Pharmacokinetics of Bisoprolol

Elimination and Metabolism

Bisoprolol is classified as "moderately dialyzable" during hemodialysis, with approximately 18% of an ingested dose removed (adjusted for a 6-hour treatment) 1
The American Heart Association acknowledges that bisoprolol has a unique "balanced clearance" profile, with 50% renal excretion and 50% hepatic metabolism, which distinguishes it from many other beta-blockers, including atenolol, nadolol, and sotalol, which have predominantly renal clearance 1
The European Society of Cardiology notes that bisoprolol's balanced clearance mechanism provides several advantages, including limited accumulation even in end-stage renal failure, and that 48-hour plasma levels in dialysis patients are similar to those with severe renal dysfunction 1

In patients with severe or end-stage renal failure, the dose of bisoprolol should not exceed 10 mg once daily, according to the National Kidney Foundation 1
Similarly, in severe hepatic impairment, doses of bisoprolol should not exceed 10 mg, as recommended by the American Association for the Study of Liver Diseases 1

The American College of Cardiology notes that bisoprolol's balanced clearance differentiates it from other beta-blockers, such as atenolol, nadolol, and sotalol, which have predominantly renal clearance, and propranolol, carvedilol, and labetalol, which have predominantly hepatic clearance 1
The European Society of Cardiology acknowledges that bisoprolol's balanced elimination profile makes it particularly useful in patients with either renal or hepatic impairment, as it provides more predictable pharmacokinetics and reduces the risk of drug accumulation 1
