The Brain and Propranolol Pharmacokinetics in the Elderly

Abstract

Propranolol, a non-selective β-blocker, has been found to have a tremendous array of indications. Recent evidence has suggested that propranolol may be effective in patients suffering from post-traumatic stress disorder by suppressing activity in the amygdala and thereby inhibiting emotional memory formation. Dosage requirements have been well established in the pediatric and adult population, however, there has been no definitive geriatric dose recommended in the package inserts made available to the public. The aim of this paper is to use pharmacokinetic simulations in order to establish a pharmacokinetic profile dosage equivalent for the elderly as has been found in young patients. After completing the Monte-Carlo simulations for the elderly and young patients, a single 10mg dose in the elderly has shown comparable pharmacokinetic profiles as found in young patients administered a 40mg single dose.
