H1 antihistamines are often used in the medication for allergic diseases, coughs and colds, and insomnia, with or without prescription, even though their sedative properties are a potentially dangerous unwanted side effect that is not properly recognized. These sedative properties have been evaluated using the incidence of subjective sleepiness, objective cognitive and psychomotor functions, and positron emission tomography (PET) measurement of H1 receptor occupancy. This study is designed to evaluate brain histamine H1 receptor occupancy using carbon-11 doxepin after oral administration of levocetirizine 5 mg and fexofenadine 60 mg in normal volunteers.

Published
There was no significant difference between the mean brain histamine H1 receptor occupancy (H1RO) after levocetirizine administration and fexofenadine administration. Similarly, subjective sleepiness was not significantly different between the two antihistamines and placebo. Neither subjective sleepiness nor plasma concentrations was
significantly correlated with the brain H1RO of the two antihistamines. At therapeutic dose, levocetirizine does not bind significantly to the brain H1Rs and does not induce significant sedation.
