The Pediatric Patient Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 4 Variables have a profound impact on drug action and effect Neonates (less than 1 month of age) Small body mass Low body fat content High body water volume Increased membrane permeability

The Pediatric Patient (cont.) Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 5 Variables have a profound impact on drug absorption No gastric acid present at birth No intestinal bacteria or enzyme function present Delayed gastrointestinal transit time Immaturity of liver, kidney, and renal excretion systems

Question 1 Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 6 Drug effect in a neonate differs from that in an adult because of the newborn’s: 1. Larger head to body mass ratio. 2. High body fat content. 3. High body water volume. 4. Decreased membrane permeability.

Absorption Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 7 Three principles in the pediatric patient The physiologic status (muscle mass and use) of the infant or child determines the blood flow at the site of intramuscular or subcutaneous drug administration. Compared with older children and adults, premature infants have immature and unstable body processes. A newborn’s skin, particularly that of premature infants, has a greater ability to absorb some chemicals because of its greater hydration.

Distribution Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 8 Two factors The chemical properties of the drug (do not vary) The physiologic factors specific to the patient (do vary)

Metabolism Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 9 The majority of drug metabolism, or biotransformation, takes place in the liver. In general, drug metabolism in infants is much slower than in older children and adults. Until 3 to 4 years of age, children have the ability to increase production of liver enzymes. Neonates have a decreased ability to metabolize drugs.

Excretion Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 10 Renal system may still be immature at birth Decreased glomerular filtration Decreased tubular secretion Decreased tubular reabsorption System still maturing over the first year of life Drug clearance can be compromised

Adverse Drug Reactions Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 11 Children are exposed to drugs directly and indirectly Transplacentally during pregnancy or delivery Direct administration Through ingested breast milk

The Geriatric Patient Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 12 Reacts differently to medications than younger adults do Drugs absorbed, metabolized, and excreted more slowly and less completely (stair – stepping) Variability in drug response and clearance related to aging organ systems and overall health or illness Patients age differently; body responses vary

Geriatric Patient Teaching Copyright © 2013, 2010, 2006, 2003, 2000, 1995, 1991 by Mosby, an imprint of Elsevier Inc. 13 Drug nonadherence related to: Drug cost Difficulty obtaining drugs Diminished cognitive abilities Lack of desire to take on schedule Depression Feelings of being overwhelmed with physical needs Physical disabilities requiring assistance to administer
