The body has developed defense mechanisms that reduce the amount of foreign chemicals, such as drugs, that enter the body. One of the more prominent of these mechanisms is an a flux transport system that pump some drugs back into the intestinal lumen following absorption into the enterocytes and that is responsible for the lack of complete absorption of some drugs and removing drugs from the kidneys and liver into the urine and bio respectively. This efflux transport system is: A. Facillitat...

Drugs with a smaller volume of drug distribution have a longer half-life. B. Oral drugs are dissolved through the process of pinocytosis. C. Patients with kidney disease may have fewer protein-binding sites and are at risk for drug toxicity. D. Rapid absorption decreases the bioavailability of the drug. E. When the drug metabolism rate is decreased, excess...
