Risperidone undergoes hepatic metabolism and renal excretion. Increased xylitol consumption can increase oxalate, calcium and phosphate excretion to urine. They decrease sodium reabsorption which leads to increased water excretion by the kidneys. Dosage is adjusted to maintain a reduced urinary excretion of uric acid. Their kidneys produce dilute urine for excretion. Ampicillin reacts with probenecid and methotrexate to decrease renal excretion. Increased solubility allows the excretion of unconjugated bilirubin in bile. A sodium load augments the intense potassium excretion by cortisol. Kidney causes involve increased excretion of magnesium. There was negligible urinary excretion of ivacaftor as unchanged parent. Protoporphyrin is insoluble and hence unavailable for renal excretion. Ofloxacin is eliminated primarily by renal excretion. It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion. Glycosuria is the excretion of glucose into the urine. Ouabain is eliminated by renal excretion, largely unchanged.
