![]() ![]() Use of bromide in cats is limited because it carries a substantial risk of causing lung inflammation (pneumonitis) in them. Potassium bromide is used in veterinary medicine to treat epilepsy in dogs, either as first-line treatment or in addition to phenobarbital, when seizures are not adequately controlled with phenobarbital alone. Medical use of bromides in the US was discontinued at this time, as many better and shorter-acting sedatives were known by then. Bromide's exceedingly long half life in the body made it difficult to dose without side effects. The British Army has historically been claimed to lace soldiers' tea with bromide to quell sexual arousal and in the Victorian era prisoners in England were compulsorily dosed with the chemical īromide compounds, especially sodium bromide, remained in over-the-counter sedatives and headache remedies (such as the original formulation of Bromo-Seltzer) in the US until 1975, when bromides were outlawed in all over-the-counter medicines, due to chronic toxicity. There was not a better epilepsy drug until phenobarbital in 1912. By the beginning of the 20th century the generic word had become so widely associated with being sedate that bromide came to mean a dull, sedate person or a boring platitude uttered by such a person. In the latter half of the 19th century, potassium bromide was used for the calming of seizure and nervous disorders on an enormous scale, with the use by single hospitals being as much as several tons a year (the dose for a given person being a few grams per day). ![]() Locock noted that bromide calmed sexual excitement and thought this was responsible for his success in treating seizures. At the time, it was commonly thought that epilepsy was caused by masturbation. Bromide can be regarded as the first effective medication for epilepsy. The anticonvulsant properties of potassium bromide were first noted by Sir Charles Locock at a meeting of the Royal Medical and Chirurgical Society in 1857. The pink color of the solution is artificial pure potassium bromide solutions are colorless The product is intended to be used in dogs, primarily as an antiepileptic (to stop seizures). BroVet veterinary pharmaceutical potassium bromide oral solution (250 mg/mL).KBr ( aq ) + AgNO 3 ( aq ) ⟶ AgBr ( s ) + KNO 3 ( aq ) Applications Medical and veterinary A bottle of PRN Pharmaceutical Company (Pensacola, FL) K This reaction is important for the manufacture of silver bromide for photographic film: ![]() Potassium bromide, a typical ionic salt, is fully dissociated and near pH 7 in aqueous solution. In high concentration, potassium bromide strongly irritates the gastric mucous membrane, causing nausea and sometimes vomiting (a typical effect of all soluble potassium salts). These effects are mainly due to the properties of the potassium ion-sodium bromide tastes salty at any concentration. In a dilute aqueous solution, potassium bromide tastes sweet, at higher concentrations it tastes bitter, and tastes salty when the concentration is even higher. ![]() It is freely soluble in water it is not soluble in acetonitrile. Under standard conditions, potassium bromide is a white crystalline powder. Potassium bromide is used as a veterinary drug, as an antiepileptic medication for dogs. Its action is due to the bromide ion ( sodium bromide is equally effective). Potassium bromide ( K Br) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US. ![]()
