of other drugs by the liver or their elimination by the kidney.
