| Other Factors Affecting Drug Absorption and Distribution In addition to protein availability, other factors may affect drug absorption and distribution in the body as a whole or at specific sites within the body. The following table highlights some of these other factors. Factor Discussion Regional blood flow Reduced area blood flow can be seen in diabetics and enhanced blood flow can be seen in tumors. Lipid solubility of the drug The more lipophilic a drug is, the more likely it will enter the central nervous system. The integrity of the GI tract In a diseased gut, an orally-administered drug may not be absorbed as expected. Age Drug kinetics and dispositions change throughout life. In general, metabolism of drugs is reduced in the elderly. Genetics Mutations or deletions in drug metabolizing enzymes can greatly affect a drug's disposition. | View Page |
| Why TDM? However, every patient is unique. Changes in the gut (if the drug is taken orally), genetic variations in the liver's metabolizing enzymes, and the status of organs (like the kidneys and liver) all affect how a drug will be handled by an individual. TDM helps to ensure that a dosing regimen is appropriate for a given patient. | View Page |
