Half-lifeThe elimination half-life of propranolol is approximately 8 hours. The plasma half-life of propranolol is 3 to 6 hours.
Protein bindingApproximately 90% of propranolol is protein bound in plasma. Other studies have reported ranges of 85-96%.Approximately 90% of circulating propranolol is bound to plasma proteins (albumin and alpha1 acid glycoprotein). The binding is enantiomer-selective. The S(-)-enantiomer is preferentially bound to alpha1 glycoprotein and the R(+)-enantiomer preferentially bound to albumin. The volume of distribution of propranolol is approximately 4 liters/kg. Propranolol crosses the blood-brain barrier and the placenta, and is distributed into breast milk.
