Also known as Bithionol sulfide, Bis(3,5-dichloro-2-hydroxyphenyl) sulfide, 2-Hydroxy-3,5-dichlorophenyl sulfide, 2,2'-Thiobis(4,6-dichlorophenol), 2,2'-Dihydroxy-3,3',5,5'-tetrachlorodiphenyl sulfide, Bithin, 2,2'-Thiobis[4,6-dichlorophenol], 2,2'-Thiobis-(4,6-dichlorophenol)

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/ne
