General description

Clemastine fumarate is used to treat multiple sclerosis, sneezing and rhinorrhea linked to common cold. It stimulates oligodendrocyte progenitor cell (OPC) differentiation and myelination.

Application

Clemastine fumarate salt has been used as a stimulator of rodent oligodendrocyte generation and myelination in vitro and in vivo.

Biochem/physiol Actions

Clemastine fumarate is an antihistamine H1-antagonist and anticholinergic that also has antipruritic activity.
