PainCeptor Pharma is a private Canadian company focused on the development of drugs that act outside the central nervous system on nociceptors to treat pain. The company was established in 2004 through the merger of two academic spinout firms: Antalium from McGill University and NeuroCeptor from Queens University. At its inception, the company's primary operations were in Montreal and Kingston, and it established a partnership with the Danish company NeuroSearch as part of its birth.
