Bromides, specifically potassium bromide, proved to be the first medication able to control epiliepsy, having been discovered in 1857. The drug was to remain alone in it's field for over half a century and was eventually superseded by phenobarbital in 1912. The drug is still used as an anticonvulsant in veterinary circles. It proved useful as a sedative but exhibited many side effects due to a very narrow window of opportunity in therapeutic terms.
