PF-03654746 is a potent, selective antagonist of the human H3 receptor, developed by Pfizer. It was in the clinical trial phase II for the treatment of excessive daytime sleepiness (EDS) associated with narcolepsy, Tourette syndrome as well as potential anti-allergy applications and in phase I of clinical trial for the treatment of Schizophrenia and Alzheimer's disease, but these investigations were discontinued.

Sample Use Guides
excessive daytime sleepiness (EDS) associated with narcolepsy: Each patient will receive PF-03654746 tablets in a fixed dose titration schedule beginning at 0.25 mg QD for 5 days; then up to 0.50 mg QD for another 5 days; and up to 1.0 mg QD for an additional 5 days
Schizophrenia: PF-03654746 will be administered in a flexible titration regimen, beginning with 0.5 mg/d. If 0.5 mg/d is well tolerated, the dose will be increased to 1.0 mg/d after 5 days. If 1.0 mg/d is not well tolerated, the dose will be decreased to 0.5 mg/d, with the goal of achieving a stable dose of PF-03654746 within the first two weeks of dosing and avoiding further dose changes during the final week of dosing.
