Bephenium is an anthelmintic agent formerly used in the treatment of hookworm infections and ascariasis (as a hydroxynaphthoate salt). Bephenium exerts its anti-helminthic action by inducing muscle contraction in parasites. The contraction is suggested to be mediated by B-type AChR receptors, which are activated upon administration of bephenium.
