Thonzonium Bromide is a cationic surface-active compound. As an additive to pharmacologic formulations, thonzonium bromide causes dispersion and penetration of cellular debris and exudate, thereby promoting tissue contact of the administered medication. Thonzonium bromide is a component of FDA-approved Coly-Mycin S Otic, used for treating infections of the ear caused by certain bacteria. It has being shown that Thonzonium bromide inhibits RANKL-induced osteoclast formation and bone resorption in vitro and prevents LPS-induced bone loss in vivo, suggesting that Thonzonium bromide might be a useful alternative therapy in preventing or treating osteolytic diseases..   ^NCATS
