The nurse is aware that a patient with liver disease and a decreased albumin level may develop which of the following effects?
a. Toxicity on normal doses of medication
b. Less active medication available in the body
c. Reduction in therapeutic effect
d. Accelerated biotransformation of the medication
A
Most medications bind to albumin to some extent. When medications bind to albumin, they are unable to exert pharmacological activity. Only the unbound or "free" medication is active. Older adults and patients with liver disease or malnutrition have reduced albumin, which increases their risk for medication toxicity. With less albumin to bind with the medication, more "free" or active medication is present in the body. This would result in an increase in therapeutic effect and possibly in toxicity. Most biotransformation occurs in the liver, although the lungs, kidneys, blood, and intestines also play a role. Patients (e.g., elderly, those with chronic disease) are at risk for medication toxicity if their organs that metabolize medications do not function correctly.
