Histamine H1 receptor (H1R) antagonists often have sedative side
effects, which are caused by the blockade of the neural transmission of the
histaminergic neurons. We examine the brain H1R occupancy (H1RO) and
the subjective sleepiness of desloratadine, a new non-sedating antihistamine containing amino acid group,
comparing loratadine, another non-sedating antihistamine, as a negative active control.
