Fontan-associated liver disease suppresses hepatic CYP enzyme activity and reduces first-pass metabolism, increasing bioavailability and systemic exposure of drugs. Hypoalbuminaemia from protein-losing enteropathy elevates the free fraction of highly protein-bound agents, rendering standard total drug concentration targets unreliable. Reduced cardiac output contracts the volume of distribution of hydrophilic drugs and diminishes renal perfusion, while creatinine-based glomerular filtration rate equations systematically overestimate true renal function due to reduced skeletal muscle mass, leading to inadequate dose reduction for renally cleared agents. These disturbances are predicted to affect the pharmacokinetics of every major cardiovascular drug class prescribed in this population, including anticoagulants, antiarrhythmics, neurohormonal antagonists, and pulmonary vasodilators, although direct Fontan-specific pharmacokinetic data remain scarce and confirm these effects for only a minority of agents, with dosing largely extrapolated from non-congenital populations.
