Bithionol is an antibacterial, anthelmintic, and algaecide. It is used to treat Anoplocephala perfoliata (tapeworms) in horses and Fasciola hepatica (liver flukes). __TOC__ ==Mechanism of action== Bithionol has been shown to be a potent inhibitor of soluble adenylyl cyclase, an intracellular enzyme important in the catalysis of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP). Soluble adenylyl cyclase is uniquely activated by bicarbonate. The cAMP formed by this enzyme is associated with capacitation of sperm, eye pressure regulation, acid-base regulation, and astrocyte/neuron communication.

It is related to the organochlorine hexachlorophene, which has been shown to be an isomer-specific inhibitor of soluble adenylyl cyclase. Bithionol has two aromatic rings with a sulfur atom bonded between them and multiple chlorine ions and hydroxyl groups attached to the phenyl groups. These functional groups are capable of hydrophobic, ionic, and polar interactions.
