Cerlapirdine (USAN; SAM-531, WAY-262,531, PF-05212365) is a drug which was under development by Wyeth/Pfizer for the treatment of cognitive disorders associated with Alzheimer's disease and schizophrenia. In a phase II clinical trial it demonstrated a trend toward efficacy along with a good side effect profile and no incidence of serious adverse events, but no further development has occurred since 2011.

It exerts its effects by acting as a selective 5-HT₆ receptor antagonist.
