Pharmacokinetic Changes in Elderly

  1. Protein binding of anesthetic drugs is reduced because of decreased levels of circulating serum protein—for example, albumin. Therefore, their pharmacologic effects are potentiated.
  2. Reduction in blood volume, an increase in percentage of body fat, and decreases in hepatic and renal function result in prolonged elimination for drugs dependent on redistribution and/or elimination for termination of action thereby prolonging anesthetic effects.
