bro·mide (broґmīd) any binary compound of bromine in which the bromine carries a negative charge (Br−); specifically a salt (or organic ester) of hydrobromic acid (H+Br−). Bromides produce depression of the central nervous system, and were once widely used for their sedative effect. Because overdosage causes serious mental disturbances they are now seldom used, except occasionally in grand mal seizures. See also bromism.Medical dictionary. 2011.
