Cerlapirdine


Cerlapirdine 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.
